Roush Catback Exhaust

So I think I've finally narrowed down my exhaust choice to the roush catbacks from YouTube videos... If you have any other suggestions let me know but keep I'm mind it's a 2010 (4.6 L). My question is it if I get the catbacks will they eliminate my cats with them? Or does it bolt on behind my cats leaving them on? I was also curious about where an h-pipe or o/r x-pipe comes in in this situation. Would either one be beneficial? Thanks for the help!

Cat back just goes to the stock h pipe cats will stay on a aftermarket h pipe or x pipe come off road that has no cats but u can get catted ones that will have cats to pass emission tests.

I would go with the x its a more race car sound i perfer the x but everyone has a preference.

So then do I need the roush catback and an x pipe? That'll give it a deep race car sound even with high flow cats?

Do you have a 4.6? I just want it deep and have a loud nice idle. The videos on YouTube sound good but I want to make sure. I wish I could try it out before I committed...

I had the Borla catback on my 07gt and loved them! Best sounding setup IMO.

Re: Roush Catback Exhaust

The Roush axelbacks sound great and were a great price (when I got them) brand new. I would never buy them again though, I've had the car 1yr 9months just broke 4k,never seen rain and not a daily driver......the Roush are already rusting. There is no drone and they sound great but I'm unhappy with the fact that they are already rusting.

That is part of the reason I already recommend Borla. Yes they are expensive but they type of steel they use is top quality and will not rust, and they r&d they do is unmatched.

Do you have a video? I just want one that is deep, loud and has a nice idle. And you have your cats still on right?

That would bother me too. Do the axle backs sound good? Enough of a difference from the stock exhaust to notice? Mine is a 4.6 so unfortunately the sound is a bit different from the 5.0s. I wonder if roush makes it in a different metal.

Flowmaster Outlaws are deep. Deeper than Roush IMO. They're made similar to the Roush's. Any muffler you get that's stainless and welded with stainless will not rust.

Re: Roush Catback Exhaust

I ran Mac Boomtubes on my 05 & 07 GTs and loved them. The 07 had full Kooks exhaust with the Boomtubes and it was nasty mean. The Roush sound great and really scream when you get on them,I'm about to add ARH (LTs) and a off road X so it's gonna change alot.

So hard of a decision! The biggest thing I'm worried about is getting the right set up so I pass emissions and it's not too raspy...

Doesn't roush only sell the axleback? I remember looking for a fatback system when I was in the market for one and couldn't find one anywhere

Roush axle back are sweeet but i think they are made in china.... Not that its a bad thing cause a lot of things come out of china but there was a reason when i got them last summer for only $300 bucks brand new. Mine dont have rust but i oil spray them before i store for winter

The roush cat back system on stage 3 I think is in the ball park of 600 but I definitely don't want rust. I heard a video on YouTube that I liked a lot and that's what set me off on them.
