If you're keeping your engine NA then don't go larger than 2.25".

I decided to take the advice of a reputable and very good exhaust shop against the advice of some of the experienced YW members and I lost noticable torque. Had the shop re make a 2.25" and most of the torque came back and still has the increased top end.

That was with all the flow mods -dc header, MI intake manifold, intake, 1zz TB.

Ya mines getting boosties 😈 GT2860RS with custom tubular manifold and Haltech standalone. I'll post more on that as I progress. As for now I just have a closet full of parts just waiting on the money to purchase the rest of necessary parts.
Only reason I opted for 2.5"
