For those of you who have had experience with both, which ones do you like better? From video's I like the borla s better, which is what I have. But I'm really wanting to get the quad tip exhaust and valiance. I have never heard a gt500 axle back in person though. Coming from my borla s, will I be disappointed in the gt500 axle back sound in person?

Magnaflow has a quad tip axle back too. Sounds like carp though. But you could probably just order the tips from them and have then put on your borlas.

Gt500(which I have) sounds awesome but is also a lot quieter from what I've heard from my friends 5.0 that has borla. Once you get the other pieces of your exhaust the gt500 is amazing:)

Borla if you are gonna just stay with the axelback. GT500 if you are going to add anything else exhaust wise. Im running Roush right now but getting ready to go full exhaust with the addition of a off road mid pipe so I'm 99.9% sure I will be switching to the GT500s.

Uhm, tell me about it. I have roush axle backs and jba x pipe and cat deletes. It gets loud at 1000rpm. If I reallllllly baby it I can keep it quiet and accelerate but at how slow I have to go I might as well bought a Prius. I am debating what to do as I love the added power in removing the cats but the drone on the highway is insane.

My understanding was having even the high flow cats you still won't make the same power as having no cats. On this car anyway. Plus high flow cats are expensive and I have zero reason to have them.

Cats rob these cars. If you wanna keep that HP gain from not having cats switch to a GT500 (which sound awesome) or some Magnaflows.

Do they not have the heavy drone the roush do at low rpm?

I've never heard of the Roush axlebacks having drone. I had them on my car, and have no less than three friends with roush axlebacks on their cars, some with cats, some with offroad pipes.

3.73 gears once I hit about 65 on the highway if I am touching the gas they drone. Never had them drone before removing the cats. I still need to, since they have been on for a few days, retighten everything and make sure it is snug. Maybe I have a leak.
