I've got the standard end cap insert, 20.2 mm ID and the "pea shooter" insert 13.2 mm ID
That means the pea shooter insert offers only 42% of the orifice area the standard insert does.
Can someone educate me on the "GYTR" insert for the stock aluminum exhaut?
I'm talking about the "GYT-5TJ93-75-01 Quiet GYTR mufller insert as seen here:
That ID looks really huge! Are there any fancy internal workings, or is it just a straight pipe?
zooming the pic on my screen measuring it and calibrating it with my end-cap
I end up with an ID of 26.5 mm for the GYTR Quiet insert.
That would be and orifice area of 158%, compared to the standard insert!
(or 369% of the pea shooter)
