I like a 60's era muscle car rumble such as a Ram Air IV Pontiac GTO, authoritive, low drone and violent when hammered down. I am currently building a car with a modern LS1 (motor will remain stock (2004 GTO) and putting it in a 69 Pontiac Firebird convertible. I am currently in need of exhaust for this build so your post is timely. I want to stay with a transverse muffler tucked up nicely between the mini tubs. I do not want something that is too loud to hold a conversation in the cabin of the car and absolutely do not want any annoying drone. I had to go with tubular headers, I prefered the factory cast iron manifolds that resembled cast iron headers of the 60's but clearance was an issue so I purchased Holley Black Heart mid length LS conversion headers in stainless. If you have any reccomendations I would appreciate it. Thank You.
