O/r tru x pipe
I received this x pipe in 3 days and installed them myself using a lift. It took me about an hour and god **** this exhaust is loud lol the car even felt a noticeable gain I have these paired with a magnaflow magnapack catback reall throaty and deep. sounds like raging elephants at 3000 rpm it's crazy. Just a word of advice u will need a flange for passenger side connecting to headers.Helpful (4)

Excelent product! Sounds great!
I recieved this o/r x-pipe for my 17th birthday from my dad and I couldn't be any happier. The sound is great; has that deep muscle car idle and a mean scream at throttle wide open even with the stock cat back exhaust. Matched with a bbk cold air intake I can feel the power beneath my foot especially between 3000 and 4500 rpms. Highly recommend it!Helpful (4)

A beast of a sound !
Simply amazing ! the air flow and volume is way better....it sounds amazing and doesent have a rhaspy sound. It fits right up to a stock system if you are just purchasing the x pipe. I went with bbk shorty headers, magnaflow tru x x pipe and magnaflow catback system. Magnaflow makes an AMAZING product, has a great sound, and added a huge h/p performance over my stock system.Helpful (5)

paired with magnaflow catback 04 cobra! amazing
couldnt have asked for a better fit, this tru-x replaced my bbk garbage x pipe and the quality right off the bat is much better. the rasp created from this x pipe is perfect right between 2-3k rpm. would definately suggest to buy it.Helpful (4)

This is by far the loudest exhaust system i have ever heard, when people on here say it will wake the dead there not lying. The best part is bama came through with a new custom tune to turn off O2 codes, no check engine light for me, but if your going to buy this get ready for tickets and a lot of smog. all and all very good product, would buy it again if i had to.Helpful (5)

I decided to purchase this X because I had Magnaflow Axel Backs already. I must say it's a great sounding combo! Above 2K RPM's it has that classic stang sound, that raspy eat your face growl. Personally, I don't consider this combo to be very loud. It's got a great tone and the volume is just perfect. When cruising in 5th gear you can barely hear it inside the cabin. When you step on it people definitely hear you coming. I purchased the MIL Eliminators along with the X and at approximately 90 Miles later, no engine lights. Great product American Muscle!!!Helpful (3)

I have a 03 Cobra, and this is my 2nd pipe, had the Summit brand, didn't fit was about 10" longer then the stock pipe, this was easy install took me less then 90 mins to take the stock pipe out and put this one in, was the exact same measurements as the stock one, bolted right in, didn't have to replace the flange studs, no leaks as well, good buy for a terminator.Helpful (4)

04 mustang gt will need 02 extentions on rear 02 scenors also gasket for header on passenger side
04 mustang will need o2 scencor extention on drivers side its about six inches too short. Also you will need to buy a gasket for the header to the x pipe on the passenger side. The install was very easy took less than a hour, The hard part was getting the bolts off the stock h pipe to the header NEEDED TO USE HEAT TO BREAK THEM LOOSE. American Muscle is the best very fast shipping and very good price i wouldnt buy my mustang parts anywhere else!!!!Helpful (3)

A Must Have
immediately felt performance increase and sounds absolutely nasty. highly recommendedHelpful (3)
Do I need O2 extensions with this x-pipe for my 2002 GT?
No but your probably going to need the mil eliminators if you go with the off road x-pipe.
Transmission? Is this compatible with either a manual or automatic transmission?
This X Pipe is designed for manual or automatic.
Does this work with a V6? I have a V6 that I'm putting a GT engine in, will this work for me?
With a 4.6L engine (like the 2003 GT), given that the pipes fit the frame of the undercarriage, this will work with your car.
O2 extension needed for my 04 mustang ? I have an 04 mustang gt and bought some magnaflow off-road x-pipe I'm going to install it with stock headers and was told that I was ganna need mil eliminators and o2 extensions ? Will the mil eliminators do the job to extend the space needed or will I have to purchase both mil eliminators and o2 extensions ?
My friend has a 04 GT as well, he needed both MIL eliminators and extenders when he installed his x pipe.
Horsepower gain ? How many horsepower will a magna flow x-pipe will it gain on 04 mustang gt ?
This x-pipe, by itself should net a 10-15 horsepower gain. Coupled with other mods, such as a CAI and a BAMA tune, you should expect anywhere from 25-30 hp.
No, this x pipe will not work with long tube headers. It will fit with shorty headers though. If you want longtubes you will need a matching 'shorty' midpipe.
The x pipe is widely known to produce more power on these cars than the h pipe. Just think of the way exhaust flows through both pipes and how much better and continuous the flow would be on the x pipe.
That's exactly what the MILs are intended to do. Due to removing your cats, the MIL eliminators will turn off the corresponding CEL! I highly recommend a custom tune down the road though as it will help you see the full potential of the mods on your Mustang!
Nope! The MIL eliminators turn off your CEL caused by installing an off-road mid-pipe. If you have a Bama tune that encompasses this mid-pipe, you wouldn't need to purchase the MILs.
