Stock turbo/downpipe info needed
The kid who I bought my truck off of did a real hokey joke job with the exhaust, stock downpipe to the end of the cab, then a 4 inch adapter to some flexibend tube up to a giant bed stack. Kids these days.. Anyways I am redoing the whole exhaust to 4 inch turbo back, but need a little help. I have a 1989 with a stock turbo, when I look at Downpipes there are different flange options. So which one do I need?
