I am in the process of wading through the numerous exhaust threads in an attempt at figuring out which one to buy,and as a tool maker I have picked up on one aspect of one of the reviews:specifically about the megan exhaust, where some remarked about how easily the tubing seemed to bend during the install.This speaks volumes about the GAUGE of the tubing used!Does anyone have any definitive info on the gauge of tubing used in all the aftermarket systems out there?Also, as a welder of stainless tubing ,I know for fact that the martinsitic properties of 304 SS changes dramatically when the heat of welding is applied:ie it can, and does corrode.Bear that in mind when looking at various systems which feature welded flanges instead of slip fit joints(milltech etc.)

 

Aggggghhhhh! Martensite! Flashback to Mat. Sci! <runs screaming to the nearest bar>

In this thread, they claim to be using 14 gauge 304 stainless:

Anyone here with experience in converting the stock MCS exhaust to a one ball also any before and after dyno charts, is this really worth time and effert?

 

an exhaust project (or four) in the works:


alloy is Ti CP-2
