Just need a quick answer, how big is the rsr exhaust? I know the website say 60, but is that like 2.25 ?

 

60mm = 2.36"

 

exactly, and that is the interior diameter (ID).

Most RSR's I know are 60mm or 2.36". Many companies use mm's instead of inches. Unfortunately, that only measures out to 2.36 inches, kinda like my Apexi World Sport.

i think exhausts are measured in OD.

Maybe they are... but as for the Exmag's 2.36...

Just took mine off 3 nights ago and my buddy was measuring it and said it was 2.5 ID, then i was like no thats the OD... its 2.36 ID. I will remeasure when i get home but im 99.63452% sure its 2.36 ID. Ill let you know in about 280 minutes(when i get home from work )

I thought so too.

 

Ok, I was completely wrong , it is OD. After a full and careful inspection there are 4 sizes associated with the exhaust:

Piping Thickness/Gauge: ~0.06" (1/16)
Piping ID: 2.25" (2+1/4)
Piping OD: 2.36" (2+3/8)
Mating flanges: 2.50" (2+1/2)

My buddy really threw me off I guess, shoulda kept my mouth shut haha... oh well. The record has clearly been set straight regarding the RSR Ex-Mag exhaust (and most likely most other systems).

BTW... this has to be the most awesome exhaust build-wise. It has slight bends just before the resonator and muffler to tuck them up a lil closer to the undercarriage. And also has welded on skidplates/strengtheners (so if you did scrape it would be a smooth incline up to the resonator or muffler instead of a lip to bang/scrape on. Having the ceramic coating is cool too, traps a lil more heat in and cleans up easily to look brand new(even though that doesnt matter).

OK OK... late.
