So I have an 91 GTA with the L98.

It has a 3in cat back with some sort of flowmaster muffler on it (40 or 44 i think. single in and out.)

I was planning on putting headers and the works on it but money just doesnt provide for it.

So my question to you all is what muffler would be louder/meaner than a 40 series flowmaster? I'd like to keep the 3 in piping that is already there and just weld in a new muffler and make a new exit pipe. The 40 series sounds good on take-off but it doesn't really have the volume/aggression I want. For reference I've been looking into single chamber mufflers and spintech mufflers.

I know a muffler wont make a huge difference in the exhaust sound but a muffler is all I can really afford. Thanks for any help in advance.

 

dynomax bullet is cheap and loud. straight through and very agressive. I have a flowmaster single chamber that is agressive as hell to. I am taking it off and selling it as it is too much for me. I have a turbo on my car and want something a little more stealth for it.
