I had the loudmouth exhaust on my old 94 Z. It was also an auto. It backfired sometimes as well. How does this exhaust sound on an ls1 with a 6 speed? Does it backfire a lot? I loved it on my lt1 but will it sound as loud or different on an ls1?

 

probably better......mine doesnt backfire that much......it does once in a while when it first starts up.....

 

A Good friend of mine has it on his 00 SS M6, and it has a very nice sound to it, nice and clean, and badass!

Mine does it just a tad when I first start it up in the mornings. But when warmed up, it's the best sound around.

 

yup sounds like loudmouth to me
