CA V1 header question

I got it installed by a shop and they did the pipe dent thing, but when i accelerate as it gets above 2k it starts to make this buzzing sound. It increases with the rpm and sounds kinda like a buzz with more air. is it just the better airflow of the header or should i get it checked out? i have a k&n sri and the v1 as mods. i havent installed the xtc header yet so im kinda lost on wut it is.

no takers?

oh it could also be were the dp connects to the exhaust, might need tightened all the way, i assume u got little springs to take place of the flex pipe and that could be the problem

two words bro. exhaust leak..u have it coming at the header flange to the stock downpipe. get that downpipe on and it will fix it. there is not much room on the two flanges for the gasket to sit properly and you will get a leak...when i put my downpipe on no more leak.

Most of my paint is off but w/e I like the metal look better anyway. And a decent DP should run around $200-$300 with a high flow cat.
