Hey guys, I think I need to replace my axle back mufflers!
I did a lot researches and found GT500 and Roush I like most. Could you please give me some suggestions to help me decide? I would place my order tomorrow.
Thank you !

GT-500=quiet, civilized V8 sound with factory-fitment/durability and low cost
Roush=way louder, aggressive sound with crackling and popping on decel with higher cost.

Personally, I chose the GT-500s b/c I've had alot of loud cars and this is a DD. I wanted it to sound like a V8 but, not some snarling race car. The price point on the GT500s was a bonus but not the primary factor in my decision. Something was going on there and I'm happy with the choice I made.

Roush are great I get a lot of head turning and when cruising the interstate they settle down and you just hear a nice rumble they are also smaller than stock and bolt to existing mounting position.

I have GT500's with longtubes and Hpipe and I dont know where people say they are quiet? If you idle its quiet, but when you mash it it sounds like a racecar, and im not exaggerating, my opinion and ive heard both, if you like deep muscle car rumble and loud go with gt500's.....thats just me, and everyone comments on how nice it sounds and how loud it is.....!

I have Roush so I can't tell you you about any other exhaust. I can tell you that once I put these Roush cans on my car I fell in love with it all over again. I get compliments on the sound all the time and I wouldn't trade it for anything.

If u plan on doing axlebacks only for now, definitely Roush... Many ppl get GT500s to mellow down their full exhaust setups... Basically it keeps the exhaust from being obnoxiously loud... I myself have Borla S Type axlebacks and it's a glorious sound that I don't plan on changing anytime soon but their pricey $$ but u always get what u pay for IMHO

Do you have cats or not? That's a big factor.

GT500s are actually one of the louder setups when you get on it, according to a test latemodelrestoration did. In terms of decibels, it equaled flowmaster outlaws for loudness, although when cruising the 500s are very quiet. Unfortunately the Roush weren't part of the test, so it's hard to say actual decibel difference. But when people say the GT500s are quiet, I do agree because unless you're accelerating they aren't loud at all.

The first thing that went on my car was the axle backs. Of course I kept them but they are so mellow, I felt like papaw.
