I have a set of the old boxed SFC's made for the SLP y pipe that I have yet to put on. I was wondering if anyone has these already installed can tell me, is there room where the catalytic convertor would be for a flowmaster 40 series to fit there without interfering with the SFC's? Thanks.

 

You won't have a clearance problem with the SFC's by putting in a muffler where the cat would be.

I just don't think the muffler would fit in that location because of everything else (body, transmission). Even if you did get make it work you would definitely be close to the ground.

 

someone on the board was telling me he did it on like 2 or 3 of his cars, said a 40 series 2 chamber and also the 1 chamber model fit there with no problems.....

 

Since you already have the SFC's, just jack up the car and take the measurements. You'll see what I mean about the SFC clearance when you look at the passenger SFC rail.
