haha wtf? no it's not normal. check spark plugs and regular tune up stuff.

Weird tahts what i've always been told and have heard on each car i've seen.

wait, so this is normal? it doesnt sound bad i was just wondering.

Man. sorry it took me so long to reply, works been crazy.

The exhaust clip is also at a 600 rpm idle and the IC piping was not connected, so it revs really slow. When the pipes are hooked up, it goes to about 3K, then instantly to 7K. https://www.nopistons.com/forums/pub...#>/biggrin.png

I have a 3.5 inch from the turbo back to the rear axle where it Ys in to 2 2.5 inch pipes, then in to some EBay N1 style mufflers.

My new setup s a 4 inch from the turbo back to the axle, then in to 2 4 inch in/out mufflers, then 2 4 inch pipes out of the rear. Talk about flow. I dont think I will have a problem with back pressure. This setup is not on my car yet because I am waiting for my TO4R to come in.
