cat bypass
I replaced my cat with a bypass and SW chip noticed some small gains , I am running a quite open exhaust Straight pipe with a 24" cherry so the noise was an issue, I did not change the mixture.Can some one describe a little better how to adjust the mixture . or is this a Porsche shop job?
I have since gone back to cat till I can work out better noise reduction.
Has any one used the car chemistry baffle plate systems?
Cheers
