people with Spohn crossmembers, need exhaust help.

I have a car that im close to putting together. I dont know what im doing with the exhaust yet but i have a feeling that the spohn crossmember will be in the way of the header tubes when they get bolted up. The crossmsber is for a th350 conversion. Anyone have a similar set up, maybe with pics?

Re: people with Spohn crossmembers, need exhaust help.

Hope you don't plan on running true duals, because the crossmember hangs too low to make it possible. Sell the spohn and buy another brand, jegs, bmr, etc etc.

Re: people with Spohn crossmembers, need exhaust help.

Thats what it looks like. I do need to run duals, I need to know who has done it and how. I have a pretty good exhaust shop but would like to bring them a good idea or two.

I haven't seen anyone do it, look on the exhaust board, most people start cutting and hacking on the crossmember to get it done.

Re: people with Spohn crossmembers, need exhaust help.

my exhaust guy is the best. he really can get stuff in tight places. ive trimmed my spohn x member as well, to allow the pipes to tuck up a lil closer.
this is the best pic i have.
ground clearance isnt great, but i do not scrub over speedbumps at all.
m very happy with all my spohn products. if i wouldnt have bought this torque arm 5 years ago, id go with a shorty cross brace style.
exhaust routing is frustrating.

Re: people with Spohn crossmembers, need exhaust help.

I ran my 3" exhaust from my long tubes under or around spohns crossmember, and it was a pain in the but. I is almost the same as stage20s and it sure is low to the ground.

Re: people with Spohn crossmembers, need exhaust help.

I got my Spohn crossmember and said WFT! I am never going to have room for exhaust. I ended up cutting the factory subframe out and making new frame rails. Not I have dual 3" exhaust with tons or room!

Re: people with Spohn crossmembers, need exhaust help.

I have 3.5" true duals on my car with a spohn crossmember. Two slight bends off the header and a small clearance notch on the top side of the pipe. Notch in pipe only needed since my car sits pretty low. I have also put 3" on a friends car with with no issues. I don't have any good pics on the work comp of under the car. Here's the best I can do at work. I can take some better pics this weekend. Both cars are street driven with no issues.


Here's how low the car sits.

Re: people with Spohn crossmembers, need exhaust help.

I have the spohn with th350 and am running dual 3". I angled the exhaust to go under the crossmember at the highest point. It scraped like hell. So then I put a jack under with some wood and mushed the pipes a little. MMMMMMM Still scraped. I then put stiffer springs in the front, and tokiko adjustable shocks. The old shocks were blown to hell. I now have no problems no matter how fast I go down bumpy roads. Nice ride too. Havent hit any speed bumps yet. Car still isnt road legal.

Radial tire king your car gives me wood. I cant wait until the track opens up and I can take my new car.

Re: people with Spohn crossmembers, need exhaust help.

very nice exhaust work...i'm in this boat now..i want to run a true dual 3inch setup and i have no clearance under the car. If i run the pipes around the crossmember in best spot for maximum clearance i think i will only have 2-3 inches of clearance. I could live with that but i'm considering notching the frame for another 1 inch or so. Shouldnt cause too much structural damage..especially if i box it all back up with some plate steel and run subframe connectors, tieing it all together and then possibly a 8 point cage
