Just got my fabspeed pipes remove and put my stock cats back on. i did the cat by pass pipes last year and it was great but then wanted a little bit louder so i did a Tubi exhaust few months back. OMG it was loud. My last post i shared was about how i didn't mind too much of loudest but more of how it sounded..i was not happy how it sound like a dodge ram and sounda very loose at low rpms. well i decided to finally trying keep the exhaust and put the factory cats back on. Now the truck is more quiet and still have a nice sound on the outside but i am very please with how it sound now don't have that nasty low rpm bubbles and loose sound. stange thing is that a turbo car should be soo much better in performance with less back pressure..but with both exhaust and cat bypipes i felt i lost low end(pick up) response like there is no back pressure. now it's picks up and take off more smooth.
so i do have set of fabspeed pipes and turbo rear valance. PM me if anyone is interested.

 

Not enough posts for PM. I'm interested.
