Super 44's

[tripps88]

Does anybody run super 44's with off road X and dumps? I had to do that on my car and a little above idle it sounds like someone is shaking a one gallon jug of glass marbles violently. Anybody had a similar problem?

See if the x/h pipe is touching the chassis anywhere, crossmember, etc or the mufflers for that matter.

I agree ^^^ my friends 4/6 car had full exh done..... one of the o2 sensors didn't get tightened all the way and rattled bad above idle .... his previous rattled too... found exh "rubbing" against the x-member.... hammer fixed that ....

I just had the exhaust done on the car. I know everything is tight against the body not touching but lets say btwn .75 and .5 inch all the way back. I wanted it tight against the car so it does not drag or hang lower than the rocker. Could it just be to close and would the pipes out the back help fix this problem?

I have not put o2's in yet, I have those holes plugged.

Thanks for those suggestions, any others?

My 95 GT did that when I put a fox body X pipe on it because the hangers were in the wrong position, knocked against the car but only at ~1700 rpm, any way you can get up under the truck while someone revs it to the "knocking point" and see what hitting?

Sounds like the exhaust... or spark knock haha
