If you are running an HKS downpipe, let us now how you like or dislike it.

I'm getting one put on this weekend, heard amazing gains, but heard bad corrosion reviews from winters.

I have seen some pictures of very badly rusted hks downpipes so I'm sure it is possible

I love my HKS down-pipe. It is the most bang for the buck. If you are worried about corrosion have it coated. Most down pipes will corrode; my Borla one was the worst.

its already titanium particle coated, however if that coating gets scraped off then you have a problem.

i have a hks dp i have no trouble with it i havent had any sign of corrosion on it that i have seen. and for the money you cant beat it

it is great and it only costs a little to send it off to jethot and get their 2000 f coating, plus you get to pick a color. the only downside of the dp is it has a plate on the wastegate so you get wastegate flutter like the stock dp. if mine ever corrodes i will get a bellmouth unit

Unless HKS changed something fairly early, I've had the HKS on for two winters now. Real, salty-road, sand everywhere, 8" snow-in-1-night winters and I have absolutely no rusting, pitting or even chipping in the ceramic coating. :banana:
The pipe is indeed SS, not mild as some have said. It is the SS alloy that has some magnetic characteristics (the tubing but not the flange) so you can't check it w/ a magnet but it is SS.
While I fretted over the fact that it is the flat-plate design instead of the bell or semi-divorced, I can hardly be happier with it.

how many of you have added a "twin dump" style tube for the wastegate gasses?
