Rated 5 out of 5 by from Sounds okay Them posting a video with aftermarket mufflers was kinda misleading as this x pipe makes a 5.0 with stock mufflers sound horrible, like a v6 with exhaust is exactly how it sounded. These probably sound awesome with aftermarket mufflers but with stock definitely not. Therefore, I cut out my mufflers and now my exhaust sounds pretty good. Took 5 days for 2 day shipping to get here. Also, know that the factory clamps are somewhat spring loaded so you gotta shove something in there to keep them from reclamping while sliding the x pipe in. Overall happy I bought this for around 90 bucks I couldn’t bare driving a quiet V8.

Rated 5 out of 5 by from Simple install This X pipe was super easy to install. With a 13mm and 15mm socket, it took all but 10 minutes to remove the stock car back off. Took another 5 mins to cut the old resonator off the stock pipe, and another 15-20 mins to mount everything back together. With the stock mufflers, the car has a little more rumble, and seems to rev a bit quicker, no drone, and a nice deep tone. I was sceptical that this would be a cheap part, and not fit due to the price, but the welds were great, and the fit was spot on. I recommend this 100%.

Rated 5 out of 5 by from Great pipe at a great price I bought this on the black Friday promotion for a bit over $80. Shipping was fast, and upon receipt, I cleaned...sanded...and VHT coated it black. Installation was simple. A sawsall or angle grinder makes easy work of the cutting process. My car sounds much better now. It's not obtrusive at low rpm, but it definitely has a lot more roar beyond 2K. I've noticed a slight improvement in throttle response as well. Don't hesitate to buy this x-pipe.

Rated 5 out of 5 by from Great bang for your buck I received this as a Christmas gift from my wife. The piece looks great and the fitment is equally as good. This took me all of 20 minutes to complete with jack stands. I currently have a muffler delete and the sound is amazing.

Rated 5 out of 5 by from Why pay more? After purchasing my gt I immediately knew I would make changes to the exhaust. That's what you're supposed to do with mustangs. Anyhow I saw the other resonator delete kit and was amused at the prices. I came across the cj mid pipe and jumped at the price. It does make the stock exhaust sound much better and installation is easy. Measure twice and cut once. I ended up purchasing a used axleback for a 2010 and having it modified for my 16. With the cj mid pipe and the American Thunder kit from Craigslist I'm out $200 for a full cat back system. Great deal, fast shipping.

Rated 5 out of 5 by from A must have for your Mustang GT. I was really surprised how much it opened up the exhaust to add this X pipe. I have the Borla ATAK axle back exhaust and it was pretty load before deleting the factory resonator. Once the X pipe was installed it really came alive. I can tell a difference in performance as well as it is extremely load with the ATAK mufflers. It sounds like a beast, little pops and a mean raspy sound when the car downshifts. No drone at highway speeds at all. When you get on it everyone stops and looks.

Rated 5 out of 5 by from Unbelievable Sound Ability My wife said she liked the sound of our 2014 Mustang GT, with the Roush Exhaust, better than our new Roush Stage 3 with Roush Exhaust as well. Then the first time my wife was standing outside the car as I accelerated past her, after I installed the X-Pipe on our car,she exclaimed that the sound actually scared her. :-)

I see the comment that this resonator delete will NOT work with active exhaust but do not understand why. Can you confirm that it will work? Thanks.

Getting a brand new 2018 Mustang GT in a month. Might need to pay an extra $2k for the extended warranty, but not sure yet. Q1: If I get this installed, does this effect the warranty void? Q2: Do you ship to APO? If so, how much for this item?

Asked by: rimchi01
I just bought a 19 gt 5.0 and thoroughly went through the warranty and jyst is, only when you modify lubricated parts aka the engine , like turbo , cams , or charger . Is the only thing that would void the warranty. Some things you can upgrade that are lubricated and the dealer will never know it's been done but be sure and tell the mechanic he must not put any of the hash Mark's with a paint pen on anything . Th that's how they will know , other than it sounding like it has a. Am or yo uh the obvious stuff like chargers or turbos you can modify all you want!

Hi will this still enable the active exhaust to function on 2018 gt 5.0

Asked by: Yule
This actually DOES effect the active exhaust. The passenger side expanded under heat in track mode and crimped the wiring into the bumper after installing it with what seemed like plenty of clearance. I installed it and cut exactly where I was told to per the directions on the site and video. This product will cause active exhaust failure on the passenger side. I am not a happy customer.

Hello guys, thank you very much for replying the question that I've asked you last week. I need to know if the X-pipe needs a tune after, I am a big fan of the angry V8 sound but I literally do not want to lose power! Thank you in advance! 

Asked by: Jay11
A tune is not required.

Does anybody know if this is compatable with the Corsa Extreme axle backs ?will the fitment work

Asked by: Crimson50h
CJPP Dave - what do you mean by "You will have a small segment of your factory piping that will connect the two pieces?"  Will I need to use an adapter to go from the XPIPE 2.5" pipe to the 3" Corsa exhaust system?
