Hey guy's newbe here and First I'd like to say Hi! Second I have used the search function I used to be on the Vehicross forum so I know how to search for answers to questions that seem to be common!
Anyways my ? is I have a 1989 Formula Firebird with the 305 with Dual Cats has anyone put SFC's with the Stock dual cats I can barely fit a finger between the rocker and the 2nd pipe and all the ones I seen at Summit racing when I went over ( I live just down the Road) seemed like they would never fit without Exhaust Mods. If it has been answered before and my search skills are rusty I apologize. Good informative site glad I found it!

shouldn't care about single or dual cats & are the only ones that actually tie into both the front & rear unibody subframes. The other SFCs tie into the rear LCA mounts.

 

Cool, Those look Perfect for me Just trying to strengthen up! I don't race or anything just weekend Cruiser but want to avoid future issues.

 

thats what i have.i bolted them in and then had them welded.they sometimes drag on speed bumps but it doesn't hurt anything.
