exhaust on 97 gsr
i have a 97 gsr with generic racing headers, and a magnaflow muffler, and stock cat i think and stock piping. i want to cut all that old **** off since its rusting and sounds bad. i only say it sounds bad because i was in a car show last weekend and in the muffler comp. i noticed it sounded alittle flimsy compared to the others. i took second place. i still want to re-do it. i want to cut the cat off and leave it and get new pipe. what size should i get to make up for less backpressure without the cat. i know i should get one, but i want to eliminate that and increase flow, to maybe get a deeper more rumbly ingine sound.

Re: exhaust on 97 gsr (97superteg)
just get a catback exhaust and dont deal with all that cutting ****. and if you still dont want a cat put a straight pipe in . it may cost a lil bit but its really worth it
Your best bet is to go with a full exhaust, from the cat back. Depending on how built the motor is, you will need to figure out what diameter piping you need to make sure that the motor breathes good without losing low end.
That being said, and the fact that you have a stock 97 gsr motor, i wouldnt go with anything over 2.5
If you plan on keeping that motor completely stock, with the exception of an intake, header, and exhaust, i would go with 2.36 piping. That would give you optimal flow i think.
If you build the motor a little more, like intake manifold, cams, pistons, etc, i would opt for a 2.5 inch system, since it would help let it breathe much better than a 2.36
As for the cat, i would go with a magnaflow high flow. You cannot get a better cat than that imo. They flow just as good as a test pipe, and it wont be as loud, and wont pollute the air as bad. The difference between a high flow cat and a test pipe is sooo minimal that youre better off saving the environment a little and just getting a high flow.
There have been numerous tests comparing lets say Omni and T1R test pipes, to a magnaflow high flow cat, and the difference was a mere 1-2whp ( test pipe made 1-2whp more than a cat). That little power difference, IMO, should be the deciding factor to get a high flow.
