theres a used aftermarket header and downpipe for a chevy cobalt. this person had this on a non sc cobalt, which im assuming his is a non sc ss. this has a high flow 3" cat and a fronto2 sensor. hes selling it for $175. think its a good deal?

3 inch might be too much, reason he's probably selling it is because he's losing power having that big of piping

yeah i was thinking that too. but the miles are not 10,000 for that header/dp. my mistake. a guy who is selling a m62 eaton supercharger had 10,000 miles for $250. was thinking of supercharging instead of turbo

i would go with the supercharger, its safer, if you do go SC stick with 2.5in on the exhaust,. turbos can go larger
