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?

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.
