I recently installed Borla S-type Axle back exhaust on my 2013 GT. IT is loud, but I am wishing it was a little louder. I am regretting not buying the Borla ATACK.
Is there anything that I can add to my current set-up to get louder? Or do I need to buy a different exhaust set-up? Do the x pipes make a difference in sound? If so, what do you recommend?

Just looking for input. Thanks!

I'd start by either removing the resonators or getting an after-cat h-pipe... It shouldn't cost more than $50 to have the resonators removed at a muffler shop, and I think you can get the h-pipe for around $300 or so... I just put Roush axle backs on my '13 and I'm considering removing the resonators, I just don't want it to get any more raspy...

Xpipe will make it louder and make more power but you need a tune. That's my suggestion since you want it louder.

I removed my resonators on my gt500 axle back and it made 100% improvement. That's a good suggestion.

Give it a bit. They'll get alittle louder as they 'break-in'.

Changing out to the X-pipe will alter the pitch of the exhaust note. It's usually good for a couple horsepower. You DO NOT need a change to the tune for the X-pipe, it is downstream of the cats and has no effect on how the O2's control your air:fuel ratio.

Would a H pipe make it deeper than a X pipe?

I'm kinda curious if anyone else has noticed this;
My exhaust is stock except for Roush A/B. Under fairly heavy throttle they sounded raspy. But now that i'm running with a CAI and tune it sounds completely different. No more raspiness at all, just a deeper and way meaner roar.

Killed two birds with one stone I guess
