can you still put a y pipe on a true dual exhaust?

 

nope....y pipes are for stock setups and y pipe back setups

 

i don't know "y" you would want to do that....this design is intended for single exhausts from the cat back

 

just wondering. i din't think you could though..

 

Nice!

 

Road Warrior,
Have you installed the Y-pipe yet? Just curious if you've gained a *slight* rasp from it (assuming you have non-oem exhaust).

Many of us, inclusing myself, gained a small rasp after the Fujitsubo Y-pipe. I wonder if this new design w. the 'H' section cured this issue. The function of the 'H' section is for accoustic reasons ... if it were meant as a simple brace, it would be a lot easier and simpler to weld a tab there.

 

unfortunately i have not had the time to install my y pipe ....sucks, especially since i waited so long to get the darn thing.

however, since you bring this up i will address this issue and provide feedback once i have the y pipe installed. i am wondering if the JIC y pipe has a rasp only because their pipes are seperated more so from the collector than the fuji design. there are a few other manufacturers that have the same design as the fuji and i have heard of complaints of a rasp....specifically, the obx y pipe and i am not sure of the others such as the kumura y pipe

also, right now i do have the OEM exhaust from the cat back...i am planning to install the y pipe at the same time as the fuji ti catback when it shows up should be soon

 

If memory serves me correctly ... JIC owners also experienced the same slight rasp. We certainly look forward to your update and thanks in advance!

 

i find that to be surprising....could the rasp be coming from another area....cats, or exhaust

well i am very curious to see the results myself now...

 

It's not all that surprising actually. The source of this rasp is the muffler itself ... likely the flat outter walls. These non-oem y-pipe altered the accoustics in such a way that readily excites the muffler under particular conditions. The only way to combat it is either actively dampening the 'buzzing' part (very hard) or carefully tune out the particular excitation frequency via carefully placed and sized resonators or 'H' crossover.

This largely theoretical ... we won't know until you try I'll keep my fingers crossed!

 

nice! glad you got the fujitsubo y-pipe quickly!

took forever to get that container over here...

do you have your TI exhaust on order already????

enjoy it!

is it a 3 inch system?

 

don't know off hand, but i called the manufacturers/distributors to make sure my exhaust components were properly sized....sorry i can't give specifics but that would be my recommendation if you want to be sure
