Ok went to pick up my car from the shop after a week...Had Mac long tubes. Off road H-pipe and Mac cat back installed, also new poly motor mounts and sways and links...Also air pump delete done with every unwanted vac line and wiring gone ...My engine compartment actually looks like a normal engine bay now........Ok my fist impression of the exhaust sounds nice...Pretty loud but mellow at idle...My car sounds like it has a cam in it all because i lowered the idle down to like 800.... when you hit the gas its really loud...I love it......Question does Mac mufflers break in do they get louder??? will the exhaust quiet down a little in time once carbon builds up? The only problem he ran across is the steering arm hits the header so i need to buy a newer type joint shaft so it will clear better....any idea where i can get that?
