Anyone have Flowmaster 80s?

How can I get them louder?

Cut a hole in it? Seriously though there isn't much you can do to make them louder. Do you have tail pipes coming off them or turn downs? Turn downs will reflect exhaust off the ground and make the sound louder. Get rid of your cat if you can and don't have inspection. Getting rid of the cat is probably the loudest way. If you really want loud then pull them off and run no muffler or glass packs.

I have the factory cat and the pipes dump behind the rear tires via slanted 3 inch chrome tips.

Sounds great tone wise. Nice and deep but just not loud enough. I may just swap out for a 40 series and sell the 80.

I plan to keep the 80's but remove the cat. I'm just worried about excess fumes at this point. Also, will I get a check engine light?
