Is there any way to use this setup with 2013 Boss 302 without losing the quad side exhaust?

  • We do not offer a Boss side pipe compatible X-Pipe. We do offer a Boss side pipe compatible H-Pipe. Part number 11413410 (Off Road), 11413510 (Catted) .

Check Engine light If I installed this catted X-pipe with 1/ 7/8 LT KOOKS headers without PCM tuning will the check engine light fire up as the or it will not ?

NoNi Year: 2011 Model: GT

  • Yes, you will get a CEL but it won't damage anything. The rear O2 sensors are going to get an under efficiency reading so they will need to be turned off or a tune will need to be written to trim out the engine parameters so you run at efficiency level.

What kind of catback? So I have full long tube headers from kooks and z pipe from kooks. Should I buy a catback? I don't want any drone or want it too loud. Since the x pipe is a 3" does the stock catback fit? With Stock axle back, need advice please help thank you

09gt Year: 2012 Model: GT

  • Your stock catback will fit just fine into the x-pipe. The odds of having drone occur with your stock catback are slim to none since your stock catback is designed to keep noise at a bare minimum. As far as whether you should keep your stock catback, that's up to you. But to get the full effect of your investment into one of the best header/xpipe set ups on the market as far as performance, you should definitely do a catback, or at bare minimum an axleback. By doing this, you will be completing a smooth flow of air through your exhaust giving you the performance we all crave, but also give you the sound that you and your mustang deserve. I personally run the Corsa Extreme Axleback and cant say enough great things about it. I hope this helps.

    If you are looking to keep the cats in your exhaust system and really have that x-pipe sound that you're looking for, then this is the one for you. This is my second Kooks set up I have installed, one on a buddy's car and this one on mine and I wouldn't choose any other. It is a little pricey but you are paying for what you are getting. Makes the Coyote sound as it should.

    Excellent Catted X-Pipe

    I had the Kooks Off road X-pipe on and it was just to loud on start up for the apartment complex I live in. The Kooks catted x-pipe made it more docile and quiter on start up. But didn't ruin the exhaust note while driving, or taking it to redline. Only negative is that there is a potential that the cats may not work as efficient as the ecu requires and throw a DTC code of P0420 and P0430. I was told by Bama that some of the Kooks catted x-pipes work efficient enough and some do not. But with a quick tune change to turn of the rear O2 sensors, everything is great.

    Kooks

    This catted x-pipe looks great and delivers the sound your looking for and makes a nice note inside the car that wont drive you crazy of course it has to be paired with the Kooks headers so if thinking catbacks be careful with your choice. I know some dont like the drone so watch the cat-back issue and dont purchase a super aggressive system because it will be be super loud. AM have all the good products and this is a superior item.

    Great product for the most part

    Bought this to replace the cats on my '11 GT. BE AWARE: if you have Kooks long tube headers then you will only be able to use these pipes with the headers. Easy install and good fit. Overall quality is excellent. Only problem is I wish I could buy the catted legs by themselves with out getting a new x-pipe too. AM service is excellent. Pipes arrived two days after I placed my order. Will definitely buy from AM again.

    Took nearly a week to install

    I started working on it a week ago. Finally got it back together last night. Took over 20 hours of my time. You may think you have a full arrangement of tools but this will expose every tool you lack. You need every length extension there is in 1/4,3/8, and 1/2 inch. Every step fights you. Something as simple as reinstalling the starter. The top bolt was nearly impossible to tighten. I'd recommend to put the engine mount in place but install the starter before bolting it in. The a/c lines were in the way. The o2 sensor disconnect was difficult. I have small hands and barely could squeeze in there. Another tip: disconnect the front sensors before raising the engine.
