Any interest in a group buy on mid length header downpipe combos?

Anyone dyno their setup yet? I did...lost 3ft/lbs and gained 4hp, but it shifted the powerband to the left and fattened it up towards redline, so it feels much quicker. I also had a slipping clutch on the dyno this time around, and last time I was on the rollers I didn't. That may have contributed to the loss in tq.

from mine i get kind of a metallic rattle at idle or when the engine is under load
sometimes heat makes it go away but it sounds kinda poopy when i get on it but not floor it. sounds to be coming from actually inside the header or dp...somewhere in the exhaust.
the best way i can describe it is a cross between a metallic rattle or tick and an exhaust leak.
i suppose ill have to get under there and check it out
anyone else noticing this?

I have a leak as well now on mine, but I think I have the same problem as sick06cobalt in that something is not tightened properly. I am going to be taking it back to Midas this morning and see what they find.

Nah....it is just like D4u2s0t said in that it probably just needs to be retightened. Kind of hard for me to do it when it is -25C outside and snow everywhere.

I am taking mine to Midas tomorrow morning, they were too busy today to get me in to look at it. I will have my update for you then! Maybe when it is on the lift I can get some good underbody pictures!
