Should i make a dump out from the plastic fender or run a dump after the downpipe?
Electric cutout on either or manual cutout?
If i ran the dump out side the fender i wouldnt need a 3 inch downpipe correct?

If you have a decent exhaust, it won't run much, if any, better with a dump.

don't cut up your inner fender. running it off the downpipe won't do too much other than make some noise as the exhaust will try to go straight rather than turning and going out the dump.

Don;t know if it is still available but there was a "Jersey Style" downpipe..think it was TH....that had the dump at the end of the pipe and the exhaust went off the side. Three inch if you are into the mid 12s, I would say.

Save your money. Get a good quality exhaust and you wont need a dump.I bought my car basicaly as a stocker with minor bolt ons and a Hooker exhaust. Opening the dump never increased performance.
