Local shop is selling a 3" magna flow exhaust and is brand new and install for 500, Or theirs a guy on here selling a thermal rnd 3" full system for 375 shipped and looks pretty good and get it installed for 100. Which system will benifit me more. I like a low sound when idling but a nice lil roar when you floor it, But dont like it when its load when ## crusing down the highway and cant talk inside the car. Or theirs the apexi I could buy as well. Which in ## opinions would be the best or another system you know of thats better then these. Thanks again
 
Your going to have someone else install an exhaust..Pick up a socket set dude, your a dsmer now..Save yourself some money..


Everyone likes thermals...But then if you have it installed your looking at more money...
 
I have a Thermal, it is by far the best exhaust I have had in a car. DOes not draw attention and the sound is low while cruising, under wot I don't know because I have an open dump tube :)
 
I have an apexi n1 no cat just text pipe. I've never had any complaints about my exhaust being loud, even on the highway. As for sound of the others? i went on youtube and looked up a bunch of videos that people put up of their systems. I dont care much for magnaflow mufflers since almost everyone has one on their car nowadays. I know of alot of people that run thermals and absolutely love them. They make good stuff, not cheap crap.
 
All i have to say is, whatever you buy for exhaust parts make sure that your downpipe is the same brand as your catback!! I made the mistake of buying 2 different brands, thought if they were both 3" and for the exact application that it would work. The flanges were angled weird so I had to weld and modify.

And avoid buying cheap ebay exhaust parts!!!!!
 
I would install myself but I never get anytime I am in military and that burns up all time. Ill ###### just go over a friends house and try and doing it if I get time. But thanks for all the responces ill ###### just go with the thermal thanks guys.

x2 i did the same exact thing except i'm using a buschur downpipe. The apexi n1 downpipe takes care of the cat delete part.

Exhaust parts are some of the few parts that you can get away with purchasing from eBay. That's not to say that there aren't some bad systems out there, but I haven't heard of anyone who has had an issue with an exhaust system from a seller with almost completely positive feedback. My cat-back is from eBay and I couldn't be much happier with it. It fits fine, sounds fine, and has held up for almost three years so far.

To the OP; If the Thermal is cheaper, I would pick that over the other one being that they do sound pretty good. The installation of a turbo-back exhaust really is pretty straight forward too. It can be a little annoying if you don't have a lift, but it's still completely doable for anyone with even modest mechanical ability.

Well I was mostly referring to eBay manifolds that are prone to cracking or the cheap o2 housing that was never designed to fit correctly.

I haven't read / heard anything bad about ebay downpipes or catback systems I just figured there's probably chinacraft downpipes on ebay too if they did what they did for the manifolds and 02 housing.
 
The best tbe exhaust system i've seen on a DSM is an Apex'i GT Spec but it's hella expensive. I think like $1200 or something ridiculous like that. A buddy of mine had it on his Spyder. I could shove my fist in the end all the way up to my arm pit. And the note was like nothing i've heard on a DSM, super low even at WOT.
 
Ok well I bought the thermal off the guy on here, Just got to get the downpipe, manifold and o2 housing. Any1 have any idea on what the o2 housing is for the evo 3 16g turbo. Or a nice manifold for it. Thanks

a 14b O2 housing will fit on an Evo3 16g. An open dump O2 housing will help minimize turbo creep which Evo3 16g's are notorious for, but they are very loud and not street legal. A good choice for manifold would be an authentic Evo3 manifold. Equal length tubular would be nice too, but they can be pricey if you want one that won't crack or oxidise.

As for downpipes and whatnot, there is nothing wrong with Ebay as long you can verify the parts fit. Anything with non-moving parts is usually pretty safe to get from Ebay.

Good choice on the Thermal purchase, you should be happy with that. As for a downpipe, depending on how much money you are looking to spend, punishment racing sells awesome exhaust components for those on a budget. You can almost always find someone on here selling all sorts of downpipes for cheap.

A manifold that I would suggest getting would be an FP race manifold. One of the best manifolds for the money, especially when you catch them on sale! You def wanna stay away from ebay manifolds. They are very prone to cracking, and the flanges being warped. Forced Performance Turbochargers: FP DSM Race Manifold

And for the o2 housing you will also need to ask yourself what kind of money you wanna spend. If you are goin to go with an Evo316g, you can port-match you o2 housing to match up and bolt on for nothing but some time. You could buy an evo3 o2 housing, or you could buy a stainless housing in either a recirc style or a dump to atmosphere style. All up to personal preference.

All of the 7cm^2 housing are gonna be prone to boost creep. A dump will help, but to a very minute amount on lower HP applications. You will see better results by porting the turbine housing. The best way to keep creep down is to keep the exhaust restricted!
 
3" Thermal cat-back, Megan 3" downpipe.

Depending on your emission laws, cut flange off cat-back, take it to that muffler shop you're probably talkin' about, get them to weld the flange to match the Megan flange and weld a steel piece to eliminate the cat. ---- might cost you like 20$

I'd love to make an idle vid = disgusting. You can be heard forever a way when downshifting as a low, mean rumble. Acceleration is music to the ears and when your wastegate opens you'll make every one run scared, especially the Honda nerds.(no offense). When cruising you can talk/hear perfectly fine. Not true while under acceleration though. ;-)

While it is true that tubular manifolds from eBay sellers have been known to crack easily, the OP was asking about turbo-back exhaust components so telling him to avoid eBay was not necessarily good advice.

I can agree with both of you on this one, but as we all know, it is best to advise our new dsm'er to be very eery of anything on ebay. We have already made the mistakes in the past. No reason for them to do the same. There are certainly things you can safely buy from ebay and there are def things that you can't.

To the OP: if you are not sure on a part, especially on ebay, either use the search button on here or just ask us! :thumb:
 
You'll love the Thermal. Trust me I've used 2.5" turbo back with a hiflo cat and a magnaflo muffler and it was way to loud for me. I've also had 3" turbo back with hiflo cat and Apexi N1 catback and that was much quieter and had more of a higher pitch roar at wot probly due to the 2 resonators before the muffler. The N1 muffler rotted out on me though after a few winters here in good old new england. Right now I'm running a 3" apexi cat delete downpipe with 3" thermal catback and it by far sounds the best out of all of them. Its pretty quiet at idle and at wot it's got a nice deep rumble unlike any other 4 cyl I've ever heard with exhaust. :thumb:

This is my thermal catback with the stock downpipe and cat. If you have a sub hooked up to your computer turn it up to get an idea how deep it sounds.

Thanks for all the responces you guys are helping me out alot! But 99gst thanks for the link! I will be buying, An as for the o2 housing im not really familar with all that a little more knowledge on what Im suppose to do. You gave me all those choices LOL and I have no idea on whats the best or what some of it mean sorry Im a noob to cars atm but Im learning.

This is an o2 dump. When the wastegate on the turbo opens to relieve exhaust gasses and control boost pressures, it gets dumped out. When you dump to the atmosphere it is very loud. There is no power gain or realistic advantage to running one. It is all personal preference. They sound mean when the wategate opens, but they can attract unwanted attention and they do tend to leave alot of black soot on anything in its path. The theory behind them is that with a recirculated o2 there is a very short distance between the exhaust path and the wastegate port. When the wastegate opens, those gases get mixed with the free flowing exhaust. That short distance between the two creates turbulance, which can hurt exhaust flow. Not good for a turbo. Turbo's only flow as much as free as its exhaust. Really a dump is only good for larger turbo setups flowing alot of air. Smaller turbo's will survive just fine on a recirc housing. Again if you want it lound then by all means you can get one. Nothing wrong with that.

This is a recirc. housing. Just like what comes factory on our cars. Quiet, clean, effective. Hope this helps you understand a bit better.

Up to you on what you want and what you can afford! Either way its still a dsm so it all rocks to us! :hellyeah:
 
Honestly if your just starting out modding then you won't need that fp manifold right away. A ported 2g manifold can go a long way and can be found for far cheaper than the fp one.
 
Will the fb benifit me more in long run?? Cause I plan on going to atleast 400 hp. Soon as taxes hit =]


Have you got all your maintenance done on the car? That should be the first thing you do especially if your shooting for 400hp. To answer you question yes it will be more beneficial in the long run if you don't mind spending the extra $200 on the fp one. Just an FYI there are plenty of guys here on tuners making 400hp but its not as easy as they make it look.

ETS makes great intercoolers and that is very nice deal on them.
 
Also that 3" inch downpipe off punishment racing should bolt right up to the rNd right?

When everyone says do the maintenance, We talking about oil pan,water pump,timing belt?? Or give me examples so I can go out tommow and get it all tooken care of

Ok so the ets ic is worth the buy?? Ill most likely go with the racing one their selling so it fits my car just right.
