Exhaust making a rattling sound
I just got my catback installed a few days ago and today I’ve been hearing a rattling type of noise. It sounds like a shopping cart being pushed. The noise only occurs when I have my foot on the gas. Besides that it doesn’t make the noise. The exhaust is an h pipe with a muffler delete design. Has anyone has this problem and if you did please let me know what you have done to fix the problem. Other then that every things fine and the exhaust sounds great.

Which company made the h-pipe and muffler delete design?
I have the Flowmaster scavenger x-pipe and the American Thunder NPP axleback. I hear a metallic rattling type of noise when I pull into a parking spot with cars next to me on both sides. It will happen for about 5 to 10 seconds, and then stop. I don't have it at a red light, a stop sign and/or while accelerating. Can't figure it out. All bolts are tight and no heat shields are loose. |

Hmm? I would need to listen to it via video or in person.

Check your rear most exhaust hangers, I have broken two of them and they rattled.

check and make sure that it is all tightened up, especially the hangers and any heat shields.

As someone who had copious amounts of rattles in my old MRT exhaust, sell it.
