does anyone have an pictures of how much you cut off the subframe connector?

and do you think structural rigidity was compromised in any way?

does anyone know of a ypipe/sfc combo that is truely a plug and play deal with no cutting involved?

Thanks,
Mike

well, id rather not cut any off the frame... ill be using this car for SCCA road racing and frame rigidity is very important.

I want to do the same thing with my hotchkis SFCs (shorten the right side and weld it to the floor pan next to the cat) this may compromise how the SFCs help the car,but the "rigidity" of the shortened SFC should be the same,as long as it's cut and re-welded properly. the left one would be in solid and the right would be mounted in the rear where it should be,but 12" back from where it's supposed to be in the front. this shouldn't compromise too much,unless the shorter end is welded to a weaker part of the unibody than it would be if it was wher it was desighned to be. technically,the frame connector itself would be more rigid if it was shorter,but by the looks of these Hotchkis peices,I doubt they flex very much at full length.

 

Hey Florida Racer, I just made my own SFCs Saturday. I used 1X2X.110 CR1018 along the pinchwelds. I just bent the Y-pipe a little.

Are you going for A Sedan? If so you should run longtubes, then you shouldn't have any problems with SFC clearance.

I'm in Pines.

Sorry no pics.

I have my SFC put in when the car still had a single 3" exhaust system on it. The SFC were custom made and they just sectioned the SFC to go below the pipe.

Now there's no exhaust system but the SFC section is still there and as strong as ever. It just looks a little funny when you look under the car and the passenger side SFC has a jog in it instead of going straight back. The SFC are made out of 2 x 2 x 3/16" square steel pipe.
