The title says it all. It is what I am in the middle of building. About 80% done with a mini tub to be able to tuck the back 315s when the bags empty.

Thinking ahead, what to do about exhaust. I currently go under the frame rails and this sucks at normal ride height. I don't want my exhaust to be my limiting factor when the bags empty. 3" pipes to a 4" mufflex.

I don't mind cutting up the car and welding whatever.

All I can think of is notching the frame and maybe using oval pipe for that section. And adding some reinforcement. SFC and 4 point (min) are "standard" for this build.

Any other ideas? I would prefer not cutting up the crossmember if possible. I was even considering just notching the entire floor! But that seems like a lot off work.

Motor is a 390 with a blow thru carb F1, if anyone is interested.

I made my own trans crossmember back in the day to tuck my custom made 3" ypipe up closer to the floor. I was running 2210s as well. Exhaust was 3" all the way.

I dont think there is a perfect answer for you on what to do about the exhaust. I would go with oval for sure but I think you need to determine how far down the car will sit when the bags are deflated.

I did a 4" cat back last year with 2 bullets ,over the rear axle and single outlet tucked up. Plenty of room in there too. But now am putting it up for sale due to adding twin turbos.

Just realized you were from Mass as well.

Hey Bottled: Yeah I agree, I guess if I had the air-ride first I could measure how much clearance I actually need when the bags are empty. Very good point. At this point I really have no idea what will be my limiting factor on drop. Might be TQ arm on my 12 bolt, or some other random thing I can't think of.

Good news is I have been in communication with Air-Ride Tech and they are eveloping a bag over strut setup for our cars. Rears can be purchased now. I am not buying the current setup they sell. So the bad news is I have to wait to figure this out.

I have plenty left to work on so there should be no issues there. Just sucks that I need to wait till I have the air-ride parts. Really no good way to know exhaust limitations without them.

Thanks again.

Hey Badass: Yeah, I had a dual 3" to single 4" over the axle and single out as well. But with the Spohn TQ arm, there is no where to go accept under the frame, unless I cut stuff up.

I really want a slammed look when it is parked so I think Bottled is right, I need to get the air ride first, then measure the space left and find a way to get the exhaust the fit that.

Cool that you are in MA. Not many Thirdgen guys are! Maybe when my build is done I will see you at some shows.
