Would I be better with race pipes or crawford cats?

 

Race pipes would make more power, but would most likely sound raspy with the Nismo catback. I'd get the crawfords.

 

gut stocks i wanted to do that today but i dont know what tools i need

 

Dont you need 02 simulators for the race pipes

 

I have the NISMO exhaust with Crawford cats--- sounds great!
no raspiness...

 

How do you know if your cats are gone? What are the symptoms?

 

kinetix resonated test pipes dude. that's the way to go. all th epower, none of the raspiness. a bit more money but i'm happy with the results. they also come with the o2 bungs welded on already which makes it nice and easy to swap. no cel after install.

leatherface- you know you've got no cats when you take them off and replace them with test pipes (race pipes).\\\\


PUI

 

so the only symptom I will notice is the increase in raspiness and sound? how about performance?

 

dynos typically show somewhere around 10hp at the wheels gained. my butt dyno isn't accurate so i dont know since i've never dynoed. i'll take veryone elses dynos as truth.

 

If you dont mind the rasp and want race pipes....Gut the RT's . If I had it to do again..... I would have taken my gutted RT's and tried some way to add very heavy steel wool type stuff to the inside of it . To try to get rid of the rasp . I ended up getting the Crawfords and Im very happy with them....Bill

 

How loud would this be?

I had a buddy put straight-through race pipes on his Supra and all he did was get pulled over for loudness.

 

resonated test pipes aren't very loud and dont really rasp.

 

I agree with the resonated test pipes. All the power of straight pipes but without the raspiness and not as loud. Actually, jsut a tad bit louder than before.
