I'm thinking of picking up Kenny Brown's Dual-Cat SFC for my 89 Formula. The car has the stock exhaust on it right now, but I do want to eventually get headers, etc.

Can I install the SFCs before I get headers? Has anyone had any clearance problems with these SFCs and aftermarket headers?

 

I don't think the Kenny Brown SFC's will work with dual cat cars. I called them about a year ago to ask them and they said they didn't know.

 

I emailed Kenny Brown a while back and they said they had dual-cat versions of their SFCs. Kenny Brown, Spohn, and apparently Alston are the only companies I found that have SFCs for dual cat cars. (Not positive about Alston though... couldn't dig up very much info on them.)

I just want to know if I'm going to have problems down the road with headers if I install the Kenny Brown SFCs first. Has anyone had experience with them on dual-cat cars?

 

So no one has any info?
