Today I finally got my o/r xpipe installed from Mustangtuning.com! I got to help at the shop w/ the install and the fitment of the pipe was awesome! There were no problems at all with the fitment. After the pipe swap, we started the car up, no leaks at all. The quality of the pipe is great too, very very similar to the UPR Xpipe. Now what your all waiting for.....THE SOUND! I have Flowmaster 40's on the car (ya, i know ppl say its raspy!) and with the xpipe is sounds mean as hell. It finally sounds like the car has some nutzz. With just the Flows it sounded stuffy, but now it sounds very throaty and LOUD! At WOT, it is just scary, I think I scared alot of ppl as I was driving home. Everyone at the shop said it sounded very clean at WOT when I drove down the road to test it out. As for the gains, the car feels soo much better. It seems to pull more at 70mph and SOTP feels like I gained more tq. Its easier to spin the tires now from a dig and feels alot better!!! I will try and figure out how to post some clips I took of the new set up. I let my girlfriend drive and I took some video of her driving it w/ my digital camera so i will try and get those posted somehow (any suggestions appreciated!!) Thats it for now, sorry its so long but i know ppl were wondereing about the mustangtuning pipe. Oh ya, no MIL on yet either!! *fingers crossed*
