Tanabe Y-Pipe
 

Has anyone installed this Y-pipe by itself on the stock system? Its been done and reviewed with HFC's or as the entire cat-back, but what of just the Y-pipe. Has anyone done it yet? Any sound differences, volume, etc.?

look up member "christian370z" for he has thy setup thou is looking for.

He has HFC's though. Im waiting for him to post a vid of his setup for me.

I'm one of the ones that installed it after HFC's. I dynoed stock, then with HFC's and then swapped in the Tanabe Y-pipe. So I guess I haven't done what you were asking but can tell you that it will deepen the note of the exhaust a bit, reduce some rasp and give 5 hp throughout the curve. I would say that if you are not going to go with HFC's down the road then the Tanabe Y-pipe would not be worth it as the best part of the y-pipe was that it reduced the rasp from the HFC's
Hope that helps

Thanks, did you have any trouble with the converter bolts?

Yeah, I'm sorry I can't give you more info at the moment 6spd. I will be taking video this coming week both inside the car as well as outside so I will let you know when I get those posted.

cool, ill be anxiously awaiting it! i am very open to the idea of doing HFC's and the y-pipe. No way will I replace the muffler though, that'll get too loud.

1 of the Cat bolts was on rediculously tight. Had to use a huge extension and breaker bar (with a jack handle on it :) )

The combination of the y-pipe and HFC's sounds amazing. Zero drone but aggressive when WOT. I achieve most of the gains of a CB but still looks stock and is not as loud

i hate having to do that. ive broken like 3 breaker bars in just the past few years...

I think Christian made more power with this setup than others with just a CB. Im not sure though but i think so.

I have only compared myself to other 370zs that have dyno'ed on the SpecialtyZ dyno just to keep the dyno issue out of the equation: my car put down similar if not more power than intake/CBE/tune 370s that had gone before. I am happy and was pleasantly surprised at results!
