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?

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.
