Gibson spilt dual exhaust?

Does anyone have any first hand experience with the Gibson split dual exhaust for the JK regarding sound, performance? I have watched the youtube videos and a couple reference getting a headache at highway speeds, most likely from a droning. TIA

Performance wise, the JK exhausts aren't doing much. The only catback I've heard positive performance results from below 4K RPM's is MBRP. Otherwise, you're buying a sound and a look- Mark W.

Question

I am looking at getting this exhause and have some questions:
1) My Jeep is new (800miles) is it bad to change the exhaust soo soon?
2) Will it affect the engine negatively not having the stock exhaust?
3) Will it affect my warranty?
4) Will it change my MPGs?
5) Is it a good deal at $336 shipped?
6) Do you guys think it makes a difference between StainlessSteel or Aluminized, will one last longer or is it just about looks?
Thanks!

On our 10 Rubi I went with the Rugged Ridge cat back SS dual exhaust when I had about 1,500 miles on it. We decided to go with RR instead of Gibson because we didn't want it too loud. However, we used the Gibson slash cut tips. It was a better look. We did it strictly for the look and with it being a bit more loud my wife finds that she actually shifts it easier. I always had dual exhausts on all my vehicles and wanted it to be the same with the Rubi. Dual exhaust always looks good. To answer your questions: It's not a problem going with the cat back at anytime because it doesn't affect your warranty (after cat. conv.). It won't really help but it won't hurt anything either. It won't change your mpg's or give you more power. What you get with the 3.8, you get. Definately go with SS. Not only does it look great it will last a lot longer. Just like what was said, it looks and sounds better than stock. You really don't get any performance out of it. So far, everyone who has seen our Rubi likes the way it looks and the sound, it's just loud enough and no drone. More importantly, we like it. Together with an off road bumper it looks great.

Cool! Thanks for the info. Yeah I understand and dont care about getting more hp, I want it just for sound and looks. So the SS will last longer than the Alum? I just wonder if it is worth a few more $$$ to go SS.
Also did you do it yourself? I heard it is pretty simple, about a 2hr deal?

Like KiK, I've always had duals-

I went with Flowmaster 40 cat-back and SS, for longevity, it's kinda loud and I like that, also gets rid of that STUPID BIG MUFFLER at the rear--

It's KEWL

That does not look like SS. Is it just the tips that are SS? I was talking about the whole thing being SS or Alum. All the ones I look at come with SS tips, but the exhaust itself can be SS or Alum, will that affect the life if the whole thing is SS or Alum or does it just affect the looks?

Question

Like on here: 10 2010 Jeep Wrangler Exhaust System - Exhaust - AFE, Borla, Corsa, Gibson, Magnaflow, Rancho - PartsGeek the Gibson Alum is $337 vs $464 for the SS. What benefit do I get from the SS apart the looks?
Also the Corsa looks just like the Gibson, no?

The tips are SS and the pipe is Galvanized, it depends on where you live and the climate/salt/water-

I wouldn't want aluminum for my exhaust pipe-no reason and to hard for quick repairs-

Ahh, so basically I will get more life out of the SS and it'll be better/stronger quality?

It's worth paying more for SS, especially if you are anywhere near road salt. The whole system I have is SS and bolted on with no modifications. It's not difficult to do but I had a local shop where I've done business for a long time do it. I don't have a lift and I prefer not to do that type of work.

I had the Gibson SS dual outlet on my 2010 Sahara with hard top. The resonance inside was so bad that I had to take it off and go back to stock. It may be different with the soft top or top removed but it was just too annoying with the hard top on. The looks and construction was very good and it looked really good on the jeep, just couldn't stand the noise.

I don't know. I only heard it on you tube and there were others who mentioned about the "drone". We took a chance with rr. All I can tell you is that we're satisified with the rr system. We didn't want it to be too loud and did not want "drone" at highway speed. In my opinion, it doesn't have it. My wife didn't want it to be obnoxious. If it was it was coming off. We still have it on! I do think that Gibson makes a good system it just seemed a bit too loud for what we wanted; balancing the sound but still having duals. Good luck with your decision.

I think I might just wait and research a bit more. There is no rush anyways.
I found this:

Gibson and metal mulisha just joined up together, I've heard it's a pretty B.A. Exhaust. It's the Gibson split rear exhaust system with dual 5' tips, and it goes for pretty cheap, its not aluminized, looks good, sounds good, I really want the exhaust for mine

I have the Gibson. Personally i love it. I think it sounds great. Pretty loud and looks great. I installed it myself and found it to be very easy.

Just installed a gibson metal mulisha on my 2015 Rubicon. Seen a slight increase in performance between 2800- 3000 rpm's and a slight increase in fuel economy. I was tracking at 17.2 mpg around town and now have seen 18.6 mpg around town.

LOVE my db Performance by Corsa! It's a complete stainless steel axle back dual exhaust with polished stainless exhaust tips. I had it professionally installed and had the shop tech remove the resonator. Good rumble and definitely more noticeable after I had them remove it. NO DRONE! I do have a 10A Unlimited Rubicon with a hard top. I do hear the rumble inside, but mainly only when I stomp and hold onto the gas (i.e getting onto the highway). The interior rumble doesn't ruin a conversation with a guest in the passenger seat and probably equates to the already existing wind/road noise I had without the new exhaust. It was a bit pricey, but FREAKIN awesome and certainly one of my most favorite mods! Watch this guy's review of it from youtube: https://www.youtube.com/watch?v=oen9H7ZChGU

You'll hear it at 1:27. I know he also has an AIRAID CAI, but I swear mine sounds the same and I don't have a CAI. He also has this video of how it sounds on the highway: https://www.youtube.com/watch?v=klvB_PuPchg

Hope this helps!
