Hey do you guys know if the tomei expreme ti test pipe will fit with a catback exhaust other then the tomei single catback or do u need the single tomei for the test pipe to work?

 

It probably necks down to 2.75" at the flange like the Tomei catback does, but it'll fit with a regular 3" flange as long as you use a good gasket at the connection.

 

it necks down, i would suggest not getting one. Mine just broke right at the one of the welds. it cracked about 80% around, almost in half. Myself and many other have had these break on them. I replaced mine with an AMS titanium test pipe

 

What makes it seem so weak that it cracks?
