          First one I got the crossover pipe was the same size on both pieces. Could've been the same side pieces maybe? RETURNED! Second set is miles from fitting. Is it too late to return this?

          There was some fitment issues but nothing huge. Unfortunately package didn't come with the included bolts and I had to buy them myself. However the sound was great and got a good low rumble. Would recommend this to anyone looking to make their fox sound better.

          Had to cut flange corners off to get the holes to line up with header studs, the h pipe connection was at least 2 inches of center on one of the pipes, thinking it ws driver side. Had to eliminate the "h" completely and weld patches over the holes to make it fit. What a pain in the neck for a "bolt on h pipe" now I have mac straight pipes. Garbage. One star only because it makes you.

          Disapointed in MAC quality.

          First off let me say I have owned and worked on MANY 5.0 Fox body mustangs over the last 20 years. Installed many MAC brand exhaust systems because they are the preferred h pipe and this was by far the worst one I have seen. First, it was alumimized not even coated (all MAC exhausts I have seen or installed have either been HTS grey or black coated) so its probably started to rust by the time I walked in the house from the garage to write this review. Second, I had to cut the passenger transmission hanger right off because it was not even close to fitting in the trans hanger on the cross member, by like an inch! One good thing I can say is the driver side fit like a glove and there are no leaks.

          Works and fits

          good quality for the price.. Fit is decent i made a custom slip fit removable connection also modified collector area for smooth transition.. The headers are not custom made so the collectors are not formed and has the diamond in between the tubes and primary tube at the flange needed to be smoothed out and gasket matched .. Overall good .. My last set of long tubes i custom made and worked great that was a race engine this mac exhaust will b on mu street drivin mustang

          Expectation surpassed

          I have a 5.8 with MAC long tube headers in the front and MagnaFlows out the back. This H pipe was the missing piece I was hoping for. Exhaust note is amazing.

          Exhaust Upgrade

          I'm currently on my second 5.0 and on my first installed this same product and the perfomance increase aside from headers id like to say averaged around 7hp on the dyno and was definitely a good buy for the price, not only were the numbers attractive but the sound difference was amazing the beast in my mustang came alive ..i will now be buying this again for my second and recommend it to anyone considering performance or simply exhaust upgrades
