yes. i have borla true dual exhaust. I bent the heat shield away from the cat but i think i bent it to much cause now there is a buzzing sound the is probably from the heat sheild hitting the frame. I dont know.

By removing the heat sheild completly did you experince any problems with the floor getting too hot. I heard thats not a good idea. Not sure.

well jaysens was welded, and the H pipe looked like it was welded slightly crooked, causing one of the cats to rattle against the heat shield.

yea it rattles sometimes but i think it might have to do with the install and not using the arm brace that supports the 2 cats. just a thought i had, but for the most part it doesnt bother me that much.

I found the problem. When we installed it me tweeked the exhaust alittle and caused it to hit against the rear bumper. We just adjust the exhaust and everthing is good now! Thanks for the advise guys!
