Hey all,
I just installed a SLP cattedX on my 04 GT. For some reason I keep hearing this "rattle" or a vibration when ever i start off real slow (5 - 10mph) Then it seems to go away. Under hard accel, I can barely hear a trace of it. When the car is in park and i rev it up i dont hear anything, just the exhaust note. I checked and rechecked and there is nothing touching the car. All pipes are free from any moving parts. Could it be a leak and i justneed to re-tighten eveything? What do yall think? Thanks for your help!

In my case, I needed to re-tightena bolt on one of myexhaust hangers. Also might be that a hanger orsomething is loose,or needs re-welding.....

check your o2 sensors I installed an h pipe and I kept hearing a rattle and when I installed my stock h pipe back(it was too loud for me) I saw that one of my o2 sensors were loose so you might want to check that.

Jack It Up put it on jackstands and then check the pipe with a rubber mallet. Thats what we did on my boys 01 gt

Hey thanks for the ideas. The noise has since gone away so maybe the new x-pipe just had to "set in". Thanks for the replies though!

PS SLP is freakin LOUD!!! (LM1 & SLP X)
