Duals....X pipe vs H pipe

X for days. All about the air flow on my 383

Hi, just went from an hpipe to xpipe this year. Xpipe is definitely higher pitch. As far as performance, hard to tell, since I did it over winter. Can't figure out how to add a link, but I did a thread on it with before and after clips.

Many times it comes down to fitment with the H-pipe being a little easier than an X-pipe, I made an H-pipe set up for my Monte.due to the size of the exhaust.

Nice set up 565bbchevy! I need to wrap my header collectors and fabricate a heat shield because they are within a couple inches of my NSS on the 4L80E. Any recommendations on which wrap to get?

I installed the 3" Hooker system with X pipe on my car last month. I guess I am putting performance before sound. Before this post I didn't know that an X and H pipe set up sounded that different. Haven't started it yet but hoping it's not too loud and doesn't resonate! I might be swapping out the straight through style mufflers that came with the kit.
