Just mounted the exhaust up last night and on the test drive I noticed a thumping under the car when I left off the gas while in gear and also when I take a corner fast, do you guys think longer exhaust hangers(kartboy) would fix this problem?

 

more then likely its hitting the rear diff housing as alot of exhaust has this issue or is very close. extended hangers is a possible fix depending on there it touches. Try jacking up the car and check to see where its rubbing to determine if an extended hanger is needed.

 

Thanks for the advice, going to work on it Friday after work

 

Well it's not hitting anymore(still ordered kartboy hangers) I think what happened is that I used a little dish soap on the exhaust so it would slide easily into the hangers and the soap was to oily causing the exhaust to slide around in the hanger. Live and learn LOL
