Finally, a solution for headers and cats on an
E46 Non M!
Less radical than race pipes, and wow, what a value!
Headers and high flow cats are one of the mods that
E36 & E46 M3 enthusiast have been enjoying for years;
but sadly, these mods have never been easy to find for the fun to
drive E46 non-M models.
Now we have something for you! This package contains a complete
center system in 304 stainless steel, with C.N.C. cut flanges and
metallic-core high flow cats; all in one box!
We were excited when we found this and the value is excellent...
Compatible with your factory, or a replacement performance muffler
and T.I.G. welded for durability. Oxygen sensor bungs are in place
in the header and after cats for a flexible installation.
These kits add Horsepower and Torque so you can expect strong
gains in low RPM power as well as a improvement in high RPMs.
Dyno results show 13WHP and 19Ft/Lbs at the wheels without any
additional tuning. You can even expect more with an ECU
