The ETS Exhaust system is a direct bolt on for the E90 and E92
This exhaust systems is constructed from dual 2.5" mandrel bent
304 stainless steel tubing with stainless steel v-band connections
and OEM mounting locations and utilizes a unique crossover/x-pipe
that helps to equalize exhaust pressure; even though this isnt
aplicable for scavenging on a turbocharged car, this extra effort
tunes for optimal sound quality.
The ETS exhaust system comes with dual 4.0" stainless steel
tips. These tips are 100% stainless steel and not chromed like many
other exhaust systems... these tips will not rust!
