Exhaust Whine?

[BurnzGTT]

Hi!

So, a few weeks ago, i excitedly towed my car to the tuner after finishing fitting the parts i had slowly amassed for my 34 GTT. While on the dyno Trent hit a bit of a road block. My cannon exhaust appeared to have the silencer welded into it, and was severly restricting flow and thus power. No dramas i thought, had a straight pipe at home, so the next day i went about fitting it. While it sounded great, i didnt like the look of just one 3" pipe, so i ordered some blast pipes. Once they arrived i went to the local exhaust shop and got them fitted. As i pulled out of the exhaust shop i gave it a kick in the guts and when in high revs it has a strange whine, almost like a bloody vacuum cleaner. Its extremely strange. I bolted the old exhaust on, and it went away. I have no idea what is causing it. Anyone run into this problem before? any advice is appreciated.

Thanks

Blast pipes = less muffling? I can't see the mystery.

I understand that, but my car sounds like a bloody vacuum cleaner.

Hahaha.

I also could not fathom a guess at why your car sounds like aids

[BurnzGTT]

Yeah its a straight pipe, with the blasties welded on the end. All well, just thought someone may have run into this before.

You might need to replace your muffler bearings.

lol

Is there a grease nipple on the exhaust? Might need lube.

[Skepticism]

Could be a hole somewhere and exhaust is whistling thru it

2 big ones on the end of the blast pipes.

Maybe post photo of said sweet pipes
