Wasn't a turbo whine after all

[Mike-in-Orange]

Since having my BTG cat/back duals installed a week ago I've been noticing this high pitched whine under hard acceleration. The sound was definitely coming from pretty far forward in the car but I couldn't be sure what it was. I called Maier at PT Tuning and he had me bring it by so he could take a look. We went for a spin and he said it was a sound he'd never quite heard before, but thought that I actually had an exhaust leak. As he thought about it, he guessed it might well be the new clamp they use where the BTG system connects just behind the cat. He sent me back up the road to his installer where they determined Maier was dead right. A quick touch up and everything is perfect. Maier and Zev at PT Tuning were extremely helpful and generous with their time. If you get an opportunity to do business with them, I highly recommend you do so.

I had trouble with that clamp also (I have BTG cat/back duals). When I installed it I thought I had that clamp tight but not so. Had to tighten it again. Really had to crank it down to get it to hold. Seemed odd to me that there is no hanger there. Wasn't one there on the stock system either.

They sound like they really do care(getting sued) about their products(reckless endangerment)and customer wellbeing(lawers)[8]

Could that joint be welded with better results??

The best thing to do would to be to get a nice stainless band clamp, like the stock exhaust has. You could drill the spot weld out and use the stock band clamp. It also won't crimp the pipe when you tighten it down. Just a thought.

If I'm not mistaken BTG recently switched to a band clamp and that's where the problem was. They did do a bit of welding to eliminate the problem and it's just fine. We took a drive up the coast over the weekend and all I heard was that sweet rumble from the duals.

I don't know what they call that clamp they supplied me, but it sure was not a band clamp. Anyway I am glad too see you are happy with your exhaust!

Like I said, I could be mistaken (sure wouldn't be the first time) but I do know that they just recently changed the clamp. The guys that installed mine, who happen to be PT Tuning's regular installers, mentioned that mine was the first they'd seen like this.
