    Awesome!

    Easy install. My 08 mustang gt had long tub headers when i bought it. Unsure of the brand of headers but x pipe installed just fine.

    Great quality and fitment, but you pay for it!

    Great product little pricey if you ask me for just some bent pipe. But went together well, use two people if you can to help hold while you tighten the clamps makes it alot faster. Had the other out and this in about 30 mins

    Great improvement!

    Had the catted x-pipe, but wanted to be louder. Mission accomplished! It's about the same at idle but really wakes up when you get on the throttle. I managed to to swap it out in an afternoon and on jack stands.

    Kooks long tubes o/r x

    Received two sets of bbk long tubes with I/r x pipe and the headers did not fit. Bolt wouldn't go through the flange and the x pipe was bent more problems but hard to explain on a computer. Bought kooks and had no problem at all. Fit perfect. Expensive but obviously worth it

    Well worth it

    I purchased this product because i wanted my car to have a little bit more horse power and louder. Both worked out very well. i had Corsa racing mufflers on it before and now i have Borla S type. It makes the car sound way nicer and meaner. I always get looks when driving because the vibration that comes out of the exhaust is awesome. I also have kooks long tube headers which makes the car even louder. It is a lot easier to install with long tube headers because the O2 sensors are closer, while with stock headers it is a annoying to unplug the O2 because it is on top of the transmission. all in all i totally recommend this product!
