Exhaust for 95 GSR
I was looking for a catback exhaust for my 95 GSR. I wanted to know which cat back would give me the deepest sound...I dont like the high pitch sound that a lot of catback systems put out. Also, what would be the best system as far as power gains? Thanks for your help.

Our 4 cylinder engines really don't have that deep low pitch growl that the 6 and 8 cylinder blocks have... one way to get around this is:
If you have money, look into investing in a twin loop muffler such as the hy-tech twin pass or the mugen twin pass, this would make the exhaust note a bit quiet and not "farty" like most cat backs. The beauty of this is that the exhaust is quiet and flows just as well as a straight through.
Also, look into the type of resonator that comes with each cat back system, this also plays a part in the exhaust tone.

The resonator uses the reflection method and will determine the exhaust note based on it's size. The shell of the resonator is sized so that when sound waves enter, they will bouce straight back to the center and be cancelled out by the following sound waves. The longer the resonator, the more sound waves get bounced around and cancelled out. Some exhaust manufacturers will use two smaller resonators instead of one large one.
The method that the resonator uses to decrease noise does not have any adverse effect on performance. Alot of people are mislead into thinking removing the resonator can free up exhaust flow. HyTech Exhaust in Irvine, CA tested their catback with and without a resonator and the dyno showed a difference of 2whp in favor of the resonator.

you don't always have to buy the whole system, A lot of people mix and match. the Exhaust is essentially just a pipe...
