IMO the stock manifolds arnt all that bad if you get the BD Fullbore replacment for the driverside. Been some interesting talk about that here and headers arnt anything to worry much about till the 1,000HP mark. On the other hand the stock up-pipes lack more than enough. I had been thinkin of makin my own, just a matter of time and money
If you have another car to drive just take 'em off and take them over to a good muffler shop. Find somebody whos interested... with that effort you'll hopefully find a guy who does nice work and gives a sh*t.
Not much to it really.
Money and busted knuckles could be spent with more result.
