Is there a such thing as a TP that doesn't crack or O2 sensor falling out? I'm looking to get a straight pipe. No resonators. But I keep reading that they crack. Some say the resonator TP are better cuz they allow for flexing and movement in the exhaust and engine but isn't that another thing that could go wrong and restrict some flow?

 

do a search you will see most of had cracking issues due to either cheap megan test pipes or test pipes with a heavy *** nismo exhaust. i ran test pipes with jic exhaust and y pipe with no issues for over a year. just make sure which ever you go with they have the brace mounts that bolt up to the tranny brace.

 

does it really help that much? i notice the APS Test pipe has it but alot of them don't.

 

Do a search before buying anything. It seems the more expensive ones (generally better quality) have the braces that were mentioned. However, I have also read that unbolting that brace allowed more movement and eliminated the cracking. I have no personal experience of it yet, so reading up on it more will be your best bet.

 

It depends on which cat-back exhaust your running. I had no issues at all with my HKS TD and non-rez test pipes.

 

I THINK Motordyne is coming out with test pipes...
