Ok, so I have been looking at swapping the exhaust on 70S back onto my 88 Cutlass, sounded so much better on it. I could put the less than 2" dual exhaust with 260 manifolds back on car. The Thornton shorty's will only bolt on to the driver's side. Either was Thornton shorties are $450 Canadian shipped plus $200 for down pipes. Or Hooker Comp headers ceramic coated are $800 CAD shipped. Only the rust quickly Flowtech or eBay stainless headers are the only affordable options.
