SP Engineering will receive HKS's resonated mid pipe towards the end of January. We currently have 2 available for preorders!



PM or Call to place your orders!

bump for SP

 

this has become my favorite mid-pipe so far.

i think there is one left - gtm.

 

What is the price for the mid-pipe?
Thanks
p.s. in general what can you expect from this alone from a performance and sound point of view and how difficult is it to install?

 

you can expect a 20-30 hp and tq increase... this is due to the removal of the secondary cats and allows for about a 2psi increase.

everyone that gets any sort of y-pipe reports of stronger pulls, due to the increased boost. i'm still holding out until all the y-pipes are done. but this one is getting the best reviews so far.

as far as price, i forget about this one specifically, but they usually range from $600-$900.

 

how do you gain 2psi of boost from a loss in back pressure I can't wait to hear this explanation.

 

didn't think it needed explaining.

it's a fact. i'm not here to give classes...

if you don't own a gt-r, then i guess you don't really care. if you owned one, you'd know this already.

 

Hi jaspergtr,
I see you everywhere, lolz I'm debating on few Y pipes. HKS Resignated Mid Pipe is one of them, too.

 

It does need explaining because you are making a claim that does not seem possible
I do own a GT-R and I do have this mid-pipe in my car. I do not already know this information so could you please explain it to me?
Would you like pictures of it?

 

jasper where are you I want a response

 

lol! the hks legamax sounds heavenly. i make my rounds to disspell some of the myths. i found this site because of the wife's interest in 911's.
no pics needed. not many people would claim to own a gt-r, if they don't have one. (except a few trolls on the gt-r sites). it is pretty simple,though. take the pipe off your car, and look at your boost gauge. you should peak somewhere around 11.5 and taper off around 10.5 -10.
if you put the y-pipe on, you should notice a spike around 13 - 13.5 (some report 14), and a taper off around 12 - 11.5.
lol! i was at vir with about 20 other gt-r's for the east coast gt-r event.

wish you joined us... had a few guys from up north (nj, maryland, etc...).

 

I understand people are saying they report increased boost but I don't think that is true. Because less backpressure equals less boost, unless they tuned them at the same time
I originally signed up for the VIR even but I didn't realize it was 7 hours from me and I knew it was going to be below 40 degrees at this time of the year so not much as much grip to be offered as when its 75 and rubber on the track

 

do you know mc? he can give you first hand knowledge.

what were your stock boost levels?

 

So your just saying it because someone else did and you believed it? You don't know any actual reason why it would gain 2-3 psi? If your answer to both these questions is YES then back down now your wrong as I originally stated. If you want to continue to have this debate then explain why all other GTR midpipes don't have this boost gain or if they do explain why. Thanks for playing

 

you seem to be mistaken...

please don't assume.

i've seen this firsthand. i did not say that this was the only midpipe to give gains. please read. i'm all of the sudden doubting that you have this pipe on your gt-r. or else you would have almost the same results that every other person has, with almost every other y-pipe that eliminates the secondary cats...

if the turbo takes x% of exhaust gases, and that number increases as a whole, then x% also increases as a whole. come on, please use common sense. i thought you were kidding. even my 12 yr old knew this. you put bigger exhaust on turbo cars, you get gains. you reduce the obstruction, you pass more air. the more air you pass the more the turbos have to work with.

and i asked if knew mc, because he's pretty well-known within the community, and he and i have had many discussions about this.

do you know the diameter of the mid-pipe you supposedly have?
