wow that sounds really good, thats wat im lookin for. How much did that setup cost u?? Cant wait to see some videos while driving. Great setup man.
Spent $60 for 3ea Magnaflow j-bends, $200 for the stainless Flowmasters, $100 for the Magnaflow 4" muffler. The rest I scrounged from the shop. Cats were leftovers from a 3" BBK Ford Lightning exhaust kit, most of the 2.5" pipe was from 3 stock newer Mustang H pipes that are all 2.5". The 4" stainless was leftover from all the diesel exhaust kits(still have plenty of 4" leftover). Tips and flanges were off the stock G8 exhaust. I have a TIG welder and porta-band saw to put it all together.
$360 total investment.
If you can get your hands on newer Mustang "H" and "X" pipes from guys buying aftermarket, you can cut them up to fab up your own but it takes a little skill.
I am extremely impressed with how good it sounds, and just as impressed with the power gain. Never had a wheel spin problem until now, and on my marked off 1/4 it picked up 3-4 mph. I have a short driving clip but you can't hear anything with the window down for the first street. Then found out I was a little close on the cross member and it will touch under WOT. It should be fixed now but don't have time to record a new one...
