On 98 WS6 cars we have the single exhaust pipe exiting out the back, though they made cutouts for duals.
My question is does anyone have any idea why Pontiac went this way?
Was it just being cheap or was there some reason this was a good thing to do?
My friend that has a 94 Formula commented I was missing a tailpipe, I had to explain to him this was stock but had no reason as to why.
