Without being exhaustive:

Axle-back exhausts. Less money weaker sound quality.

Flowmaster #817600. Anemic sound at low, mid, high revs.

Borla S-Type. #11826. Quite deep tone at low and mid revs, anemic at high.

Borla ATAK #11827. Best axle-back. Interesting mix of sound characters. Good at low and high revs, anemic at mids.

Cat-back exhausts. Better choice for a better sound and more money.

Corsa #14466. X-pipe+chambered mufflers=very loud very raspy. Not bad, a matter of taste.

GT HAUS #?. Loudest SRT exhaust. The sound is very similar to the Corsa.
https://www.youtube.com/watch?v=bsfw8STXY-0

Kooks #?. Nothing extras. Not too loud not too quiet, maybe higher pitched. A little bit boring to me.

Stainless Works #JEEP64CB-S, #JEEP64CB-C. I don't know not enough informations. Maybe too much highs in sound.
https://www.youtube.com/watch?v=m95229-dJWk

Magnaflow #15064. The sound is strange like a V8 powered lawn mower. At least in the year of 2012. Nevertheless, this is my second favorite sound.

MRT #?. Last but not least. No resonator+H-pipe+deep tone mufflers=The BEST SRT sound I've ever heard!

Eh... Take his opinion with a grain of salt. I've owned both the Corsa system and now have the GTHaus, two completely different systems. I have yet to hear a system that doesn't drone... That includes the MRT. I like the ability to be loud when I want, but cutouts can do the same for less money. Budget and taste will your two biggest factors. Thomas did a lot of footwork for you by listing all the systems, just have to find some guys in your backyard that has a system that you can get some seat time in.

No problem! Find an online parts shop, like this. International shipping is possible.

@ Carbon6
I understand what you're saying.
I've owned both the Corsa system and now have the GTHaus, two completely different systems.
Likely that's right. But the difference in sound is less between Corsa and GTHaus than between other cat-back systems for Jeep SRT.

I've taken a dozen called with people complaining about the Corsa's drone being the worst and replaced them with everything from Gthaus to kooks and Magnaflow and each person was happy to get rid of the Corsa, Second most exhaust replaced was the Borla ATAk of just being a incomplete setup with not enough piping.

I used to have borla attack bcz I liked it from YouTube, sounds nice but still low, I saw magnaflow also in YouTube and didn't like it but I found it on eBay for 770$, so I decided to buy bcz it's cheap and full catback "not only rear section like borla attack". The sound of magnaflow is amazing and it's really different in real, I took video many times but really the video can't catch the right sound of magnaflow, it gives my SRT a European sport suv sound "Cayane turbo, Mercedes ML AMG or X5 Mpower". After magnaflow 0-100 timing reduced by 0.3 seconds. No drone in the cabin and I raise the RPM to 1000 and the sound on idle is amazing and all asking me about the exhaust.

Helpful thread, thanks guys. :thumbsup:

I am considering exhausts for my new 2015 so this is helpful. Definitely want the nice deep tones at low/mid/high revs with least amount of drone possible (Keep dreaming right??). I was considering GTHaus but going by this thread the magnaflow sounds like a good option.

What intake would you recommend pairing with the magnaflow??

Excuse my inexperience, what is the diablo and how does it work??

Cheers

I'm in the same boat having just picked up 2015 SRT. I have use Corsa on both my of W2k 5.7 in the past and was satisfied with the product for the most part. I thinking of going with MRT to try something different and I like the sound clips I've heard. I can't find anywhere pipe dimension for this kit

Does this help;

Description
The MRT cat-back exhaust system for the SRT Jeep Grand Cherokee is a one of a kind, hand crafted system that is a must have for those drivers looking to add a performance sound to their performance SUV. This 3 inch Mandrel Bent system is made of 304 Stainless Steel and carries an industry leading Limited Lifetime Warranty. It clamps directly in place of your factory exhaust system and can be installed in under an hour with correct tools. For the driver looking for the aggressive tone this SRT should have come with, this is the only way to go.

To keep the sinister look that the SRT offers, MRT also has a Matte Black finish available for the 4 inch exhaust tips. Cerakote is a high temperature, durable ceramic coating that offers a menacing look for your SRT and can withstand high-performance driving.

I put the AFE catback on a few weeks ago. Fit and finish is awesome. Sound is good. Much better than stock with a good tone to it. Although much better than stock, still too quiet for my taste. I had the AFE mufflers cut out and had a pair of small round Magnaflows welded in. Perfect.

First. Sorry for my poor English.
Second. Criticism. Because it seems need it.
If I want to be honest, then I say all exhausts is crap what I've heard on Jeep SRT. Yes, people say that is, this is the best... because they have no reference. That's the point! No have reference!(for the SRT) Maybe depend it from the taste? A little bit. But I don't know people why like the shit things. Folks! Why like you the raspy, rattle, annoying loud, cracked, hollow steel box sound exhausts?...
My opinion is that: build a good or don't do anything!
Ok. What is the solution? Very simple. Recipe of a dope sound exhaust which is devoid of any irritating sound.

1.) Pipes: 3 inch of course.
2.) Mid section: H-pipe or separate true duals. No X-pipe, no chambered resonator.
3.) Rear section. Straight through muffler with sound absorbing material. Important the exact size! If too big, sound will be muted, if too little, sound will be cracked. The good size approx: 3 inch core, 14 inch long body, 5 inch height and the shape is round or if oval then 5x8x14 inch.
4.) Optional if you're a perfectionist: Long tube headers.

Remark: Yes I know the X-pipe make better gas flow but almost kill the V8 burble, and creates higher pitched raspy note.

Two references(no Jeep SRT because no has Jeep SRT with awesome sound yet):
Firebird & Magnaflow: https://youtu.be/gEhgr7KPHok
Challenger & Zoomers: https://youtu.be/jK0OY7sAnZ8

SRT with true duals. The base conception is not bad however the mufflers are too small but it's not far from good: https://youtu.be/B-iLBFbewt8
