Loudmouth Backfire Since i got my loudmouth installed almost a year ago when ever the exhaust is cold it seems back fires when i get of the gas. I say it only happens when the exhaust is cold because in the winter if the car is at full temp but i have had it off for like 30 min when i start it back up car is still at a decent temp but it backfires again. Also the car doesn't have to fully warm up for it to stop it seems to stop once the exhaust heats up. Any ideas? Its really annoying. Is this just a problem with the LM or will it do this no matter what exhaust i put on. i don't know if its an actual back fire it just makes a poping and gurgling noise.

Its sounds like just poping, I have LM too and it does it too, even more w/out the cats. Its just b/c there isnt a muffler or anything to provide resistance so it "pops" for somereason until it warms up. It can get anoying at times but I just love the sound of LM at WOT

I love the sound to, its just that my dad has been giving me a lot of **** about getting the poping fixed cause i wake him up in the morning when i leave for work. I also hate it cause i live right around the corner from Lincoln tech and the car is not usuaully warmed up by the time i get there and they are all standing out side to her me pop as i shift. But oh well. I beat any car they drive.

You have a hollow pipe for a muffler....stick a Borla XR-1 in there and the popping will go away. Will still sound good with headers, too.

That seems to be when it happens, I might just replace it with the Borla muffler
