im debating between the bbk 1635 x-pipe which is a stamped chambered type of x-pipe, and the lethal performance or mac x-pipe which is a no kidding real x-pipe. i have longtubes and magnapacks, and I dont want it to sound like crap. when i had the l/t's, bbk 1635, and flowmasters, it sounded good but at half throttle it would pop... sounded like exhaust pulses bouncing off the back side of the chamber... didnt care for it. when i ran the l/t's with the bbk o/r h-pipe and magnapacks, it sounded like garbage. currently, i have a bbk catted x-pipe w/ magnapacks and it sounds good, but it isnt quite loud enough and my afr is at 10.3 at wot. so I want to go back to an off road pipe to get the afr's back up in the 11's and increase the noise level. I am afraid that if I get the bbk x-pipe it will pop again, but I am also afraid that the mac style will sound too much like an h-pipe. anyone have any input? thanks.
