What’s up everyone. I’ve been considering changing the muffler on my Borla adjustable catback, and just curious if anyone has done this?

Although I’m running no plate, I believe a good bit of exhaust flow still curves and goes through the muffler. The muffler that’s on these catbacks is pretty quite (comparing the muffler only, not catback as a whole). I would like it to be a touch louder, but also change the tone a bit. I’m not wanting to do an entire new exhaust, or go the cutout route. I’ve been looking at Borla’s 3 inch Atak crate muffler. It looks to be similar dimensions, and is also an offset inlet and center outlet like the original muffler. I’m just wondering if this would change much in the sound dept. I’m thinking that since their Atak mufflers are newer technology than when the adjustable catbacks were released for our cars, it may be a more unique/better sound. Any thoughts?

For what it’s worth, I’m currently running long tubes and ory with a mild cam setup.

Yes, it is already catless. I did forget to mention that there is a magnaflow bullit in the I-pipe. I didn’t add it to quite it down, but rather cut down on some of the rasp and clean up the sound. I know it won’t get much louder, but the Atak mufflers are louder than the pro xs (I think that’s what came on the catback) are. I’m also wondering if it will change the sound any...just something a little different that hasn’t been done. Who knows, might be worth a try.

It’s a custom fabbed y-pipe, and it’s got a pretty good merge already. It still had some rasp though. At some point I’m going to replace the headers & exhaust, but that will be down the road. I was just thinking of something minor to do now. I don’t want to drop the coin for new exhaust right now, I have other areas where that money could be used for.

That’s not a bad idea, I might give that a try. It would be cheaper too.
