Forced Induction Finished Builds

I'd look at boosted performance on their turn as it's the easiest to install and comes with a good set of supporting mods. It requires you to have either a fast intentions exhaust or an exhaust where the midpipe location is exactly where the stock one is. He can also leave that part unfinished so you can take it to a shop and they can mate it to whatever exhaust you have. It requires a 6mt and available now.

GTM has a laundry list of choices. Their stage one garret kits are available and won't take long to get to your door. The mhi kit should be finishing up in the next month (don't quote me) and it's priced competitively with the BP kit.

Fast Intentions is super nice and more expensive, they also should start installing them soon. It's Def top quality.

VSR has a single top mount turbo kit they sell for around $8500 installed, but your car has to be shipped to them and that may prove difficult with you being in PR.

Also don't forget about superchargers! GTM really has that market cornered. I went and bout the twin supercharger kit. I'm pushing 550whp and the sc's have room to make a lot more. The stage 1.5s are really strong too. Lastly the stage 2's are a bit more expensive and have a bit more room for power than the 1.5's.

Start with a budget, add 50%, then figure out whether you want linear power from a SC or the sternum crushing mid range of a turbo.

Sorry to clutter this thread of eye popping FI builds with a noob question.
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.
Is the 3" TDX Fast Intentions exhaust the definitive recommendation?
Are we talking dual 3" pipes or a single 3" pipe?
Would 2.75" or 2.5" also be sufficient? Again, for which, dual or single pipe?
And what about the downpipes? Size? what does it depend on, the diameter of the cat inlets/test pipes?
For the sake of passing emissions I'd be going with cat but the rest of the exhaust all non-resonated to get the volume up as much as possible (cf. Saclam's racey sound).

Thanks for advice

For stock block power levels, a 2.5 exhaust and test pipes will work fine. It's not the ideal 3" downpipe/exhaust combo, but it's not a bottleneck at <500whp.

By "matching the down pipes to the exhaust" you mean matching the down pipes to the cats/TPs, right? I understand that after that there's still the X-pipe (true dual) or Y-pipe (single), after which comes the mid-pipe, ect.
I see many (catback) exhaust sold, starting from he mid-pipe onwards. That leaves the choice of X-/Y-pipe to me. And since the inlets of the Y-pipe will be smaller than the outlet, I do have to make sure the down-pipe-catalyser-combo mates to the Y-pipe inlet, but also the catback mating to the Y-pipe outlet, right? That is a lot of mixing and matching to deal with, no?
So which sections should ideally be 3"? all of them regardless of whether two pipes merge into one (single) or not (true dual)?

Chuck33079

Down pipes and test pipes are the same thing. All I was recommending was to keep the diameter consistent between the down pipes and car back. If you go with 3" down pipes and a 2.5" catback expect to have to take it somewhere to get the two to mate up.

Ok that clarifies things. Since test pipes replace cats, but I want to keep cats for emission pass, I cannot have downpipes then. or are they called "catted downpipes"?

Alkatraz

A 'catback' exhaust should be exactly that, from the cats back. Including the y-pipe. The MHI kit will bolt up to the stock cats or any aftermarket cats/tp's that sit in the stock location.

If you are sticking with the stock cats, then you just need to worry about which exhaust you like because having the turbo kit wont make any difference to fitment. I run the Fast Intentions 2.5" and couldn't be happier. The only reason to go 3" is if you want to go for more power than the stock block can handle (550hp+).


Edit: Should probably move this to a new thread V1H. Don't want to fill this one up with too much off topic.
