straight pipe exhaust

Who else is running straight pipe exhaust? Kooks long tubes with full 3 inch exhaust no cats or muffler.:stickshift:

 

Aside from being illegal, it seems like you'd probably want to reprogram your ECM because your exhaust sensor data is gonna be odd and maybe throw your ECM into open loop or maybe the ECM will just get mix/timing wrong.

 

It will be so loud that you will back off the throttle faster, saving gas.. you are a hypermiler!

 

Welcome to the forum?

 

A full 3-centimeter exhaust works for me, and has taken me a lot farther than you'll ever go with that 3-inch.

 

Could be a heavy fine w/o the cats in place.
