Steve is my DC downpipe the ver2 one? I have to ask because it still isnt here.

 

how do you guys get your perrin to fit like a champ... mine touches the transfer case slightly at certain rpm near idle... it's terribly annoying because i was told it'd fit like a champ.

 

Triny: Try bending one of the two hanger brackets that are located on opposite sides of the DP. If you fold/bend the one on the opposite side away from the TC it'll draw the DP away from the TC. Also use one soft squishy factory rubber hanger on the same side of the DP as the TC and on the opposite side use a Urethane Kartboy hanger. This´ll pull the DP off centerline a bit and away from the TC.

 

yes it is

 

i would agree,

the dc sports does fit fantastic if you want a one piece test pipe/downpipe.

we've never had a problem with them on the ix's, aside of adding 2 washers on the braces.

You guys that have experience with this: Is it just my imagination, or is the O2 sensor bung placement on the version 2 DC Sport DP a bit too far to the rear. I was thinking of relocating the bung more forward. Or is it O.K. where it is?

 

My noobishness is probably showing, but I need to ask. What is the advantage of changing the downpipe on an Evo IX? I've heard that the "Evo" downpipe needs to neck down in diameter before it reaches the cat. I assumed this applied to both the Evo VIII and IX. However, I own a IX, and during the last oil change while I was under the car, I decided to have a look at that pipe. It didn't look like it necked down at all. In fact, there was plenty of space all around it and I couldn't see any reason for it to need necking down. It was also very directly routed. It came straight down from the turbo, then gently curved 90 degrees to head toward the cat. So, what gives? Is it really worth the trouble to replace the DP on a IX? Maybe I missed something while looking down there? Could other IX owners comment?

 

The neck down is from going from a bigger pipe, like a 3 inch, to the cat which is like 2.5 inches or so. The stock pipe won't neck down because it is already small. I know when I installed my tanabe 2.75 DP, I definately noticed less turbo lag. I can't really tell a difference if I made more power or not. That little increase in HP is hard to tell without a dyno.

 

HKS GT Extension kit, combo of DP & o2 housing! Fits great and top notch quality.

 

I went with the Perrin DP and didn't have any installation problems. Fitment is perfect and performance as well.

 

The new Megan is great. Full 3" mandrel, clears oil pan, ACD, tie bars.

It should fit, its only 2.5" like stock

 

I put on the Garage HRS DP yesterday on my IX MR....it needed spacing of the lower bars, but fitment is pretty good...I might have to use heatwrap on it

 

how about the perrin 3 inch DP?

 

I installed my works 3' downpipe a few days ago along with their test pipe. The combo was expensive but the fitment was perfect. Cleared the tie bars like a champ and I noticed increased spool up and definite performance gains, I love it.
