I bought a mustangtuning o/r x pipe and i love it. I think its the same price as the UPR one. I think any X pipe in the 150-200 dollar range is gonna be about the same.
I picked up the UPR X pipe at a Ford show straight from UPR. I LOVE IT. good quality for the price and fantastic sound. I'm running a set of Ultra Flows and you can't beat the combination.
I have the Mustang Tuning O/R/X on my 04 gt....it was cheap and the quality is good...I still have the factory exhaust on it!!!....Sounds wicked!!...Everybody thinks I have Flowmaster on it....????
