I did not use a kit, but I did have my single exhaust converted to duals with 40 series Flowmasters. SOUND GREAT. Ran about $300 for 2 Flows and 2-1/4" pipe from the manifold back, and Chevelle tips. Wouldn't use anything else...
1970 Chevelle 350
I ordered the flowmaster kit from jegs, it's around $280 with pipes, mufflers, hangers, clamps, and instructions, and installed it on my dad's 71 SS. Sounds great! I had to trim the front pipes about 8 inches (they make them longer for elky, sta wag, 4-dr, etc) but other than that it fit great. we'have had it for 3 years now, and it hasn't even started to rust. Can't beat it
I put the americam thunder kit on my 69 malibu and its sounds great. It took about 3hrs to put on, and i did it by myself in my garage with just jack stands. Only had to cut a little of the head pipes for the different size headers.
Does anyone have any information or experience on the potential to use any of these aftermarket exhaust systems (like Flowmaster)on later model cars, that have catalytic converters? Do the exhaust system manufactures make a product for a mid-70s Chevy? Is it feasible? Is it legal?
