Exhaust back fire clank on accelerate. I'm stumped
I have american racing headers 3/4 with their o/r X. stock cat back pipes and flowmaster hush power axle backs.
I've had the set up for a long time for over 2 years with borla stingers. Never a problem !!! I switched the stingers to SLP loud mouths. After that this problem happened
When I am costing at 1500-3000 rpms and I hit the gas to accelerate agian the pipes clank and a huge POP noise arises. Like a poof every time i get back on the gas at any rpm. Even after shifting too
I added exhaust sealant to every clamp. That didn't help
Need help I'm ducking stumped
