I read an old post about them, and the one member that did have them seems to no longer be a member here. So does anyone have the TPIS longtubes with the dual-cat y-pipe?

If so, how was the install?

How's the ground clearance?

How's the plug access?

Did you use OVC plug wires?

Where are the cats located at on the y-pipe?

Any pictures?

 

i had installed some not to long ago and they fit way better than the other LT on the market.... that is y u r paying so much for them. he had a stock wires clearance was good on a sportlined dropped Trans Am and plug acces was way easier... you also dont have to beat in the bottom of the car like u do in some cases with other LT headers. it is a bitchin lookin header too i am thinking about some

 

I have the TPIS long tubes minus the dual cat y-pipe. The ground clearance for the header is excellent, plug acess is great and an easy install. I had a custom ORY pipe built which helps maintain the great clearance. I can easily clear speed bumps and I'm lowered just over an inch. The cost was a up there but I think it was worth it.
