DO NOT, I say DO NOT just go for a muffler delete.  You will be mega disappointed.
While it will sound good on the outside..   The drone on the inside will completely do your head in..
Something like this is a big NO, NO

I have a custom set up similar but with dual resonators. And the drone on light to mid throttle was quite bad.
I have had to put SS Steel Wool to plug up one side. And the improvement is outstanding.
It keeps the same sound on the outside, which is very good. But I now get no drone whatsoever on the inside.

I've done a second resonator and cat delete and it's a much nicer note than stock. It maintains the sock muffler too so no drone.

You can either have an exhaust shop do it for you or Cherry Tuning sell the piece for under $200

@Doyourbiz Are you sure you’ve had a Catalytic delete :undecided: you would have the engine warning light “ oxygen sensor bank 2 “ issues if you had done so  :confused: and a illegal vehicle :whistler:

Yes, both the second cat and resonator have been deleted with a straight section of pipe taking their place. As for error codes from sensors I wouldn't expect any since all the sensors are before that section. It's been running for over 10,000km without an issue.

There should be two oxygen sensors, one pre sensor in the header and a post sensor after the second catalytic.

If there has been no errors then have they been disabled through the ECU :undecided:

No errors because there isn't a second sensor. I'd not have done the delete if there was a chance I'd be throwing codes until I had the tune done.

After the resonator it's just pipe right up to the muffler.

the 36 second mark on this video is what the N Line/SR sound like with the resonator delete done and with the stock muffler in place.

That's an easier design compared to the GD models using two sensors :goodjob:
