I'm gonna get the GTM MHI TT kit for my stock motor but don't know what exhaust I can have/must have for it. Neither do I know what down pipes I must choose.

All I know is that I like the Saclam exhaust best but no idea if suitable for a Turbo. No clue, no one runs that one
Is the 3" TDX Fast Intentions exhaust the definitive recommendation? It's ideal, not required. A true dual 2.5 will suffice at stock block power levels.
Are we talking dual 3" pipes or a single 3" pipe? Dual
Would 2.75" or 2.5" also be sufficient? Again, for which, dual or single pipe? 2.5 true dual will be fine.
And what about the downpipes? Size? what does it depend on, the diameter of the cat inlets/test pipes? Match your downpipe size to your exhaust size.

Thanks for advice
