I spent last week hanging around Rockford Michigan with my car in Terry's shop. He installed my Quaife and MSDS headers (stock Y-pipe) so today I made a trip to the dyno to find out the news. The peak numbers aren't that great but below 5200 rpm there is a big difference in the numbers. I really think the stock y-pipe is killing the top end power but I won't know for sure until I change it out. I am going back to dyno again tomorrow to see if the Borla I installed tonight helps out. If someone could tell me how to post the graph I will try and get it scanned so everyone can see how it looks.
