I have always thought the new GT500 sounds awesome, and haven’t had much desire to alter the tone since I got the car. But recently I really started to wonder what these cars would sound like with an H-Pipe instead of the X. I had kicked around the idea of doing the traditional X-pipe resonator deletes, but they seem to magnify one of the characteristics of this cars exhaust note that I don’t care for, and that’s rasp. So, recently in a discussion here, Jmeo so kindly brought to my attention that Shifteck had an H-Pipe res delete option. I promptly ordered and everything went smooth with shipping. I had a few days off this week, so decided to tackle install. The pipe came with zero instructions, so I started the install following the steps I had seen in previous videos, but modified a bit because the length of this pipe was definitely shorter than the ones I’ve seen installed on YouTube. I thought things look a little off, but proceeded as I was committed to getting this thing on the car at this point. It’s a long story about what all went wrong, but essentially this pipe is the same diameter and the factory unit with no flaring on the rear to fit over the rear factory exhaust after you’ve cut out you factory X. My response from Shifteck was that this H-Pipe was supposed to be connected to the rear section with a butt type connection and wasn’t meant to be slipped over. I don’t see any way that would have worked, given how far back the cuts had to be made on the factory X to get behind the welds. As I seemed pretty much stuck with what I had and need to get the car mobilized, I sucked it up and went to my local exhaust shop, pipe in hand, to have some modifications made. They got me taken care of in no time, though I thought they may have taxed me a little hard for the work they did. But hey, I guess that‘s what I get for not catching the issues beforehand. So, I got home and finally was able to install this thing and WOW! I expected a slight change. But this thing sounds like all hell is breaking loose on startup and moderate load. It’s like a mix between 03 Cobra and GT350. It definitely has a throatier sound at idle and light load, and at WOT it just becomes a monster. I drove the car around for at least an hour on backroads, and man the shift snaps are magnified a lot now as well. After getting back home, all I could wonder is why the hell aren’t more of these running H-Pipes? Here’s the video. Forgive the camera. Don’t know what was up with the quality.
