That's what SHE said.

Lol. Ok then, is this better?

Always nice to have a box waiting for you when you get home.

what if the box has already been opened?

It's all the easier to open the next time 

Older Xforce cats are notorious for semi collapsing so I wouldn’t be surprised if it’s a combo of that and soft springs, the twin 2.5* is fine unless a muffler is on the collapse also, which isn’t unheard of on Xforce either 

^Is there any advantage to getting a 4" exhaust over a twin 2.5 if you're not gonna push it to the max?
Like say you're going for 400rwkw will you get it a little easier with the 4" or no difference until you're getting to the upper limit of the twin 2.5?
I hate drone but also wouldn't wanna waste powers

Down low bigger exhausts actually have counterproductive power generation properties and the full effect of a 4* system is only seen above the 1000 HP mark over say a 3.5*
