I need HELP!!
I don't understand why any vendor, (besides AAM) Sell a cat back exhaust system for my 2009-Nissan-Maxima, that doesn't flange up at the y pipe. Does anyone know if there is a product out there that I've missed. (I.e. megan, stillen, borla etc.) That sell a cat back exhaust system that does NOT marry to the 22" muffler/resinator outlet, and goes straight to the y pipe?? Does any company carry a CB system where I don't have to buy a test pipe to connect the CB to the ypipe ??

 

damn, good qstn...

 

That question makes no sense.
The third cat is part of the y-pipe.
Do you mean the mid-pipe, that contains the resonator,

Cat back vs axle back exhaust.

 

The AAM exhaust also connects the the stock Y-pipe like all the others do.
The Racingline Y-pipe has the third CAT delete.

 

AAM, Borla, Stillen, Megan, Motordyne (coming soon). They exist, these are just the ones Ive heard of here on the .org.
You can also build one of your own: Magnaflow mufflers, Flowmaster mufflers, Magnaflow resonator, glass pack as resonator, etc etc. Research (Google is your friend...).
