What cats are you looking at? I priced 94106s and they were $130 before the discount. $100 after.

 

The 94319 3" /w AIR, but to be honest, I could be wrong on what size my cat pipes are, gotta check again Saturday morning. But my inlet for my magnaflow SIDO muffler was a 3" pipe.

 

What exactly are you planning on doing? Standard muffler and cats stuff or something more involved like long tube headers and a supercharger? If standard stuff that's way too much cat. Stock cats are 2.5" inlet/outlet.

 

The stock exhaust has already been taken out. Right now I've got a Magnaflow 16520 SIDO in there. It's running a 5x8x18" muffler with 2.5" tail pipes coming straight out the back. I'm hoping/planning on running a whipple with the possibility for longtubes later on, but not for at least another year. Just looking to make my cat-back a little louder for the time-being.

 

Looks like I missed something when I was searching old threads before. I should be able to use the 94106's on my '08 just fine, so those are what I'll be ordering. I'll probably just have to ask the guys at the muffler shop put in the holes behind the cats for the rear O2 sensors to avoid a CEL.

And 2 94106's from performance peddler with the clubgp discount came out to $99.92

 

100 bucks for 2 of them...go for it

 

Did. Ordered them about 30 minutes ago.
