Ok I hijacked some other stupid thread and decided to make my own lol. I was reading in the FI section and was pointed to PFsupercars.com by Alberto. They have a 4" single exhaust with no piks or vids However im very interested. Any 1 here running 4" exhaust?

IDC about the tq loss bc nitrous and other bolt ons compensate 4 that. I have the rear bumper delete so i think a angled exhaust like supras would look faptastic. Any thoughts? Besides power loss bc idfc

I say do it and report back with dynos, impressions, etc. If it works for 1.3L rotaries, 3L inline 6's and 3L v6's it would probably work well for boosted VQ's

 

I looked up the link you posted, sounds like a decent company-sounds
like they are similiar to the other fabricators out there(fast intentions and
aam) that take bulk materials and do all the layout work themselves and
assemble and sell to consumers from there, probably not a lot of R&D put into
it but use a layout similiar to other companies with a larger diameter piping
for improved flow.

i like the model they offer below-3 inch resonator system with no muffler-
has a warning message attached about waking the neighbors. recommended
for track use only with maximum weight savings.

 

I bet it would rock for a really pissed the **** off FI system.

 

+1 and

Edit: Subscribed, hopefully FI guys jump on this thread.

 

i think it could look real nice

 

... Maybe

 

I think a single 4" would be just what the doctor ordered for my setup...

This little disclaimer on their site had me rofling

 

4" > Duel 3"

(weight savings)

 

4'' loose a lot of power. You don't need no more than 3'' even with FI IMO

 

Before people start chiming in saying 2 pipes that are 2.5" = 5" , theoretically should make power, etc, etc, let me share my thoughts.

Ray's car is almost identical to my set-up power wise. Same turbo kit, he has slightly less aggressive cams, and I run 3" downpipes, he runs stock Greddy DP's.

While every car is different our cars make nearly identical power at all boost levels. I may make slightly more here and there but no doubt the 4" single works. I run a 3" TD. I'll ask him to post pics of it, Ive seen it under the car its a straight shot out....this could be another option for those wanting something different running higher boost levels.

 

fail

What is loose power btw? Does that mean I have tight power?

 

OK come on Webster. Its OK mama didn't hold you enough last night but whatever. LOSE sorry. 4'' is just ridiculous. There is no need to go that big unless you like that deep *** note it will give out, but also lose HP/torque. No need for anything bigger when it come to single exit 3'' is plenty. Even if your boosting 20psi(probably not ). For Christ sake my dads banks built diesel runs a 5" but boosts 35PSI or so.

 

Do you have data that supports the fact that a 4" single on built set-ups loses power? If you don't you have to see my point....

 

+1


There is a reason that Supra guys switch over to 4" after about 600whp or soo....

 

Not really lose. what I am trying to say is that you don't need anymore than a 3" on a VQ. If this is for a build race only then possibly 3.5-4" I dono This is just my knowledge. Maybe i'm wrong but this is my @ cents

 

Berto that would be fcking awesome if u could get sum kind of pik. I called and emailed and no response... Now 4 yall 2 know..... Im not ST yet. What my point is is that i now want a 4" single exhaust. I know the tq loss and idc bc i have that barry bonds. If the PF exhaust isnt angled then I will have 1 made. I just think a 4" angled exhaust on a lowered Z with the bump delete would not only look amazing but sound real deep and good. And the 4" exhaust battle 1 of my buddies with his Supra down here runs 4" boostlogic exhaust and made AMAZING power with it compared to his 3" HKS single.

Edit- just looked at sum exhaust on supras and I want mine way more angled

 

If you don't care about any loss then go for it and be different.! Titanium would look amazing also. hmmmmm all those nice welds make me droll!

 

Lets pray she come with the exhaust also.
