Pretty pleased with the sound with Pypes longtubes. My only complaint is that the mufflers get EXTREMELY hot on the dyno. much hotter then the rest of the exhaust system.

Sounds great with longtubes and high flow cats. I only had one issue with mine. The left side wouldn't slide far enough forward and was rubbing on the driveshaft guibo under near redline decel. I had to cut a very small amount off the back of the x-pipe so the pipe would clear the driveshaft better.

Could have been a install issue, no clue, it was on the car when I bought it. I couldn't come up with enough clearance though without trimming some pipe.

Sounds awesome though!

It's hard for me to say why that was the case without actually getting underneath your car but, I am glad to hear that you are happy with the sound of your system!
