I really like the dynatech headers and borla mufflers Ive got on mine. I basically bought the headers and a borla cat back and made a deal with the exhaust shop for them to trade me the single in dual out muffler it came with for a single in single out and then bought a second one. They used the catback parts to avoid doing a bunch of custom bending over the rear axle so all they had to do way run a two pipes back there with an x pipe between them and weld everything up. Sounds great. You can hear it when you get on it but its nice and quiet at cruise. My brother has a magnaflow cat back on his dodge and mine is quieter at cruise even though ive got real duals and headers. I'm glad I spent the extra money on the borlas. I was worried I was just paying for the name but I think they actually live up to their reputation.

Also I was considering cutting the cats of since they are so expensive to replace has anybody done that with this truck? Was there any affects to the truck after doing so? I know there would be a check engine light but can i get my edge custom tuned by gryphon to take care of that? Thanks for any help.

How did your truck act when the cat was clogged? Hesitation, jerky, and intake backfire? The reason I ask is my truck is not throwing codes by the check engine light flashed a 4 times. Ford said it could be clogged cats or a dirty Mass Air Flow Sensor. Or possibly the wrong spark plug from Auto Zone. Your feedback would be much appreciated.

I have a little over 80k miles on the truck. 88Racing My injectors went out and I had to replace them. I did it my self but I called the dealer and asked if there was anykind of warrenty on the injectors and he said no. Do you have anymore info on that?

my truck would not shift under full throttle you could hold it to the floor and it would not shift... But under normal driving it would shift fine. Also it would backfire and spark nock terrible. Also the passenger side exhaust the one that was clogged had hardley any air coming out of it....home this helps some oh and also bad gas milage.
