I dont know what y-pipe and HFC/Test pipe to get. im liking the Tanabe y-pipe and idn what test pipes (ill only go HFC if it doesnt save me money by going test pipes). i dont know what diameter piping i can go with the y-pipe and test pipes if the amuse has a 3 inch pipe. what would you guys do? i have 5 weeks before amuse gets here so i need to order this stuff quick.

i went with the stillen Y-pipe.....very easy to install and near perfect fitment.

 

Hi,
I'm going to order my Amuse r1 too and since i won't be using any Test pipe. I will mix the R1 with Fujitsubo Y pipe + crarwford HFC + Tomei headers
hope it helps

cheers,
Jerry

 

thanks, i think im going to go with the tanabe y-pipe and an ultimate racing hfc

 

i like that fuji y-pipe, i think i might go that way. what diameter is the crawford hfc and does it let the CEL come on

 

yea, thanks a lot jdm, im going to order the fuji and crawford today, thanks for your help. i apreciate it.!

 

UR Y pipe and UR cats would compliment the Amuse very nicely

 

I just had AAM high flow cats and a meagan y-pipe installed. Im very happy with the set-up and sound so far. The car feel more willing to go fast.

I dynoed at 252 RWHP after the install, but unfortunatly I didn't get a baseline dyno to compare to. I also have a pop charger and AAM plenum spacer which contributed to that 252 RWHP.
