Beer Can test - which 3" exhausts are really 3" ??

Guys - after a recent debate about exhausts I have taken it upon myself to compile a list of which exhausts are near or close to a real 3" through the muffler

I have found that many exhuasts that my customers think are 3" are actually LESS that 2.5 " inside the muffler

I devised a simple gauge to test - a beer can

Those mufflers that can fit a beer can inside the tip to the core of the muffler pass - those than can not fail


Excelent - loads of room - OVER 3" inside muffler

Buschur Racing
AMS
Greddy Ti
RNR copy of Buchur Exhaust with BR racing muffler




PASS - between 2.5 " to 3"

SS Auto Chrome / a/ k / a SX Power
Megan
Apexi
Magnaflow 3" system


Bearly PASS - just sneaks the 2.5 " beer can in

Stock 2005 MR
APS
RNR "stealth with magna flow two resonators and black spray paint that scracthes"


FAIL - LESS than 2.5" passage insde muffler - less than stock

HKS
AVO
