Truck Pull Rules -- Exhaust Up and/or Down?

When reviewing rules for a local truck pull I noticed a couple things:

Exhaust must be up or down. I have dual exhaust that exits out behind the rear tires. This, I assume, is not acceptable? It's street legal. Any suggestions?

No aftermarket transmissions allowed. Wouldn't just about everyone with a built diesel have an aftermarket transmission?

Safegaurds built around U-joints and drive shaft.

Seems like a lot of work to enter a local truck pull and maybe walk away with a top prize of $150 and a plastic trophy.

Do they actually follow these guidelines?

If you are going into truck pulling with the notion that you are going to make money well.................

Some places follow rules, some don't.

well you wont ever win the money back that you have invested into your truck its just more for fun. I have seen guys just run like what you were talking about elbows of some kind and point them up or down. ive got a turndown that I run that is like whats on an rv to point it down if its required. yes most people have an aftermarket auto trans theres no stock trans that will hold brutal power and the abuse and weight of a sled. if I had a stock trans I would not even try to sled pull. having twin turbos you may want to just run at a county fair of some kind. the pulls with strict rules they will put you in an open class with twin turbos againist 1500hp trucks and you may not want that. some hot diesel classes allow twins just depends on where you are at. most county fair pulls they dont even check under the hood

No aftermarket transmissions allowed. Wouldn't just about everyone with a built diesel have an aftermarket transmission?Aftermarket meaning not available as a stock option... i.e, no Eaton 6 speed gearbangers. They couldn't possibly enforce no aftermarket components.

Safegaurds built around U-joints and drive shaft. You'll be thankful you have these when you drop a drive shaft at the 220 ft mark and it digs into the ground, or worse yet, bounces into the undercarriage of your truck...

As far as twins, several orgs are now allowing them with weight penalties(ex. you have to be 300 lbs under the class limit) and/or the atmospheric(bottom) turbo has to be within the regs for a single turbo in said class.
