Question about downpipes

[dbacksfan]

This might sound like a stupid question but I was wondering "What part is actually the downpipe?" The reason I ask this is because Corksport shows a short pipe that is coming directly off of the turbo and looks to mount up to the part that Apex and Protosport are calling their downpipe. Both of these parts are referred to as downpipes on their companys respective websites. Which part makes a larger whp gain? Also, is the pipe that Apex and Protosport are selling the middle piece between the turbo and the muffler? Thanks.

This might sound like a stupid question but I was wondering "What part is actually the downpipe and which one makes?" The reason I ask this is because Corksport shows a short pipe that is coming directly off of the turbo and looks to mount up to the part that Apex and Protosport are calling their downpipe.

A true downpipe will be the immediate discharge housing. In other words the inlet of the turbo and then the outlet. (in lamens terms) the outlet peice whether it be a cast housing that incorporates your Wastegate flapper or just a bolted flange with exhaust pipe.

the pipe that Apex/prosport and any one els is selling they call it dp, that will give you most gains since it gets rid of the cats, geting the dp and catback will give you most gains

yeah what corksport shows IS the downpipe, though most of us here refer to it as the "s-pipe" for obvious reasons. technically, what apex and protosport are selling is a midpipe, but most of us just call it a downpipe just cause. and fyi, ion's turboback replaces both the stock midpipe and downpipe. when i have my downpipe made, it will be a true downpipe, plus the midpipe section with 1 hiflow cat.

btw hukster, who's that in your avatar? she's really cute . looks like ayumi hamasaki.

yep you right , gess every one has their own japanese idol

and take some pix of youre full dp i wona see how it will end up looking

 

[dbacksfan]

Thanks. That makes perfect sense. When I was looking at it I thought the Apex pipe was actually the midpipe. Does anyone know what kind of whp to expect out of the Apex with highflow cat. Just curious.

I've heard 5-7 WHP but I don't think anyone has dynoed it yet.

The one without a cat nets you 10-12HP.

 

[hukster00]

any one dyno that one yet ?

 

[Striker187]

yeah, ayumi's seriously cute though . i have one of her cds. she also won best artist at the japan tv awards.

haha, don't hold your breath for the pics. still saving up the money for the dp. but not to worry, i'll take pics of everything i can .

 

[hukster00]

ye, hehe i think she has won like 4 times in a row , you shoud listen to her eurobeat cd's mad good

good luck with the dp, msp has omost no space to work on

 

[Striker187]

the shop that's gonna make it is auto-logic in houston. they're highly respected in the honda world. they do awesome work. i took the car by there about a month ago. guy took a look and said yeah, we can do it.

fyi, ion's turboback replaces both the stock midpipe and downpipe.

That's assuming iON ever releases it...

I wish they would just show us pics and more info on their products. I don't get the whole thing with having to contact them about everything. It just makes things hadere to go about getting what you want.
