Muffler Delete

[screamingdemon]

I've searched around, found a couple of threads here and there regarding a "muffler delete". I see some people say do it others say don't. I've noticed on alot of the new vehicles they sell muffler deletes, such as for the newer Camaro's, SRT4's don't even have a muffler stock, saw a few people doing it to their new Genesis 2.0T. All of which sound great.

I've looked around and all I've been able to find was one video of someone doing a muffler delete on a 2g DSM. It sounded pretty good for a cheap mod. Don't get me wrong I'll eventually be getting a Megan Racing downpipe/Thermal R&D catback for performance reason but I figure why not at least give my car a semi-sporty tone. My car's so quite that it annoys me.

Here's the video...

Do you have emmisions where you live?

Nope, sure don't. Had also thought about throwing on a test pipe possibly.

Around here we say F it.If your going to keep modding or want the most exhaust.We just go turboback.

Your in luck tho.I bet you can peice together one for cheap.And black friday is 2 days away.

In your case a 2g..The stock o2 housing can be ported, leaving you with downpipe,"test pipe" and catback left on the list.

Since you have no emissions just straight pipe it and be done with it

I am currently running open down pipe on mine. Not by choice if I must add. The guy before me decided to attempt a weld on the whole exhaust before he realized welding was not his cup of tea. If you want my honest personal opinion, I would say leave your muffler or buy an aftermarket cat back. The way mine sounds turns heads and people "oooh and ahhh" when I drive by, but after the first day having to the radio on full blast kind of starts to get old. Id just buy a bigger pipe and throw a nice can on it if you want it to sound good and not become a daily headache to yourself.

Sorry for the missing words.

we did a muffler delete on my friends a4 1.8t and it sounds good at idle but when hes gets on it it gets pretty raspy i would try a resonator delete first idk about your car but my talon has one huge resonator that seems like it would make a pretty good diffrence

if you don't want it to be raspy, this is a bad idea, as a resonator greatly reduces rasp. So does a hi-flow cat.

I think that sounds pretty good, a muffler delete=fail imo.

I'm doing a muffler delete here soon, I had to go without a muffler for a few days once because I couldn't find anyone to put one on. The best part was you could hear the turbo down-spooling through the exhaust

I have a muffler delete with stock size pipe and factory cat and I like the way it sounds. It gets me buy intil I get my 3in DP and have someone 3in straight pipe it.

Muffler delete only with turbo back piping tho, to just home-made style cut off your muffler off of the factory exhaust system is kinda lame. I'm sure people do it in a pinch tho...

Hey, you're back! . My previous owner actually for some reason rigged up a 2.5" downpipe welded to a 2" pipe, catless, to a stock muffler. I've still got it, with an autozone fart can. If you're looking for loud, just get a can, theres like nothing in it, so it just makes the tone deeper. Mine gets ear piercing around 3k rpms and its pretty close to stock exhaust.

I just cut the back part of the exhaust off. Stock cat and resonator. Sounds good and not at all very loud like a no cat.

Of course this is only till i fix my apexi exhaust or install the evo kit with my thermal exhaust

I like running a 3" catalyst then a straight pipe to either the back or the side. I like the sound, I always pass emissions in Oregon (you wouldn't in Ca or a few other states), and if you keep your foot out of it it can be relatively quiet. You can always add a 3" resonator, or a 3" muffler. Just a catalyst and resonator often sounds nice.

I've always been a fan of the APEXI N1 muffler or the HKS carbon/titanium muffler but the "straight thru" kinda mufflers for some reason attract to many piggys.

The company VIBRANT makes a high flow muffler that comes flat black in color and flows super good and ALMOST looks stock. I've bben considering replacing my apexi muffler with a vibrant or maybe a flow master.

The straight thru mufflers are hands down the best but damn cops wanna pull a guy over to much with that set up.

Vibrant or flowmaster is sneaker style

Since were on toppic of mufflers and exhaust system, how many people run a back pressure gauge? Maybe I should start a new thread? Steve, you run a back pressure guage?

Its pretty good info to have. I tap a diesel boost gauge (the type that doesn't read vacume) into my exhaust manni. I have my exhaust mannifold pressure gauge mounted right next to my intake mannifold pressure gauge (boost)

At 33psi boost I'm peakin bearley about 19-20psi back pressure

I have a 3inch straight pipe with nothing on it at all there's no rasp at all it sounds like a diesel truck at idle and you can hear the turbo spool loud as can be sounds awesome I think and it's really not that bad in the car but it is super loud outside the car even cruising and you will get pulled over if a cop sees you but at wot it sounds awesome
