Benefit of going full 3" over stock exhaust piping?

When I get my MACs I was contemplating getting my whole exhaist done. 3 inch all the way back with my cutout.

Is it worth it or should I stick with my stock piping with cutout and hooker muffler. The local shop can do one up but it's crush bends. Is there a cat back I can install myself straight from the MAC y-pipe?

In general, going with 3" piping over the factory 2.75" sizing will promote better flow. Seeing that you already have a cutout in place, and assuming it is in the portion of the i-pipe right before the rear axle dump, I don't know how much more of a benefit the bigger piping will then be.

Yeah I'm thinking I'll just tget them to bend up an s pipe to connect my y pipe to the intermediate pipe.

should be no S pipe needed on the dual cat setup. the ypipe should end in the middle of the car. so run some 3" from the ypipe merge back to the 3" cutout, then stick with stock after that.

I have single cat headers for my dual cat car.. left that part out I think...

gotcha

search around...SLP use to make the S-pipe for their setups so that they are all interchangeable.

should still sell it.

probably work better than having a shop crush-bend up some POS.

or you could buy some 3" U-bent tubing and cut it to fit your application.
