I have a stock 97 12 valve. What would be the best downpipe for it? Also what would be some other good performance parts to put on it. Thanks.

 

I have a Banks 4" Power elbow and down pipe Ill let you have cheap or if you have anything you want to trade Im open.

 

I'd say skip the downpipe until you do a turbo or exhaust. Turbo-back exhaust comes with a downpipe anyway, and you will need an HX40 style pipe when you get a different turbo (depending on which one, of course).

Without a sig, I don't know what you have. But as a quick run down, get some gauges, do the KDP if its not been done, get or grind yourself a new fuel plate, tune up your AFC, and bump your timing up. Theres lots of info on each of these, just do a search.
