Perhaps 3" cat/cat-back was a tad too big on a stocker.
Went to the track tonight. Previous best was 16.400 @ 80.40. Good 60' on that one though, usually my mph would be about 81.xx.
I added the 3" catco cat and 3" force II catback and my best time was 16.374 @ 83.13.
I was pretty happy about the mph, but im still spinnin' pretty bad even when I only stall to 1k. I need to get the new rear in. Hopefully the 3.42s give me some more from the exhaust since I'll be in the high rpm range faster, which is where the exahust did help.
Headders would help, too
Just thought I'd share some times with ya'll.
