So I've been looking at the prices for these two downpipes - why is the HKS one so much more than the JIC one?

I know the HKS one is 65mm which is about 2.6inch, and the JIC is 60mm which is about 2.4inch... will those 0.2 inches justify nearly $200?? Also, is the reason they make ~2.5 inch DP's to retain the torque, as opposed to using a 3 inch DP which would increase hp at the expense of torque?

 

Have you seen both up close yet?

The diamter will give quicker spool on the stock turbo...I ahve yet to see a JDM downpipe more than 2.6 inches

 

Nope, haven't seen them... is JIC intending on making a 2.6" DP anytime soon? I heard about either that or a 3", but I'm not sure.. I'd like to get a catback JIC but the place I wanna get it from currently does not have the HKS DP in stock..

 

We are a JIC dealer, and have the HKS downpipe in stock.......

 

How much are you selling the JIC catback with titanium exhaust for? and the HKS downpipe too, of course.

 

which cat back exactly?
the full ti, the half ti?

Email me..easier than talking on here

or you can hit me up on AIM at z1auto

well im sponsored by JIC and they have a 2.5 and a 3.0 coming out very soon i have to prototype 3 inch one on my car and all i can say is DAM! jic is the only way to go! top of the line look and just plain JDM power!

 

Hm, so have we dispersed the truth regarding 2.5" and 3.0" DP's yet? or is this just one of those things that'll never be solved

 

What do you mean truth? A full 3" gives better flow, and higher hp. The 2.5" dp will theoretically give you better torque down low, but sacrifices some hp up top. Hope that answers your question.

 

I just got my HKS downpipe in the mail from Z1 performance. Z1 has great service and is very fast compared to others i have delt with. The downpipe is beastly, top of the line guality with thick flanges and comes with a gasket to get a tight fit against the cat. I got a AMS catback on the way, hope that is as great quality as the HKS dp.

 

Awesome...glad it arrived so quickly!

zstryder - did you get my email last night?

Hey, yeah, I just checked it this morning.. anyway, I think maybe I'll hold out till JIC comes out with their new downpipe's and just buy them all at once.

 

Who currently makes a 3" ID DP?

 

How loud are the JIC Ti exhausts compared to others like RMR and Vishnu?

My personal favorite? Mache's high power front pipe. This unit is basically the downpipe AND turbo outlet constructed in one piece. 75mm (circa 3"), good enough for me.
