I took the easy way out...muffler shop here we go. They did a great job. Actually, DT installed the header and Flowteck exhaust installed the 'Milteck' exhaust.
I still need to look into what to replace the exhaust on mine with... the 3" actually causes a loss in power plus the drone wears you out... will be doing that once I get these updates done.
So got it installed yesterday. So after an initial 25 mile drive my impressions are these.......throttle pickup seems to be a bit quicker and I can see a difference in acceleration. I can get to 60 a bit faster than before on a nice bit of road where before it would just hit close to 55. Sound is nice, a bit raspy at part throttle and lower rpm but sounds great at WOT and no drone at 2500-3500 rpm. Overall am very happy.
