Would you be willing to pay around 1500$ for an exhaust?

I don't think there are any true 3in exhausts except for the TurboXS. There's is not titanium, and is not much lighter than RB. You could try to find some titanium tips to try to make it look better though.

My main concern is I want LIGHT weight and 3" for future FI. My last concern would be looks.
The Exhaust is one of only a few places on the car to save a substatial amount of weight. So i will wait.

I had a friend with a certian titanium exhaust on his 8 and he lost around 3-5hp with it. I guess the lightweight factor kind of helps cancel that out though.

I was talking with a guy that owns a company that makes cat-back kits. Looks like we might take in my Rx and see about making a 2.5 and 3" exhaust system.
It would be from stainless steel or aluminized steel and we would also sell just the pipes so you could do what you want to them. They will all be mandrel bent.
Price would run from like 350$-450$
Reading around and asking questions I see alot of people care about weight alot. I dont think the exhaust would be super light. People want Proof! I want to prove if its gonna make any real power on a dyno. This would cost me about 210$ out of my pocket, 3 stock runs, 3 with the 2.5" and 3 with the 3".

Seems like alot of little things need to be factored in to something little like this if you really want it to work to it's fullest. I also get a feeling when the 3inch Y's off to 2 differant mufflers/pipes it could screw up the flow. I was thinking about just putting the car on the dyno with a strait pipe 2.5" and 3" to see what 1 will really flow better. Then see about using a 1in 2 out muffler, or 2 mufflers, I wouldn't want the Y and muffler to add so much extra pipe the air would slow down or stop in the mufflers. I'd like to keep it all the same speed if possable. We would still offer both systems for people that want to go FI, if the 3" out proforms we would just the scrap the 2.5". So much stuff, it kind of makes me want to not go through with the idea.

I'd like to target midrange to top, dont want to sacrifice any power just to add it to peak power.
I'll see.

I dont think in a N/A application you will see much gain from any exhaust. However in a FI application i think 3" will produce a significant gain ~8hp and more. RB did alot of testing on this and found not much there. Although the TurboXS system found more.

Well the end plan is for it to be a header back kit so it will produce real numbers.
The price would go up about 35-45% but I cant say for sure till we get some prices and some real numbers.

I will have the kit made reguardless for my car. Just have to see where it goes from that.

Actually, one poster on the board got a big hp, then when another one did the same setup, he got around 9 hp, exactly what RB stated you would get with midpipe & exhaust.

I am currently an FI'ed RX8, and I am thinking of swapping out my JIC titanium unit for the Turbo XS, as the JIC is 2.5", and my mechanic said the 3" would help quite a bit (not to mention a move from hi flow cat that I have on it right now to a midpipe).

If you have the money you can have a shop fabricate custom exhaust like TeamRX8 did.

I had the GReddy turbo with IntX and TurboXS exhaust and midpipe, and the power difference between that and my previous RB/RP Supercat combo was crazy. There had to have been at least a 30-40whp gain. I think another member dyno'd it and gained over 40whp. Its ugly as hell, but I can't express how much it helps with turbo'd cars.

have you tried to locate 3" Ti tube, let alone mandrel bends .... good luck

18 or 20 Ga T321 stainless is a better option cost vs weight

I highly recommend the HPC Extreme high-temp ceramic heat-barrier coating, it's great stuff

30-40 Hp gain seems pretty far fetched.
That cat must of been melted or something.

on a turboed car, it's really not that far fetched, less restrictive exhaust+turbo = big hp gain.

it will only work for a fraction of a second at 2000 degF before instantaneously vaporizing

Turbo is off, back to NA. The TurboXS exhaust tips are ugly as hell.

^ I'm sure you covered this in some thread but why did you get rid of the Turbo?
I agree with you, those tips are ugly!

The other side of the piping necks down to 2.5" :



And the exit out of the muffler is 2.5" :

I can understand the 2.5 out of the mufflers as there are 2 of thoughs but why would they neck down BEFORE the split to each muffler...its just a waste of 3" pipe!

I wasn't completely comfortable with it. It ran like a champ, but I don't want to have to worry about checking this and that, or something going out. I just want to hop in the car and drive. I didn't really boost very much anyway, so there was no point in me keeping it.
