I just got done swapping in my Rb20 using the the R32 crossmember and hockey puck mounts. The steering knuckle is rubbing the dump pipe slightly and i was just wondering if there is any good aftermarket dump pipe that will clear the steering knuckle. I want a divorced dump but will take anything that will flow better. Any suggestions?

I found this. http://cgi.ebay.com/ebaymotors....m245

Common problem. I dont think there are any aftermarket pipes that clear. You can either notch it or switch mounts. Ive noticed mckinneys clear pretty well.

Syko elbow combined with a common SR20 downpipe clears just fine.

Will this line up with the rest of my exhaust if i use the syko and an sr20 downpipe? I just didnt think it would work with the r32 crossmember

It will work. The only difference is the turbo elbow. It has been modded to avoid interfering with steering. Otherwise it just fits to the rest of the exhaust.

Yes there is something for $325 from Australia but if you can do it custom it would be your best bet. Not only will it be cheaper but you will have it fit 100%.

ok i guess i'll just wait until i get a new turbo. No need in spending all that money now and then turning around and having to have another made. Im probably just gonna get the greddy mx downpipe to increase flow
