gt4 muffler, on st/gt Options

[Hanyo]

Would it help performance to add a gt4 muffler and custom 2.25 inch piping to a st or gt?

giving the fact that the gt4 has a 2.0 turbo engine, the muffler should flow much better then the stock st or gt mufflers.

you might say : " just why hanyo, why? go get yourself an apexi or greddy .... ect"

well my main reason is because i like my car to be quiet. There are way too many ricers around my town and I dont want cops to think i am one of them. Secondly, my town has a extremely high car theft rate, so I want to keep my car stock looking as possible.

do you guys think the gt4 muffler would help?

since it is made fro the 3sgte i would imagine it would have less backpressure than a st or gt muffler. It wouldn't necessarily have better flow though.

Pipe's route might be different

Go for the custom piping and a flowmaster or similar muffler, they're not 'rice' by any means, just made to sound like its a real car .

yea,,, just don't get a magnaflow or a flowmaster... or I'll slap you myself.

what makes an exhaust quiet isn't neccesarily the muffler, but the resonator. Even fart cans can be made quiet with a good resonator... for the most part, you can fit just about any muffler on any car, since mufflers only requirement for fitment is size. For example, I have a 3 foot (or something like that) glasspack before my muffler (flowmaster 40... suck it fallen... =P) and it's pretty mild.

Not sure what the objection on the MagnaFlow is -- unless you've had the joy of a) a MagnaFlow race muffler on a street car or b) a MagnaPack standing in for a full muffler.

MagnaFlow makes straight-through mufflers that are the same size and dimensions as stock, but flow much better. Because they're properly designed with good absorbtive material, they tend to avoid the echo-chamber effect of the fart cannon. Since they're full-sized, they tend to be minimally louder than stock until WOT, at which point they roar.

If you're putting in custom piping, definately get a resonator or a mid-muffler of a good straight-through design. Heck, get both, there's room.

Glasspacks aren't resonators, though people often incorrectly equate the two. A glasspack is a primitive absorbtive straight-through muffler. Often they use a louvered instead of perforated pipe to channel the exhaust gases, which defeats the whole free-flow concept, but they never use the kind of high-grade sound absorbtion a modern straight-through muffler uses.

A true resonator uses sound cancellation, bouncing sound waves onto each other and translating the noise into (miniscule) heat. The stock system comes with a resonator, not a glasspack. Easy test: tap it with your fingernail. A resonator will ping like a bell, while a glasspack will make a dull thud.

im speaking from experience, i have a magnaflow exhaust series 2 and im amazed at the sound... not much louder than stock at idle or cruising but when u get on it they people around you know that u are, i've had a lot of comments on how non-ricey the exhaust sounds and the depth of it... full 2.25 exhaust

[Hanyo]

hey kwanza26 can you post a sound clip of your exhaust?

the exhaust i really want is the greddy sp 1, but i have heard complains that the dampaning material gets blow out and gets louder over time.

I plan on getting header, test pipe, glass pack, and a greddy or tanable muffler. what do you think it will sound like?

What is a very stock looking muffler?

I'd suggest skipping the glasspack and going with a modern tube muffler (e.g. MagnaPack or XL PowerPack). With a layered insulation consisting of stainless steel wool around the pipe, backed by a ceramic sound absorbtion fibre, you won't run the risk of the material blowing out the way you do with a glasspack, which afterall is just fibreglass. The price difference isn't really that great, say $10.

BTW, the Thrush claim of CRF (continuously roving fibreglass) isn't deliberate. It's inevitable, since you can't make the fibreglass stay still. What's also inevitable is that as the CF moves around, it will make its way out of the perforations.

i have a tananbe racing medallion with 2.5" straight pipe. without the silencer it's loud so i had a silencer on. here's videos i made earlier, in car and while driving.
