I have cordually decided to pull everyone's ATF trick. There are some things I don't quite understand about it. Mainly the "disconecting the negative lead on the ignition coil." Are you refering to the negative bat wires from negative position on the bat? And if not tell me where I need to be looking. I run a 89 GTU N/a and I am sure that helps .
Another thing I need to know is how much Hp gain would I recieve by a bonez high flow cat and an Apex N'1 single. Perhaps there are better muffler systems out there and I want to go loud but not overbearing. I am looking for a nice throaty roar. Well thanks for the help.
