Exhaust for a XL

[calima51]

Hi everyone,

I was interested in buying a corsa exhaust for my 2011 Yukon XL, but I have been reconsidering it. Because the car is so big, I doubt that I would be really getting that much of a horsepower boost. So that means I would be paying for only the sound of the corsa.

Does anyone have any suggestions/advice on just adding a muffler instead of the whole system?

I was thinking of a borla. Thanks for the help.

If you want more HP from an exhaust system, you will end up having to upgrade the entire system from the headers to the exhaust tip. Long tube headers and true duals will make a huge difference compared to a cat back system. If you do replace just the muffler or from the muffler on back, it will pretty much be only a better sound.

Do it out the side before the rear tire like mine lol. I noticed a pretty good power gain.

Replace the factory exhaust manifold with ARH 1 3/4" long tube headers and Y pipe. Use your factory muffler system.

You need to evaluate what your end goal is with your exhaust. Are you wanting more HP or more sound? To be honest, unless you do more stuff than just an exhaust your actual HP gains from an exhaust system on a stock motor are neglible at best. If I was you, I'd decide what sound you want by searching sound clips and go with that muffler or exhaust system. Then to get actual noticeable HP increases get a Black Bear tune and you will be good to go just my 2 cents

So you are saying you'll get more of a horsepower boost from Borla? Or am I reading it wrong?

Are you wanting a quality cat-back exhaust or are you looking for just a sound change?

No, I was saying that if I was just going for sound, I would just get a muffler. I am not too familiar with engine modifications and figured that there is not too much I can do to really feel an increase in power in the XL.

Ideally, I would like to see an increase, but will I feel it that much with a cat back exhaust? I don't know how much I will be able to spend on upgrades such as a big bear tune, headers, intake, etc. to make the truck have some real power.

Your feedback is greatly appreciated.

With a good cat back you will feel a notice in overall throttle response but that's about it. I would say that the best out there is probably a Corsa system but it is also a pricey item.

I do want both sound and hp gains, but I guess my question is how much of an increase will the corsa give me? The $1000 that is the reason for my hesitation. If it is only going to give me a minimum increase, then I would just go for sound.

Also, how much is a black bear tune?

OK. With that said, what muffler would you recommend? I really like the Corsa sound, especially the "no drone". I have three kids and I don't want it too loud. I have been looking at sound clips on youtube, for boral, magnaflow, and corsa. I really liked the corsa touring, even though it was just a hint above stock. Any recommendations?

Thanks in advance.

A black bear tune is about $500 or so but you get a significant performance increase from your vehicle and the majority of people notice a significant increase in MPG at the same time. You definitely get more 'bang for the buck' with that route. Many folks on here go the route of performance cold air intake ($200), mild exhaust upgrade ($300) and then the black bear tune and notice these significant gains with the overall package with the tune being the key to the 'package'. (dollar amounts are approximations and vary with brand and set up)

It mostly depends on your budget. Corsa is probably the best (or at least among the best) on the market but it also is $$$$. With regards to the drone issue many people like magnaflow (namely the larger muffler that is 22" long). I've also heard very good things about the MBRP system (sold on stylintrucks.com). In the past, i've always used flowmaster but they produce quite a bit of drone so when I do the Burb I will go either magnaflow or the mbrp system. You should PM Felixgun. He's got a nice setup with his magnaflow with volant tips and he says it produces no drone. He may have a part # for the muffler as well.

If you upgrade the whole exhaust system, the aftermarket piping you get will be close to the same diameter as the stock piping. Corsa's exhaust systems cost so much bc they don't sell the muffler separately and includes all new piping (Touring comes polished too not sure about sport... Which only adds to the price). If you are on a budget like me, all that is really needed (unless you are trying to do dual exhaust) is a resonator delete with some after market tips (in my case, I went with Volant's Super Tips) and a good muffler (Corsa (can't purchase separately)> Borla > Magnaflow... [best bang for your buck IMO]) with the stock 3" diameter piping and that along with a good CAI and BlackBear tune should get you right where you want to be. Also make note that the bigger the muffler the deeper/lower/less sound it will create which is why I went with the 22" Magnaflow 12589 muffler for the least amount of sound but has a deep low rumble to it (sounds good next to my friends Denali 6.2L).

great post Felix do you remember how much just your muffler was?

I really like your recommendation on the tune, intake, and magnaflow. It gives me the performance and the sound for the same price as a corsa touring. Is there any drone with the muffler?

Also, since I just bought the car, how does all of this effect my warranty. I was reading a couple of threads and was mainly concerned about the tune. What are your thoughts?

My previous NBS tahoe had the infamous drone with a dumped flowmaster muffler so I decided to switch to Magnaflow. No drone at all and I love it. The ECM/TCM can be configured back to stock if you purchase the AutoCal from blackbearperformance.com so dealership wouldn't even know you had a custom tune.

Felix...do you happen to have a sound clip of your setup?

Hi,
I would really like to hear what your setup sounds like. Also, you had mentioned in your previous post that Borla is better than Magnaflow. How come you didn't go with the Borla. How is the drone on a Borla? Could the volant tips reduce drone on any exhaust? Thanks.

Borla is more expensive is what it really boils down to. If I had expendable cash, I would've went with Corsa, then borla, then magnaflow (which is IMO the best 'bang for your buck'). The magnaflow muffler I can get goes for around 100-120 so it's definitely worth every penny.

Yea i'll try and post a video/sound clip as soon as I get some free time. I don't know about the drone on the borla bc i've never had one, nor do I think that it will drone. The drone will come from the type of muffler you get. The volant tips is purely cosmetic. Cutting the resonator off your car and changing the muffler are the two factors of how your exhaust will sound (aside from fully replacing the cat back/getting dual exhaust/other big performance mods).

Hi Felix,

Cutting off the resonator, is that illegal? Similar to removing the cat converter? I live in CA, so I was just wondering what I am getting into. I was looking at Borla, but it did not seem to be that much more than a magnaflow. I don't know if I am just looking at the wrong mufflers. I spoke to a muffler shop and they recommended the largest muffler for the sound that I wanted. He said the 22 inch magnaflow, which I believe is the size that you have. The largest Borla I saw was 19 inches. How does the size effect the sounds.
