Looks interesting, but I just bought a set of take offs annd the Pacesetter adapter for $303.00. Same HP claims, I know it'll fit like the factory and it's stainless steel. My recently sold cop car had a stainless exhaust from the factory, 203,000 miles and it's an 87. Still in great shape. Aluminized steel won't last like that. But if you need new cats anyway.... This might be a good deal. BUT! Looks like those cats are Catco high flow cats which are are not smog legal on OBDII cars in California. IF you live in CA you might want to verify this sytem is smog legal before you buy it, no info ont he website saying it is or isn;t. I went to pipe's website, no smog info there either.
