Magnaflow Y-pipe has a smaller cat than stock
 

Hi all,

Getting the chain tensioner job and had to also buy a Y-pipe. The only one I could get reasonably priced and quickly shipped was Magnaflow, and it looks fine in all respects, except that the cat size is about 30% smaller than stock.

Is this Okay for VQ35DE?

is it the same where it bolts up to the other cats?

The pipe diameter and all bolt-on flanges are exactly the same. Only the diameter of cat in the Y-pipe rear where it bolts to the resonator is different.

that cat don't mean anything its purpose in life is to catch anything the 2 main cats may have missed as long as it bolts up the same ya should be good

I hope Magnaflow knows what they are doing

I trust them
