Flowmaster Outlaw VS American thunder
 

I cant decide between these two. i want the oldschool muscle sound and i want it to be loud enough to hear. will i get that with the American thunder? im afraid that the outlaw is going to be too raspy. thank you in advance for the replies! also its a stock ls3 if that helps.

I was looking at both of these and ended up going with Stainless works Retro chambered instead.. It was the best exhaust in my opinion and even better once I added headers.

that thread should allow you to hear all of them

i have at axleback for sale, pm me if interested

ive got the catback outlaw series and i love it its very deep and i love the exhaust note

I have the Outlaw catback too, and it is not raspy. It has popping on deceleration, but it sounds very deep at idle and part throttle and sounds awesome when you get on it.

Agreed. Liking the outlaws! :thumbup:

I've been leaning towards the outlaws and been watching clips endlessly on YouTube haha but I still can't make up my mind :/

I have the cat-back American Thunder system and love it!

there both good exhausts.

I think im going to go with the outlaws! im eventually going to get longtubes and a cai in the near future, but will that make it unbearably loud? I think the louder the better but I want it to sound good ya know?

Its pretty loud with LT'S. The catback by itself is loud

straight pipe, cheap and sounds badass

I'll let you know in a few weeks. I'm going to install my SP longtubes with highflow cats.
