Yah I was on that site and it said make sure to measure and check fitment before ordering. I'll check into it more

If you’re 6G mustang there’s plenty of room. Secondary O2s point inward

6G it is and thanks for the info! Might try these for such short change.

Sorry to dig up an old thread - but I have Kooks LTH + Green Cats with a tune. The car ran strong/great for about 600 miles then I got the P0420 code. It came and went intermittently on its own but the car still ran great. Finally, after it coming back on recently I thought I'd give the Big Daddies Garage angled 02 spacers a try.

Since I put these on, the car now occasionally stutters at idle (never dies) and now I've got P0133, P0153 and still the P0420. Thoughts anyone?

Sounds like header exh leak on bank one and/or the wideband O2 on that side is getting lazy.

Hi did you solve the issue? I'm having the same Codes

I keep getting the same codes. I have vibrant spacers and went years without codes until I switched to a resonator delete x pipe.

I have an H pipe. No further issues since the spacers
