So I finally got around to completing my exhaust. Stock headers, delete primary, secondary and resonators. To an agency power cat back. I am extremely satified. Lots more low end power top end doesn't feel much different. The sound is definitely unique but it's rather quiet. My old C63 had a 2ndary and res delet. That was much louder than this....but the tone to my liking is much better. Gonna go to the track tomorrow night see what the difference is.

Sounded pretty good to me!

Good meeting you last night dude, and congrats for getting into the 11's!

Thanks man, was definitely nice meeting a fellow c63 owner.....yes guys I am very happy with gutting the primaries. I get a little bit of the header chatter from them but I picked up a tenth and almost 2mph from them.......but it was also a humid mid 70 degree night, so maybe I'll gain another tenth or so when the weather gets nice and cold. I'm gonna try and acquire a more aggressive tune and maybe run 100oct next time

Yeah, the DA was 1862 when we started, and 1436 by my last run. High for Atco. Normalized/corrected for DA, your run was 11.76@120.6mph. My last run would have been 11.6@121

Nice times. I went to the track Friday night. All I could get out of mine was a 12.95@ 108 with a 2.0 60ft. I don't think mine will run much better. Didn't matter if I was running a 12.9 or a 13.1, my trap speed was 108 mph.

Time for a tune

If I see 11.7 on my time slip I'll poop a purple twinkie, I'm gonna shoot for 11.5 this winter, CAN WE PLEASE GET A TRACK DAY GOING!

Good times, but sound is horrible from having no primaries. Invest in $ and get the whole system. IPE MBH/MHB, Agency power etc.

Johnny912

Actually the sound is really good. It's not as loud with headers, minimal chatter from the cats too

You haven't heard his car, how do you know. I thought it sounded great. Because, you know, I listened to it.
