So..........The refining process continues.......But.....We are getting very close........When I did the car originally, I didn't know how to deal with the LS "Rappy" exhaust sound.........after getting the exhaust on the Impala during the initial build.........I had to go thru 3 sets of Mufflers to get the sound to go away and to quiet it down..........Ended up putting Cadillac Mufflers on it (Choke ,Choke).......since then I've learned that LS engines don't like long exhaust pipes (these go all the way back to the rear Bumper)..........and a "X" pipe helps kill the "Rappy" sound also.......
So....After finishing Gary's 65 and getting the exhaust completed with DynoMax Super Turbo Mufflers, an "X" pipe and tail pipes that exit behind the rear tires........His car sounded perfect........So.....I decided with last Winters mods to the Impala I needed to free up the Exhaust system.........It's going to the Exhaust shop on Monday for this "Correction" ....LOL.....I also bought a set of Headers off eBay that are supposed to fit........We will see........
