I have a JWT TT with stock cats and I am looking to either go with test pipes or hi flow cats. However I have been told that this can cause oil consumption issues do to the turbo seals require back pressure to properly seal. So please chime in what are you guys using and is it causing oil consumption?

 

hmm i dunno about that. i know plenty of people who are N/A and have the oil consumption problem

your best bet is test pipes for a TT set up

 

No JWT TT owners out there???

 

there is a thread on my350z that is identical - check the responses there.

 

Ya I started a thread on my350z due to lack of responses here.
