I got a ets extreme exhaust and a cat less downpipe coming. What should I be worried about these new mods?

A check engine light if your not tuned and thowing fireballs if you are. Also, lots of cabin drone and the possibility of waking the dead on WOT.

A crackle tune with that setup would make your local Law Enforcement very very happy.

If your not tuned you'll need a J style O2 sensor spacer to avoid throwing a code.

Please introduce yourself on the Introduction thread (under site news). Welcome and enjoy!

I got a Scorpion catless downpipe and ETS Extreme (no mufflers). Cold starts sound horrible. Neighbors about a mile down the road can hear me.
Flames are cool though.

Same setup as Hank but with the res/mufflers. It's loud, and even with the res/muffler version there's a lot of drone.

I've had so many compliments by other drivers on the sound of the car, and the fireballs haha

You guys are not in SoCal....

Good for you as the 5-0 will not stop till you get a ticket.... or towed.

Geez, and I thought the AWE track edition (no mufflers) with stock cat was bad enough
