| Ever wanted to get more performance out of your 96-99 5.7 Vortec Engine but don't want to go through the hassle of a long tube header install or an overpriced visit to the local muffler shop? Well here's your chance to get that extra horsepower without the headache. This is a stock direct bolt on dual catylatic converter that the stock converters have been cut out and new stainless high flow thunderbolts installed in there place. This setup will bolt right up to your existing exhaust manifolds or a pair of shorty headers without any modifications. All the stock o2 bungs are in place and ready for hookup. Converters were welded in by a certified welder using 309L tig rod so you don't have to worry about them rusting. The assembly was then smoke tested for any leaks and to top it off it was coated with 2000° header paint for longevity. The thunderbolt converters will come with a product warranty that high bidder will have to fill out and mail to the manufacturer A nice stock replacement from a auto parts store costs upwards of 400 bucks and magnaflow produces a high performance setup with high flow cats for upwards of 700 bucks. |
