I just bought a new forte5 sxt. Looking to do some performance upgrades, a piece at a time. Im thinking the exhaust is first. Dont want the usual tin can junk, but having trouble findisomething specific for that year & make. Im also thinking of a cold air intake but hearing it pulls more hot air than cold and not worth it.....its a clean slate, starting fresh....thoughts???

My opinion is start with the CAI or SRI, the temp issue is just someone speculating as I doubt they actually did temp readings inside the wheel well. The main benefit from either of these is they eliminate the restrictions of the factory setup. Exhaust is fully custom at this point unless $1600 for a cat back from JunBL with very minimal gains is in your budget. Down pipe is available from Tork Motorsports and the CAI or SRI from 6th Element which either is a good place to start.

I also started with the CAI. It does not raise Temps at all. My Temps actually went down pretty good. You will notice it pulls and spools a lot better. For the exhaust you can do what you want. Our exhaust doesn't sound like a Honda so your good on that. Mine is straight pipe with no resonator and no muffler and is a bit loud but I always get compliments on it.

For mine in slowly opening up the airflow for the car to allow it to breath. I've got the cold air which is nice and a good sound :). The IC delete pipe is almost a need for good throttle response. Right now tho I'm currently working with about 2-3 shops for a good exhaust. Not sure if I want a resonator on it or just go straight. I like the way the car sounds just want it to sound a little meaner without being terribly loud (begets can't be choosers sometimes). Also I'm searching junk yards at the moment for the throttle body. (Air is key to power) l. After I get the exhaust I'll be getting the tune from Tork. Then after that I'll try the FMIC system (kind of waiting for a good system from 6th). In the meantime! I'm thinking of trying the hot pipe mod . Either making one myself or get one that I can just put on.

Happy hunting!

Thanks for the insight everyone I think ill save the money on the exhaust for now and srart with the CAI from 6th element. It sounds the most reasonable place to start for immediate gains. Keep you posted on the progress

If you do the CAI and the exhaust at the same time you will notice a big jump in power and much smoother. The CAI opens it to breath better and smooths out the powerband but the turbo needs to be able to push the exhaust out as fast as possible and the stock muffler doesn't allow it to do that. Get that muffler off and the gains will be that much more.

Jun bl makes a well crafted exhaust its running about 800 with shipping from Import Shark.com if you just want a fully stainless steel exhaust.. Jun bl is like the Greddy of Korea.. just understand a full exhaust for our car is a supporting mod.. much like A Front mount intercooler.. this part will not make a lot of power in stock form ( 9 hp).. but when you do a tune.. it will really help.. here is the link

Jun B.L Exhaust System, importshark.com

and here is a link for my build on all the basic parts and wrote up on the intake and supporting mods.. I have done so far

It actually does make a big difference when doing the exhaust even on stock tune. When I did mine I noticed the turbo spooling faster and pulling harder. Yes you will notice it more with a tune but even stock is a big difference from that really restrictive muffler. I found out from measuring that the stock midpipe is almost 2.5" but when it goes into the stock muffler it tapers down to 2" and to 2" tips. The muffler itself is a big restriction so that will help regardless of tune.

The Jun exhaust is nice but you can get a custom one for cheaper if you shop around. I got my muffler delete done with the Y pipe for $150 and sounds amazing and helped big time

Just to correct this The FMIC was an additional 22 WHP. Stock Koup A/T was 166 WHP and just the addition of the FMIC was 188 WHP. Last trip to the dyno with full 3" exhaust and DP, SRI, FMIC was 209 WHP all on the stock ECU. Please stop telling people that there is no gains or very minimal gains with a stock ECU unless you have bolted them on and been to the dyno yourself.

and I forgot the 60mm throttle body

22 hp from just an intercooler is impressive.. I would love to see your dyno sheet.. and your set up.. seems like good results.. you should do a build thread and show us your work.. I just have an intake and resonator delete and i'm making 182hp.. and when I was bone stock I was in the 173 range.. so 10 hp from an intake.. is about rite.. and the dyno numbers.. on the link I posted say about 10 hp form there product.. on a stock car... so what I what I said is correct too..

Also take into consideration that your a m/t to his a/t so your going to put down more stock.

US a/t guys get screwed a little more lol.

I think his numbers are great!!! I want to see his set up .. cold and hot pipe.. 22whp from an intercooler is awesome.. I think the auto cars.. are way better for track racing and drags.. you never need a driver mod.. one thing is always.. consistent.. the shifting..

^ We hold boost though and the AT is just as aggressively geared. It evens out which is why we are just as fast as the best manual drivers. All comes down to engagement. I like the AT on this car.

Yeah his numbers are awesome. If we do get those numbers from a fmic then one with my tune is going to do wonders lol

Its not that you can't gain power on the stock ecu, but eventually it will fight some of those mods. I think we all know a tune will get the most out of them.

It will fight once you have full bolt ons. Probably hit limp mode often or it will just retard timing and a few other things and give less hp

First the M/T will always achieve better numbers on the dyno over a A/T and numbers will also differ according to dyno (the reason I always go back to the same place). The dyno at Central Florida Turbo is a Mustang 4 wheel dyno which typically has a 6-8% lower WHP reading than say a Dynojet. I did have a build thread from everything done from day one with the car but when account was locked all dyno info, pictures and posts were deleted (username itsjustme). Since I was banned for some time I wasn't concerned with recording anything as far as dyno info goes. Everyone that knows me knows that I have no reason to say I have more or less than it actually is. The only thing I really have at this point is a picture of dyno results, data logs and a short video of being on the dyno of a pull where I was at 180 WHP with IATs @ 170°F. This was with a front mount but was getting bad sensor readings coming from the radiator fan blowing the heat against sensor.

What I took from what you said is any mods done will be very minimal "just understand a full exhaust for our car is a supporting mod.. much like A Front mount intercooler.. this part will not make a lot of power in stock form ( 9 hp).." is what I was replying to.

dude I want to see your set up.. a 22whp intercooler is killer.. show us your photos.. give us a parts list.. share your experience.. I don't take any offence.. to your post.. people like to start flame wars.. im not in to that.. show us your goods .. you had good results.. every one in the peanut gallery.. would like to see it too...

you are back put up your build thread again.. me and big k are swimming alone out here.. im doing the whats on the shelf.. you can bolt on.. big k is going the all out super build.. you should do yours

So are you saying I can just basically cut the muffler off and then just use 2.5" pipes from there and it will be a good gain? I might have misunderstood what you were saying on that.
