Nope but please post a video when you are done. I want to hear what the H pipe sounds like. I like the X pipe but the H pipe should sound great

It's gonna be loud. Startups can wake the dead. So I run in full time stealth mode on the street. It sounded better stock.
And while people at the track seem to love the sound in Track mode I am not a big fan. It has that slapping sound that turns into a scream at high rpm. The H-pipe might be a good plan. If I had it to do over again I would go ported TB, ported stock manifold, ported heads, e85, 4.10 gears, and Rotofab. I might still do that.

I'll take a pic when I'm home of my setup. I honestly don't like the sound of my LT headers and H-pipe. It's way too raw sounding and unrefined, but it's probably because of the rest of the NPP system that make's it sound weird. I plan on getting an axle back to see if that changes anything, if not just going to buy a MBRP x-pipe.

I have the ARH 1 7/8" catless intermediate kit with the stock NPP. Found out this setup has the ARH x-pipe and the GM x-pipe. As said, everyone will know when the car goes thru the cold start up with in a 2 block area.
Going under a overpass in 1st gear and going WOT, deafening to anyone in the area. It is insanely loud when you are WOT. I had the GM x-pipe cut out today, so back down to one x-pipe in the system and then added the Hooker crush delete pipes I had in the attic. That toned it down, alot more than I expected to be honest. Called ARH today, I will have the pipe from the rear of the headers to in front of the muffler next week, while the current setup looks OK it is several pieces where the ARH pipes I ordered will be one piece stainless steel. |

o by the way to answer my own question. look at the pipes that came with the kit and measure off the hanger. then to line up the tips look at the last hanger with the 2 nuts and you will notice they are polished were the rubber was. just push it back until the polished part disappears and you should be lined up.
didnt get a video today maybe next weekend. with the valves closed and at cruise open wit ha mild2wild switch its pretty quiet but open and give it some gas and ya its loud.

I have the ARH long tubes connected to a Corsa X-Treme Axle back. Click my IG link below to hear the sound. Crazy loud but it’s sounds awesome—I literally get compliments every time I’m in the car.
