Image uploaded by Jacob F. I have had my Bassani X Pipe for over a month now. I was apprehensive at first because I wasn't sure about the sound of the X pipe compared to the H. I must say I have no regrets. The install was pretty straight forward. I had no issues with fitment whatsoever. The pipe hangs slightly lower than the stock H pipe. I still haven't had any issues with it scraping anywhere and my Mustang is lowered. The sound is awesome. It is definitely louder than the stock exhaust, but has such a sweet note to it. It isn't overly done. It has a mean growl to it that wasn't there with the H-pipe. It also came with the cat deletes in the case that I ever wanted to go "off-road". It does open the exhaust flow up. LMR was the only place I could find this particular pipe for the automatic. If you are on the fence about it definitely pull the trigger on this X pipe. You won't regret it.

Yes, I would recommend this item to a friend!

I had recently installed a Borla Stinger cat back on my 2004 Mach 1. I was disappointed at how quiet it was with the factory H-Pipe. I purchased this X-Pipe along with new oxygen sensors and two 18" oxygen sensor extension cables.
The sound is amazing. It really woke up the cat back. The car now has a raspy sound and is about three times louder.

The X-Pipe was installed in my garage with the car on ramps. The install was fairly easy except for the passenger side front. The automatic transmission has a tube in the way of the collector bolts which makes the bolts difficult to get too. The rear oxygen sensors required extensions because the factory cables were not long enough. They were simple to install.

I would absolutely recommend this product.
