i know that having a bellmouth design is a good thing.. but i was wondering how much power is really being lost with an HKS downpipe... the reason is, is that i am most likely going to get an HKS uppipe, and downpipe for only 250 brand new... and if the downpipe is not that great then im not going to get it.. i am shocked to find out that i can get these for so cheap.. but i was wondering if a big difference in power is being made coming from an HKS downpipe, to a bellmouth design...

 

if your going to get a HKS downpipe, you might as well just gut your stocker, it would be the same thing....

the HKS is cheap because it sucks....(i know, not very helpful)...

go bellmouth or divorced....

put 2 straws in your mouth, blow.... = divorced

put 2 straws in your mouth, place hand over one of them, blow... = HKS downpipe

 

so basically even at that price.. its still not worth it...

 

my opinion, no....

although, I have heard nothing bad about their uppipes...

 

ok thats good about the uppipe.. even though if i was going to get the two.. i would want the same company.. i dont know why its just a fetish to have as least many different brands on a car... but yeah

 

for some extra $$$...go for crucial racing up/dp...all gasket, studs, ceramic coated, lifetime warranty...

for a little less $$$...TurboXS makes good stuff....


I have the Crucial UP w/ TurboXS TBE

 

I just bout a gutted stock uppipe off ebay and then went with a helix catted dp because of the nice bellmouth. Dont go hks, they make great products but their downpipe is not one of them.

 

If you want a cheap yet functional polished stainless steel bellmouth dp you may want to look into the ERZ catless bellmouth dp. I bought mine new off of ebay for about $130 ($180 shipped) and am happy with it thus far. Had alittle difficulty installing it (you can find my experience with it in the reviews section on this site) but it has treated me well. Hope this info helps!

 

i dont agree i think the HKS is fine

if it was that big of a deal subaru would have done the same

the flapper angles towards the hole.

when closed ie on boost the exhaust goes strait through down teh pipe

for the record: im not saying the HKS is better i just said its fine

 

pick up a used helix DP. great product.
dont get the HKS.. like they mentioned above, its just like the stock but w/o the cats.

 

yes i do agree with DLUX WRX. helix u/d pipe is great and great sound comes with it too. but sometimes it back fires out of my HKS HIPER exhaust.

 

Snort! Pop! GROWL! There is NOTHING wrong with that

if you buy the hks, ive heared of people going to a local muffler shop and making it into a twin dump like a bosal downpipe for cheap. but otherwise the hks does suck, i suggest you dont get it. my 2 cents
