Those with C32 and SL55 Y-Pipe....

The 'STOCK' inlet tubes are still on the STOCK splitter. So, I don't think you used the STOCK tubes. They are also shaped differently, with less 'ribs'. Also, notice the factory clamps holding the tubes onto the SL55 Splitter...those are non-adjustable (making me think the SL55 Splitter came with these tubes on it).
Am I missing something? I'm not trying to argue, just trying to figure this out...right now, I feel like this :
lol
Still looks to me like you used the SL55 intake tubes with the SL55 Y-Pipe, and the stock tubes are still on the stock splitter.
Thanks,

Just curious as I have the parts coming in this week. I got them to add the P/N to the search feature on oempartsdirect. Their database shows just the individual parts that you can't order. If you do a search using the new assembly number it come up though.
Does anyone have a pic of the extender pieces they made from the couplers to adapt the SL55 hoses? Is the joint between the extensions and the hoses hidden under the outer clamps?
Thanks,
Chuck

BUT, I think the length is correct.
I'm afraid c32used is mistaken..???

now for posting something without double checking so yes it appears I got the splitter with its tubes connected but still used a rubber spacer pictured at beginning of thread cut in half and streched it some to get a very snug fit. Thanks for letting me know my errorNot offended what so ever just feel stupid for not checking and going by memory.

I used a 2" x 2" Flexible Coupler by Americanvalve.com , sold at Lowe's for around $5/ea.
If I understand this post now, the SL55 air tubes are larger than the opening on the stock air boxes. So, you basically cut a thin piece of the 2" coupler to act as a piece of material to fill the difference between the outside diameter of the stock airbox, and the inside diameter of the SL55 air tubes.
C32used, No prob man...I knew I'd talk you out of your funk eventually
Dyno on my car is scheduled for Saturday, 10am cst. We'll see what happens.

274.45hp / 284.13tq
Run # 2 - WITH SL55 Y-Pipe (005.drf)
273.47hp / 282.60tq
Run # 3 - W/OUT SL55 Y-Pipe, stock (007.drf)
283.29hp / 289.30tq
Run # 4 - W/OUT SL55 Y-Pipe, stock (008.drf)
280.77hp / 283.83tq
-All runs were on a Dynojet dyno, 80* air temp / 95% humidity.
-All runs were done in 4th gear
-Fuse #17 & #18 were removed for dynoing
-Car would hit a 'rev-limiter' at 5600 rpm. The guy said there is probably another 10hp if it would hit redline or closer.
-The graph looks 'odd' because you couldn't MASH the throttle without it kicking down to 3rd gear.
I'm anxious to see if anyone dynos their car with the SL55 Y-Pipe AND the SL55 inlet tubes, or even the whole SL55 airbox setup (complete system).
So, in conclusion, with K&N Filters - the SL55 Y-Pipe HURT the car. Remember, I do not have the SL55 Inlet tubes...I made the stock inlet tubes fit (which could defeat the purpose of the SL55 Y-Pipe).

Hey there ShawnQ:
THANKS for the good old fashion work
God how I love this site!!!! One less mod for me to have to worry about. You know after all is said and done, Those boys over in Germany REALLY NO THEIR SH_T.
See yeah
Without being able to open the throttle up through the whole dyno run because it would down shift...we could be missing a low-end gain over the stock pipe. Although the peak power is less, the low end may be what makes it 'feel' faster out of the hole and around town.
Otherwise, I could've been mistaken about the 'noticeable' gain due to the fact that you can hear the supercharger much more and you can hear the intake better.

Others have done this same experiment with similar results - that's what I meant by "conclusively", I wasn't just going by people's guesses
Maybe with some supporting mods/programming it would be different/more intuitive.Nice process though.
i added a pic of what i found.. sorry i dont the pic from my car but i just used on of the pic u guys posted.
well in the pic the red circle on the right shows a mettle clip, there is also a mettle clip that u cant see in the red circle on the left.. which is behind the SL55 splitter hose, as u drive that hose moves back and forth and the mettle clips starts cutting in to the hose. which over time can create a small hold in the hose... to fix this problem what i did was just re-located that clip a little to the left. the only mettle clip that rubs is on the right side of the engine. Something u guys should look at.. a leak in the hose could cause problems

I just couldn't believe that I LOST 10hp with it? Didn't make much sense!
