Just wondering which would be better on a True Dual system?? I will be running LT's, x or h pipe and Spiral Flow's or Flowtech mufflers...
I've seen more X pipes than H pipes...but I have seen just a couple H pipe setups...Whats the difference? Which would sound/perform better on a bigger cubic inch car?

H-pipe gives you a lower rumble.

X-pipe gives a higher pitched sound but a couple of more hp.

I've only seen LS1's with X-pipes, and no H's...I have seen a few H pipe LT1's, but very few..I just wondered.

I agree from what I've seen and heard. I havent really noticed a difference between the two sounds because of the way some poeple have there cars setup (long tubes, shorties, cams etc...). I have an X-pipe setup going on the car as soon as I can get to it.
