after cats X pipe

[vrpirata]

Magnaflow is selling the 15447 X-pipe: "Weld in place behind OEM converters & O2 sensors", somebody has it already?.

I was wondering the same thing. Anyone actually have this, or pics of it installed?

Ive seen it installed, you get about half the gains of the full catted X pipe...so about 6-7rwhp

I just got mine won't go in until it gets a bit warmer around here. With emissions around here I need to keep all the cats. But, I have only seen the full catted x-pipe gain 4hp but lost 2ftlbs of torque compared to the weldbehind.
I got a deal on the weld behind because it included the first cats and O2bungs and I won't have to hack up my factory exhaust.
