I have a 05 Sedan AT. Bought a complete Megan Racing Exhaust system with resonated test pipes and y pipe.

I had an issue with the test pipes having so much flex that my y-pipe was litterally dragging on the ground. I eventually swapped back the stock cats and that solved the problem. No more sagging. Here is the damage. Car is lowered about 2 inches on BC Coils.

My review on the Ypipe and exhaust are great. Love the exhaust tone and the hp it gave me. I would recommend it to others but just not the resonated test pipe mating it to the Megan ypipe. Im in the works on sourcing a Berk hfc or Art pipes.

 

so that was the only tissue with the test pipes because im getting the v2 in a couple weeks
