Who makes 3" Offroad Pipes

I need a set of offroad pipes that go from stock manifold to 3" Cat-Back SW exhaust. I have found several that start 3" but go into 2.5" exhaust. I am doing a build with the Hellion Twin Turbo kit which puts the downpipe flange in the stock manifold location, stock size, and I have 3" Stainless Works Chambered Exhaust.
Thanks in advance for the help.

I don't know that anyone makes that, Most cars running stock manifolds won't really benefit from a 3" connection pipe. Unless you ordered the Stainless Works system with the performance connection your catback will also neck down to 2.5" to meet the factory connection as well.

I have the full 3" SW system, Looks like I will have to order tubing and make a set. I was hoping there was something out there I'm getting short on time.

Can't you just slip fit the connection? The difference will be negligible, seems like too much work for something with not a lot of payoff.

Might be worth it. 2.5in down pipes off of what im guessing are probably 62mm turbos isnt ideal. But also people have made big power with that hellion hit with just regualr cat delete pipes. 3 in could make a difference especially given the length.
