any problems with this working on my 93 formula ??
i don`t need a cat. will this be louder without a cat ??

 

Yes it will fit, but you will need to extend the pipe to meet up with your y-pipe(even if you had a cat, you would still need to extend it some) and you may need the newer style hangers (not sure). And yes, it will be louder without a cat. They are louder on LT1s vs LS1s in general

 

You will probably need some hangar work done, and you will need an S-pipe. They can be bought from SLP or your exhaust shop should be able to make you one. The loudmouth will be pretty nasty sounding with out a cat. Nasty as in crappy. In my opinion.

 

Yeah you will need the s-bend for it to meet up to your y-pipe

 

I didnt need any thing for my car, they just cut my I pipe and out the Lm in
