A couple of weeks ago I finally got my exhaust redone. Cat-back custom with a Magnaflow muffler. I did mine the same way that mtbpath
did. I am sure there are others out there that have done the same.

With the new exhaust in place, I had to take it to the dragstrip to see what kinda gains I would get, if any... I put the K&N cold air intake kit on a couple of years ago and had practically no gain in my 1/4 mile times. I had hoped then that eliminating the restrictive "Y" before the muffler would be the secret to success.
See my 1/4 mile results from back then, on the 3rd page of my A/M air intake topic.
I must say I am pretty happy with the results!! My best time Friday night was a 15.08 @89.36. My previous best time, with only the K&N, was a 15.28 @89.52
I gained .20 in my ET.
A couple of things to note here...
1. I now have 50,000 more miles on my Pathy than I did 2 years ago, the last time I took it to the strip. I am now a firm
believer in synthetic oil!!
2. It was 15 degrees warmer this time than the last time.
FYI, I dropped the spare tire, took out the jack tools and any of my crap I carry around regularly. I did the same on all my previous trips.
Getting into the 14's wont be too difficult. I bet I would have been under 15 if it had been 45 degrees outside again. I could also let just about any friend race it for me and it would get into the 14's... most of my friends are much smaller than me.
