exhaust info needed...

[SCM35A2]

I stole this pics from roalcoal & I was hoping to see if any of you had some info on it. I sent him a message, but its been October sense he's been active. My biggest question is what size pipe did he use, 5 or 6-inch and do you think any support brackets would need to be added to get it straight & from moving around too much?? Here are the pics...

I’m probably gonna take mine off. I used 4”.

That is 5 inch pipe. See the reducer on the bottom. Remember 4in pipe some places can bend. 5 inch you have to buy pre bend. They will be pricey. They still used the stock 4inch under cab pipe. You can run a complete new pipe from the turbo if you want more power from it

Thanks for the info bud, going to do some online pricing & after the holidays call one of the local semi truck repair shops to see what it will cost to run new/bigger exhaust pipe.

I would go full 5 inch back if you want to gain some performance out of the exhaust. You will have to modify the clamps for the upright section.
