Mine is plenty rumbley when I am cruising around. It does smooth out a bit in the higher rpms but I actually like that.

Same as above for me best rumble party is under 4k revs

If you can tune out CELs with OFT on these cars and not hinder the ECU readiness checks, i'm going to be thrilled.

This is the answer I got from the OFT guys.


"The P0420 is turned off when you run our stage2 map and no CEL will be present.

We are disabling the O2 monitor.

If you "catted" header is emissions friendly then you can simply run a stock tune when you need to pass your state emissions test. "



I assume if they disable the O2 monitor you will not pass inspection as the monitor will not be in a "ready" state.


I have a "hypothetical" acquaintance who shall remain nameless .
He/she runs a catless header with an OFT stage 2 tune and supposedly gets the car passed emissions.
I will be seeing said "imaginary person" in a few weeks and pry out the secret from him/her

I just passed a few weeks ago running the Stage 2 UEL tune. Didn't do anything special. Although my mechanic did have some trouble getting the machine to read my car the first few attempts...

Just curious, does NY require all monitors to be in a ready state? In NH, if any monitor shows "incomplete" (not ready) you will fail emissions. When you reset the code all the affected monitors go to their incomplete state until the required drive cycle requirements are met. Once met the monitors are ready and you carefully drive your car to the nearest inspection site and cross your fingers .
I'll being talking to my "imaginary" friend to see what they do to get through inspection. Hopefully I'm wrong and the easy fix is to go with OFT. I'll post back later with what I find.

CEL disapeared as fast as it showed up for me, within 24 hours it was gone. I have a an aftermarket catback and K&N Drop-In air filter. It's UEL is 6 inches difference, not the most UEL there is, but I like it.

Thanks guys. I'm interested to see what it might sound like with my muffler delete now. Should sound nice.

I had this exact setup. Recently changed it out though so unfortunately I can't provide a sound clip. They compliment each other perfectly. It is a little louder with a little more rumble to it. Still no highway drone, but it is a little more louder on the freeway. There is a very slight rasp at wide open throttle in the upper RPMs, but sometimes that isn't even noticeable.
