I've had the TPIS longtubes for years but had a Y pipe made for them. The Y pipe I have sucks bad on multiple fronts and ground clearance is one of them.

How is the ground clearance on the TPIS Y pipe?
Does it mate up with a regular cat back?

Thanks in advance for any insight.

 

I have it on my LS1 Formula. The clearance blows. I have TPIS LT headers, and their y-pipe, and I think I have about 1.5" of clearance. Although, my car is also lowered about 1.5".
