i have a JIC TI 3 inch resonated version...my AAM Y PIPE is comming in later today..the y pipe goes from 2.5 to 3inches...i also have test pipes that i might put on that 2.5inches i beleive..

my question is since im NA will i lose power with this setup...will i be able to keep this setup when i go FI which will hopefully be within the next few months?will i gain from this setup still being NA?

im going to get it dynoed on the 2nd of next month so ill know then but yeah just wondering and welcome everyones input

 

The efficiency of the exhaust is equal to the MOST restrictive component. Put a bunch of 3 inch pipe together with a 2 inch pipe in the middle, and the 2 inch pipe is the chock point.

Besides if you want a free flowing exhaust why are you using a y-pipe?

 

you won't lose power. even with the test pipes you will gain a little. yes this combo is perfect for FI.

 

i don't understand this. he is replacing the factory ypipe with something bigger.

 

i was thinking the same thing..how am i not going to use a y pipe?lol

 

I think davidv is thinking of a true dual to have optimum "free-flow". Something like an x-pipe or h-pipe.

But who said that true duals have the best flow? IMO, the setup you have:
2.5" test pipes ----> 2.5" -- 3.0" ypipe ------> 3.0" single exhaust

is perfect for NA. So what made you think you would lose power? If this was a 3" true dual then I can understand power loss, but your setup is single which IMO is the best for NA power.

 

just wonderin if 3in would be alil too much for my NA setup as of now...i plan on going FI within the next few months...dont wanna lose what i just bought...most try to run 3 inches all the way back so yeah

 

so how do ya like the aam ypipe?

 

it felt smoother...my stock y pipe is 2.25in instead of a 2.5 so it definately had a smoother exit...alil louder but not too loud...still had that nice deep tone...i took the silencer out..it sounded like a honda with it on...havent put on the test pipes yet...might do it this weekend..looking to get a motordyne iso thermal spacer soon..then ill chill out and start saving alil more for FI..thinking about getting it tuned instead of dynoed next(i know tunning includes dyno)

 

i know it might seem dumb but if i was going to get it tuned id get a haltech in preparation for FI...seems smarter for me to spend a lil extra and not have to get another EMS later

 

lol if you can afford the haltech the by all means get it. but most people who are fi do just fine with the turboxs

 

That is smart but if you are plan to go FI in future, don't waste your time on tunning N/A bolts on. Getting ready for FI is good choice, haltech is one of best ems now in these days and i'm sure it will be in future as well.

Just tune bolts on is waste your money if you ask me. Trust me, just enjoy N/A with bolts on, and save money untill you are ready to go.

 

Btw, TP + AAM Y-pipe + JIC....it will be loud as hell...

 

lol thats why i sent him the silencer with the exhaust

 

i know it will be loud as hell...my setup is loud enough for me right now...im sure it will be too loud with the test pipes...maybe on a track day..idk..was thinking about high flow cats but hey thats more FI money...i would only go with berk

 

nah if you plan on going FI stick with test pipes. just keep the silencer in.

 

+1

If you going with Turbo, exhaust sounds will reduce little. And TP = Turbo. So you got TI? or ST? if you have TI, i heard TI = Turbo sounds sexy.

 

i got the TI...plan on getting a single turbo soon so yeah...so far all the cars that ive heard with testpipes have either sounded terrible or way too loud...im not trying to draw attention from 5blocks away..but then again i do have the silencer

 

hey, i was wondering if your happy with the JIC exhaust. i was planning on getting it since its a cheaper alternative to the HKS Hi-Power Exhaust

 

you can't go wrong with the jic. it's an awesome exhaust. im the one who sold it to him and i do miss it. but i like the agency power by far.
