replacement for corsa sport muffler

[johnk45]

Hello Ive had a corsa sport catback on my 14 6.2 for a few years and have loved it, but I recently installed longtubes with a catted y-pipe and it is obnoxiously loud. I'm just looking for the best replacement for it that wont be too loud. I know I'm not the only one that has ran into this, so hopefully someone can help out. Thanks!

If you want to spend the money you could buy gm's corsa cat back (touring muffler). It'll be a direct replacement for the corsa sport; no cutting, adding, welding. Or your could add a resonator/bullet muffler before the muffler.

 

There is a few aftermarket mufflers that could work (ex.borla xr1), but your options are limited because of the 3.5" pipe.

just hate to spend the money on another new corsa, but maybe i can find a used corsa touring for sale. I'm wondering how much that would quiet it down? I think for the time being I might put the resonator off my old exhaust on after the muffler so i wont have to cut much up, just wont have my tips on until i get a different muffler. I will most likely end up having a muffler shop fab up a magnaflow on it if i cant find a closer fit.

I was in the exact situation you are in except I did catless y pipe. I wanted to switch to the touring muffler, but they do not make a touring muffler for the 6.2. I even contacted Corsa directly to find out for sure. Corsa recommend adding a resonator. I did not want to cut or weld on a 1200 exhaust. I ended up taking the sport muffler out and adding a Flowmaster pro series muffler. Still loud but a little tamer than the sport. I sold my Sport muffler very quick on the for sale page. There isn't many options for a 3.5 center in center out muffler. I would like to go quieter, but for now it is better than it was.

Just curious, how much did you end up selling your sport muffler for? I will most likely be doing the same when i find a replacement.

GM does have the touring muffler, Corsa just doesn't have a touring muffler branded under their name... I've seen a video where a guy had arh/gm corsa. Sounded good, not too loud for normal driving and a monster at wot. I did ask corsa what they recommended to quiet it down a bit. They said add a resonator in front of the muffler, basically turns it into a touring muffler.

That's definitely impressive, there was a basic new Corsa sport muffler on here for sale on the other truck site. I offered 250 shipped,  and of course I got a no way. I seen the same exact person on eBay try to sell it . It sold for 210 plus 25 shipping.

Is the cat-back exhaust on the All Terrain X models the Corsa touring? I might be interested in a trade if that is the case, could use a little more sound.

yes

I have the gm performance exhaust , Corsa version, which is the touring. I have been wanting to try the spot muffler. I may be interested in trading. I have a 6.2 

[M1ck3y]

for a 2014+? Where are you located?

[02SOMWS6]

I should clarify, I have the GM catback as well and am also looking to trade for the sport. I have the 5.3L double cab, but I don't think that matters for just swapping the mufflers. I'm assuming touring and sport mufflers are the same size... 

 

Located in NY.
