I bought a Pro Chamber, sounded great, felt a definite difference. Then I do a 20 to 120 run one night and the thing starts rattling. Next thing I know the thing is coming apart. The welds are coming apart on the bottom of the chamber and then it starts to split down the sides. If this wasn't loud enough,the weld on the back of the chamber lets go. Nothing like having to drive the car with a gigantic exhaust leak and having it sound like I've stuffed a bunch of empty cans in there.
I get the shop I bought it from to get me another chamber from MAC, so I put it in yesterday morning. Then I decide to head out to the track last night. Makes 3 passes and the NEW chamber is making the same sounds as the 1st one did right before it started to split open. This is crap, now I get to try and either get my money back or a MAC H and some credit. This sux big time. MAC's quality is reaaaaaalllllllllyyyyyy dropping off big time.
You can see in the pic below where I had to have the first chamber welded up until the new one came in. The chamber was split open the exact length of the welds.
