hellion question

[slammed03]

I finished installing my hellion single turbo t-76 with no issues but after the test run I noticed the exhaust kinda back fires under deceleration and when excelerting (around 3k rpm) it makes a rattle noise. I tried tightening everything, anybody else have this issue, could the back fire be realated to it not being tuned yet?

You need a tune. My buddy had the rattling on his set up. It ended up being a pipe rubbing on the K member somewhere. An exhaust shop was able to fix it.

thanks for your reply i just noticed the cat back tail pipes are touching which would cause the rattle, so i guess after the tune the backfire should go away.
