Dual exhaust [Merged 7-9]

[WMD]

Im saying many people think it pointless to put dule exhaust on a 4cyl. But if its done correctly it could look good. I would try for the srt-4 look if i was doing this project.
BTW i have seen mustangs with dule fart cans and I all the way home.

 

[buugiewuugie]

If it will hurt my performance I wont do it. But if i can help or at least not take away from my performance and make my car look good at the same time I would like to do it... But I am not doing fart cans. It would be one dual outlet muffler where the cat would be and two about 2 1/2 to 3 inch stainless steel tips out the back

And I have seen the same here... sounds great... right....

Well your a turbo so it wont hurt you. There are so many threads out there about backpressure this and that and to big of a pipe size etc. But for a turbo, a big exhaust is fine. Personally i would do 2.25 or 2.5 since it would equal a pipe that is 4.5 or 5in in diamiter.
Oh and have someone photoshop dule tips onto your car to see if youll like it.

 

[WMD]

Well this is a 2g FWD, so just copy this design and youll be fine.

alright thanks for the help!

Yeah because all the muscle car guys have angled fart cans coming out of the back of their cars.........

it dont have to be angled.. at least mines not.

I've always heard that, with a turbo, where the exhaust splits it messes with the vortex of exhaust air coming out, creating backpressure.

I haven't read any of the other posts about this, but it seems to me that with a 1g AWD, there would be a problem with space....The gas tank sits along the whole rear of the car, leaving just enough room for the stock exhaust...Last time I was under my car, it didn't look like there would even be enough room to run a split dual exhaust.....

And now for a personal opinion, which you may feel free to disregard completely: I think dual might look okay on a 2g, but I really, really, really strongly believe that *any* exterior mods on a 1g (whether they be body kits, wings, weird exhaust, what have you) just look out of place and....weird. 1gs have a very distinct styling that doesn't take well to customization, in my opinion. Just food for thought

It will not hurt performance except that the weight of that second exhaust. Thats why a lot of mr2soriginally came with dual and they switch to single as it adds a lot of unnecessary weight to the vehicle. All these guys throwing cf hoods and being like, LOOK HOW MUCH WEIGHT I LOST, and then throw on dual exhaust and that makes it heavier than before. SS steel is heavy so be wary of that.

I thought about putting dual exhaust on my car, but never really saw anyone do it before and I wasn't sure how to do it. I'd like to see dual exhaust, but have the exhausts come through the side skirts in front of the rear tires. Too bad that's not possible.

Exactly. There's a reason that V8s have dual exhausts, and 4-bangers do not. There's a guy here with a 2G who has dual exhaust, but he's non-turbo & a ricer...

 

[impuresoul2k3]

I personally think it looks badass on a 1g. There is a pic somewhere in the gallery of a black 1g with duals...

 

[Ultimatedsm]

I think it will hurt performance to be honest. Now there will be more bends and kinks for the exhaust pressure to go through. Instead of just flowing straight, now it has to flow through the exhaust manifold to the downpipe, then split into two pipes, then go through all those bends and finally out of those muffler. V8's have TWO headers, one pipe per header which makes most of them DUAL exhaust. 4 bangers has one header or exhaust manifold so one pipe. It just makes sense, so if you want to waste your money to look good but perform less and add weight, its up to you buddy.

Do what you want with the car, it will not really hurt your performance. You can just have a branch of piping that will go to the right side of the car (2-3 feet) from the muffler.

All you gotta do is fabricate hangers and plan the piping. And of course, cut some of the rear bumper if youre gonna use the stock rear.

c5chris is refering to this: (2g btw)

But when you can see the y pipe at the end it is a moment. Alot of acuras and accords with v6's have this and i can only . But hey, it come from factory that way.

 

[Ultimatedsm]

Why don't you guys see that picture and tell me it won't hurt performance? Look at that man, it will just add back pressure, and for turbo cars, thats a no no. Longer piping with more kinks or bends and more mufflers = restriction period, end of discussion.

 

[Mar10]

i personally think dual exhaust looks awesome. but thats all its for..looks. if your thinking of performance in anyway, i'd leave it.

 

[fourreGsixty3]

Ive got to agree with femmeDSM and Ultimatedsm. For one, have you put your car up on a lift and looked under it? If not then I'll tell you that you would have to cut into your gas tank to make the room for the piping of the second exhaust because the gas tank goes across most of the rear bumper, execpt for where the stock exhaust is, and all of those unnessisary kinks and bends will definately add to back pressure like ulimatedsm said. Huge with turboed cars such as ours. To add to this as well, the 2Gs it might look ok, but 1Gs it would look real wack like femme said, and IMO the only exterior modds on a 1G should be a new paint job, clear corners, headlights, refuerbed swirlee rims(stock ones on most 1Gs), and wax. But thats My personal opinion so disregared it if you want.
G'Luck with what ever you deside to do. If you do dual exhausts post a few pics on here so other people can see what it looks like on 1Gs.

The SRT-4's are running dual exhausts and it doesn't appear like they have any troubles with it.

Man i love pics. Most of the time they say everything and show everything.

I considered this back in the day and who knows I still might. I love my thermal but im def not a big fan of its 5" tip and liked the dual look on the srt4. From what I read you wont gain a damn thing but at the same time its some added weight and bends and the loss is minimal. Not sure how the rear of a 1g awd differs from 2g awd but id imagine its pretty tight to squeeze pipes back there. I think for a non-performance mod you should go for it if you want to. Yes its a 4 cylinder but if the cars clean I cant see how people would consider that "rice". good luck



hell Dan Cokic is running dual outlet exhaust

wow that dosent look to shabby. He did a pretty good job with the dule muffler look.

 

[BoBbOrAzE]

yea I agree it looks clean and well done. I bet on a it would look just as good if not better on a 2g after modifying the bumper a little.

I think I may look around for that backpiece of the srt4 exhaust, and fabricate an extension to our exhaust to the center to utilize it, then bolt it on and see how it sounds. Anyone know the diameter of it?
