flowmaster 80 series or cut the exaust off at the cat
which do you think will sound better an 80 series or just let the exaust dump out at the cat. ive had 2 v8 fdodies with the exaust ending at the cat and i enjoyed it very much. im just at a crossroads here. i want the best sound possible and i wont get hassled for not having a muffler so thats not an issue.
just need some oppinions here
btw the motor is a 305 tpi all stock

Headers with a 3" y-pipe into a high flow cat then dump. Sounds pretty sweet on mine.

Its actualy illegal here because it doesn't exit behind the rear of the doors. I have a cat back system for it. It just sounds so nice I probaly won't put it on untill I get a call for emissions hehe.
