N/A vs. FI exhaust
N/A vs. FI exhaust
lookin into getting an exhaust and was leaning towards the HKS hi power.
but, i want an exhaust that i can get now since i'm N/A, and i can keep for when i go FI. what should i look for in an exhaust that would make this possible?

JIC (or other brand) 3`` single does both (within reason)
From what I`ve gathered a 3`` (or 3.125`` aka 80 mm piping) probably does both. Many on here say that a 3``single is the max needed for an N/A car, so it must give a good amount of headroom for turbo power. In other words, if sinlge 80mm piping is borderline overkill for a 250/260/270 whp n/a Z, it might be plenty for up to a 350+ boosted Z. My 2 cents, but it seems logical. 450,500 + Z`s...probably need something special

Don't listen to anyone with something to sell unless they recommend something else, no disrespect meant toward anyone, just my experience. Your OEM exhaust is plenty good for NA, if you're planning on going FI in the future. There may be a system that's 'good enough' for both, but it's usually a compromise. Take the money you would have spent and put it toward a nice, light system for FI. I guarantee you won't be sorry.

I have an FI car, if you paid attention - with the FI exhaust system on it - and it works GREAT!!!
I only ask that the originator of this thread do some searching and more research, and not listen to other posters that do not give anything constructive.
And by the way - I don't usually just tell people to buy the FI exhaust - I consult them on options. In this case - it' does both VERY well.
Perhaps you should do some research and not bash other posters.

I still have plans for FI and I will be ordering the FastIntentions exhaust (metallic hfc + intimidator exhaust) in the next couple of weeks. The dual 2.5 will provide gains in NA and will not adversely affect your gains too badly for TT. I asked Sharif (ForgedInternals) specifically about this exhaust (which he does not sell) and he reviewed the website. Sharif will eventually get my business for an engine build and JWT-TT and he thought I might end up losing 25 max hp (or so) vs. a dual 3 in exhaust at the 500 whp level. This is acceptable to me. The FastIntentions exhaust looks like a great product for good flow that maintains low end torque (a lot of positive reviews and the manufacturer claims full 2.5" dual with H-pipe; dynos to back up claims posted by several).
My plan if the the exhaust is too restrictive at the top end with twin turbos is to install cut outs that open up at a certain rpm (if that can be tuned for). (That would provide for no back pressure at all post-turbo but still provide great low end torque before the turbo spools).

I don't know you, and I don't care if I ever do. My comment had nothing to do with you, but if you make it that way, I'd be glad to play along. Read my response carefully this time, and you will see that it WAS constructive toward the OP, and is probably supported by many members here. And if you thought that was bashing you need to lighten up.

Sorry if I offended YOU...

No problem, you didn't offend me, and I did not intend to offend you. I was only offering my opinion to the OP, and I even said 'no disrespect meant toward anyone', just so you would know it was NOT directed toward you.

and thats a good exhaust for N/A?? then why not the greddy TT 3" type as well?
i mean you want an exhaust that is good n/a and it good for a least 400 whp FI...if you build your engine then at that point get another one.
even the new injen ti is good for 396 whp and i think i ahve seen it higher in some other dyno graph
how about RSR?
With the 3" Trual Dual you lose a little bit of Torque down low and gain hp up top. Depending on how soon you are planning to go FI then I would just go ahead and get the correct supporting mods the first time around. Believe me it will be cheaper and less of a pain in the long run.

yah...defin... in any case.. you ahve those that migth choose single turbo look and they will need single exhaust liek JIC, or S/C cars which..well most n/a exhaust are fine...
I agree with you completly, i just dont think hardly anybody knows what they will do...everybody talks about FI, not many people do it
