View Full Version : 4in or 6 in bends?

I'm up in the air about what I want to get to do the exhaust on my spirit and I'm not sure what bends I will need. I know the tighter bend is going to hamper flow some which isn't a big deal. I'm mainly looking for what will fit the best. Also I'm up in the air about either 2.5 or 3in The car will probably always be a DD but for the slight cost increase I'm looking at the 3in kit. Plus I'm sure I'll have parts left over for other projects so that's the way I'm leaning. So for those of you that have used the kits are 4in or 6in bends going to fit better?

Full 3" pipe (muffler yes, converter no) on my Shadow runs the same ET as an open 2.25" downpipe. :thumb:

Did you use a RS kit or is it a prebent setup?

Actually on the Shadow mentioned above, it is the old 3" off the Z which was actually bent by a muffler shop including typical muffler shop reduced cross section bends!

Ah, I'm thinking I'm going to order a 3in kit and use that on the spirit and use the left over pieced on the shadow ice racer. I'll have to get under there when I get home and measure things up to see what bends will fit the best.
