Ive got a tip put on my ute and am having a bit of a problem with it, at higher revs there is a very noticable whistling sound coming through. A mate put it on for me and from what I can see he hasn't flanged the tip (tip was 2.5" entry) so there is a lip inside the exhaust pipe before the tip if that makes sense. I reckon that might be what's causing the noise but before I go to the trouble of cutting it off and getting him to do it again just wanted to see if anybody has had anything like this happen before.
Any ideas?

never had issues with mine and i had two of them at once. might have been an excess of decibels helping though.

I would be looking in other places mate, I'd be surprised if that's what's causing it.

if it is a single outlet rear muffler with a double tip then yep i have the similar problem of it sounding abit like that at high rpm, same thing before i added the tips it didnt make the noise. no idea why, but have booked the car in for its new stainless system with twin outlet rear muffler n comp headers so it should fix the problem right up :-P
