exhaust X Pipe

[A1971Blazer]

My understanding is that an H pipe serves as a balance tube to even out the exhaust pulses from one bank to the other.
I'm not sure what effect it actually has but I did put one on my LS1 swap.

Since I used the QA1 coilover suspension, I have the exhaust dumping under the bed right in front of the axle.
It's a little tight trying to get it over the rear axle and in between the track bar and the rear mounted fuel tank.

I was worried that it would drone at cruising speed but it doesn't. It's actually fairly quiet until I step on the throttle.

I'm using the Borla stainless mufflers with 2½" stainless exhaust pipe and factory 2010 Camaro manifolds, with V-band clamps on all joints for easy removal.
