dunno but the stock cat was definitely restrictive as heck on the 2.5. my car runs a lot better w/out it now.
For Sale: MKV 2.5 automatic transmission
5 cylinder FTW
Testpipe: 2 ME: .75
For those that are semi-mechanically inclined, but have never done anything with exhaust/headers/etc.. The concept of the install is EASY.
Until you try to remove your o2 sensor... Fail #1
No form of wrench or dousing of PB blaster worked on this SOB
Ordered a specific o2 wrench of amazon. Continued Fail.
Solution? remove the plastic cover where the o2 sensor wire connects, disconnect wire, remove pipe. Step on pipe, remove o2 sensor, scream out loudly like a victorious barbarian.
Put in your fancy new pipe, bolt it all up nicely, only to realize one of the 4 rusted, corroded, grimy looking bolts that connect your testpipe to the exhaust header is stripped FAIL #2.
Solution? Hook it up with 3 bolts, swear loudly that it's after 6pm on a sunday and there no where to go to get a bolt.
Then proceed to drive it around, as it sounds SEXY, and gave a nice little kick in the seat along with the lightweight flywheel you installed earlier.
Which leads me to my next question.. Does anyone know the part number for this? Can i match up the thread at a hardware store and screw in a normal headed bolt as opposed to that strange 2 sided threaded contraption they have on there stock?
'08 Rabbit- P-Flo, Torque Insert, C2 SRI+Tune, USP DP w/HF Cat, Lightweight Flywheel, BFI Engine&Trans Stage 1 Mounts
just get some stainless bolts and some loctite. thread through the flange and BOLT that bad boy together.
i had to clock mine just right to get the turbo downpipe to bolt up. but using bolts and nuts is a MUCH easier approach over using the oem studs. they get brittle as they go through heat cycles and inevitably you'll end up either stripping one or breaking one (i broke one)
overall i REALLY like what usp has made...
great build quality, a nice flex section. and NO CEL!
now my only gripe is with the flex section. it is only a case with anyone that has a turbo. but that flex pipe doesn't flex much. and in turn take A LOT of thinking/loosening the downpipe and exhaust just to get it to line up (barely) but once it does all is well...
I might suggest they make that flex section Just a little bit longer. only to accomodate those of us that have turbo's it's not a big deal, but it could help since i think more and more turbo's are going to be on the road soon
god i love my car. it may not be fast, but it's crazy fun!
C2 stage 2 TURBO!!! ACHTUNG!!! 2.5liter 5cylinder contents under pressure!!!
I put mine in last week with the high flow cat, and a bosch 02 spacer. my cel came on and vag com reads 02 deficiency. should I try the 42DD 02 spacer and see If that works or.. Is it not gonna make that much of a difference?
Yay, though I walk through the valley of the shadow of Honda...I shall fear no turbo........for thou art with me....Thy torque and horsepower shall comfort me.
i have a 42 draft designs and it works as a charm
