I heard a stock LT1 last night with a Flowmaster catback with 40 series muffler. Is was insanly raspy and crackly and IMO sounded like ****. Is this really what they are supposed to sound like? I have 2OTL and it sounds 999999x times better I think.

 

I use to have the 80 series american thunder and it cracked and popped alot and sounded like **** compared to my gmmg.

 

I had a 40 Series American Thunder that crackled and popped. It rattled a little also. It's the way the Flowmasters are designed, one of the baffles rattles and gives it the crackling. It sounded like ****. I got a Dynomax Bullet, and that is nice and crisp.

 

My Borla does a lotta crackin, but I like the sound of it.

 

Unless your getting into the High End Flowmaster stuff, your gona be buying and hearing total ****. The Race Mufflers, ive heard are to be some of the best mufflers on the market. I have Xr1s.

 

I had the same one and it popped a lot when you let off suddenly.

 

I had a 40 series on my 93 and it sounds ok on acceleration but horrible on the decel...

 

The best way to fix the crapy exaust sound is to get LT's and ORY.
