Hey guys.
Again, just a BIG THANK YOU for all your inputs.
You know you guys have my utmost respect.

I got a custom catback exhuast system about a year ago.
Then I had my car lowered.
I've noticed a thudding noise from the rear when I go over bumpy roads and such, but even more so when I have a heavy load.
I couldn't figure out the problem.
Anyway... long story short...
The catback piping that bend over the stab bar is actully being hit by the bar when the car is weighed down and the roads are bumpy.

Just wondering if anybody else is having the problem.
I'm not sure if I need to contact the guy who did my exhuast, because I'm not sure he's a fault. I guess I'm thinking that even with stock piping, if a car is lowered the stab bar will hit the piping at some point. True?

I'd like to hear your comments.

Happy Happy Holidays!

 

same thing happened on my old I30. i had a 2.5" custom exhaust. it's a quik fix. all that he had to do was replace one of the bends by the axle. just ask the guy to redo the part above the axle
