I need to order some cats, next week and need some last minute input.
where can I order catz without the $500 price tag (most likely crawford)

- i'm ordering catz cuz they don't throw out the engine light
- no rasp
- con is that the price is much higher

peeps with testpipes

- anybody that 'doesn't' experience rasps?
- any quick fix to engine light cell?

any other inputs?

 

I did a Froogle search for these manufactures...

High Flow Catalytic Convertor
Ultimate Racing
LaBree Motorsports
Central20
Mines
Power Enterprise
Crawford Z Car Service
NISMO
Random Technology
Kinetix Racing

...then selected the best price. You can do the same.

 

resonated test pipes with non-fowlers will not throw CEL's

 

Crawfords have no rasp. and they look just like stock.And the service is the best.

 

i like my kinetix cats ^_^

any test pipes runnign non-foulers will not throw a SES

 

the SES will goes away after few thousand miles. No problem in my case for the last 7 months.

 

I like my Labree resonated test pipes. They are top quality with very little rasp. Do a search for labree.

 

had kinetix HFCs for almost one year, no problems.

For NA I would go with HFCs
Turbo, I would go with TPs

 

^^ what he said..

 

With test pipes, rasp is inevitable unless you buy the resonated ones.

 

Is it true that resonated TP's have less of a hp gain than non resonated?

 

what about if you are going the nitrous route? hfc or test pipes??

 

more air flow on non-resonated? 1 or 2hp more? no one can really have a solid proof for it.

 

So would high flow cats be a complete waste of money on a turbo car? Test pipes the only way to go to see a good power gain?

 

cats won't be a waste of money in a FI'd car. I'm thinking since non resonated TP's got straighter/smooth passage, it should allow the air to be exhaled more freely, therefore more power.

 

hp gain between the 2 are the same. Just one will cost twice.
