ok my 87 fc has one rusted out muffler and no muffler on the other side. if i were to put straight pipes in were the mufflers are like from the Y back and then a straight pipe were the cat is how loud would it be. like really loud or a growl type noise. or should i just stick with putting new mufflers on it? input would help

 

hmm well anyone want to help me out or not??

 

I wouldn't suggest it. You might get some negative attention from the local law. Your ears would be ringnig after a bit. I am contemplating what to do for my exhaust. I replaced the cats with a catco unit so I need some sort of catback. I will probably make my own custom system. I am not sure what mufflers I want to use. I want performance, but I want quiet. Sorry about jacking your thread. I'd put mufflers on it.

 

well i only have one muffler now the other is rusted off and it really isnt that loud. but what do you think about the cat would a straight pipe work?

 

listen to this... this is no cat or muffler and just a header

I've done it before. Its not bad. Take the cat out thow, holy hell, thats loud enough.

 

the reason the cat has to go is its all screwed up. theres leaks all through it and it is terribale so were just putting in a single peice of pipe in place of it.

 

wow that sounded awsome. i think what we want to do is a down pipe , remove cat and just high flow mufflers. what you guys think?

 

awesome but its ungodly loud and i got pulled over within 5 min of being on the road the first time i took it for a spin.... if you do just remove the cat it will have a nice sound to it especially if you have an aftermarket muffler... make sure the mufflers are packed with steel.... otherwise they will fail in a short amount of time from teh severe heat
