C6 H-Pipe Owners??? X-Pipe Difference
My final mod to my exhaust is about to be complete I hope... I ordered a GM High Flow X-pipe Part Number: 19154781 from ebay and am curious what differences will I see. I noticed my car definitely pops alot after I installed a Z06 Dual Mode (W/ Muffler Mod). I figured by placing an X-pipe, I will get a cleaner exhaust note?
Thoughts?
I'm not looking into performance, just better sound...

The popping/ gurgling is still going to be there, x-pipe or h-pipe. It's coming from having the bi-mode valves open at low RPMS. Not that there's anything wrong with that. The x-pipe will definately change your exhaust tone (@ 6000 rpms it sounds like pure heaven). If you're buying it for sound alone it's a good buy. I personally like running x-pipes over h's.

I use the x-pipe with my npp. I never used the h pipe with it however. I can tell you that the pop and rumble will still be there if the valves are open. If you don't like the pop and gurgle add npp in a box. This will allow you to contol the valves as you see fit. When open it will sound nice and loud but when closed you won't hear a thing. Adding npp in a box was the best move I made along with the npp.

I changed from H to X, and really couldn't tell much difference. I'm sure there's a difference....just don't expect too much.

When I had my axle back mufflers and tips installed, I asked the installer, if a x-pipe would make a difference in sound and performance, he said only slight sound difference, and only performance gain would show on a dyno sheet, probably wouldnt notice driving. So I am holding off on buying one for now. They do look like the x would flow better??? Post up your feelings after install!!!

I was one who fell for this scam. According to people on this forum, I just had to get the x-pipe... what a bunch of BS. There's no difference in sound or performance. Just a lighter wallet. Tossed the x-pipe anyway when I got headers.

My experience with X pipes on two Corvettes, a C5 and a C6 Z06 is that the X pipe does change the sound, it mixes the left and right exhaust better, and it does sound more like an exotic, kinda 12 cylinder like. It's like you are hearing the 8 cylinders, but also the same, slightly delayed, or multiplied. It's like a higher frequency harmonic. It is slightly higher pitched than a H pipe car.
That being said, if that's all you are doing to the exhaust, I don't know if you'll hear much difference. Mine are headers, cat delete cars, and I drive the Z with the NPP open almost all the time.

I respectfully disagree. I just heard npp with the standard h-pipe on a buddy's car and then compared it to mine with the x-pipe and there is a difference. While it's not a HUGE difference it is significant with my car sounding "smoother". I couldn't find another word to describe it.

Ok. I got dooped. He sent me an H-pipe. The same one I already haave on my car. Now I have to send it back and I am losing money on this for shipping...

I had my doubts about switching after reading a lot of the threads and almost didn't do it. Deciding to try it anyway, with the idea that I could always change back and sell.
Well, the X-pipe went on this morning. Huge difference with reducing drone from the Magnaflows. I also don't hear the gurgle and pop as pronounced as with the H. Exhaust is still loud but now sounds so much more 'smoother' than before.
