I was hoping the sarcasm would translate...glad it did. LOLYeah the muffler delete is just for sound, the high flow cat would get more gains.
Yea...and a track elevation of 37 feet and DAs sometimes in the below Sea Level range...wow I'd love to run at that track!What I'm getting at is you can run low 13's with a tune and high cat if you can drive.
I ran all my times at Royal Purple Raceway in Baytown TX
My Grand Prix's 12.070 was ran at a DA of 5,500 feet! LOL
If you don't mind me asking, what were your 60's and are you Auto or Manual?
