Im going to be running close to 15 pounds in a week or so once my motor is finished.

I have a stock 94 cat. How bad will this hurt my numbers? if its like 10whp Im not going to stress, but if its like 20-30, yes I will stress

Any opinions on this simple yet bothering matter?

BTW, its a 94 gsr, drag 3 turbo, tanabe hyper medallion exhaust(i think its 2.5")

 

I'm sure you'll lose more than 10whp at 15psi with the stock cat.

 

You will for sure lose 20+ whp with stock cat on 15 psi... Why don't you wanna run a freeflow or extend the downpipe to the exhaust... ...

 

Try a High-Flow Cat. They will prolly be close to a testpipe but Legal.

 

well im broke as crap right now after gettin all this motor stuff in.

Im REAALLY want to run a testpipe, but I REALLY dont want a buzzing ricey sound. I love the quietness of my muffler right now.

Can anyone with expereince with testpipes give me some first hand input on this? I cannot afford a high flow cat right now.

Thanks

 

Get a test pipe that is Resonated. I have just a straight threw and it is a bit loud. My girlfriend doesn't like it that much. I have heard the resonated ones help out quite a bit as far as quiteness.

 

where are these resonated test pipes? i never heard of them.
