Thread: Positioning of Glasspack

Hey guys. I have the SLP Power Flo cat-back exhaust with Speed Daddy headers, which I'm looking at adding a glasspack to (to reduce cabin drone). I got under the car, and it looks like I'm going to have to put the glasspack after the middle hangar section (where I circled in the picture below):



Will putting the glasspack this far back affect how much cabin drone it will reduce?

Thank you!

Thats where the stock res was.

I'd say horizontally... just kidding. I also just put one in my GTP and noticed that the resonator was only 2 1/4" and I thought it was 2 1/2" so we installed a 2 1/4" glass pack, is that right? any thoughts?

Stock piping is 2 1/4". The cat-back I have is 2 1/2" diameter.

I thought our exhaust is 2.5 until the Y, then 2.25 after. Am I wrong?

yes.
