strange one...

[rexe]

Just looking for an exhaust system for the ph1 172 and in the past i have used ashley exhausts.

had a look around and they only offer a 2" bore size, which got me thinking as i thought the std exhaust system is slightly larger at 2.25 or is is 2.50"

I was all up for buying an exhaust until i read that.

I was just wondering if im correct in thinking the standard ren exhaust bore size is larger than 2"

says somewhere on yozzasport that they tested the different sizing and found it made no difference. im sure someone will come along with a link
