Brobst05GT

Hey guys, I have a 2005 Mustang GT. I had purchased the off road H-pipe kit with high flow cats, but because of an issue in not getting the high flow cats coupling up to the downpipes (apparently pypes doesn't include anything for that) I've been running without cats since then. I'd really like to be able to clear the check engine light and I know they have o2 sensor delete kits you can buy, but i've heard that they're hit or miss in their effectiveness. Any reccomendations?

do you have a tune? if so just get an updated tune to turn off the codes from the cats not being there. most places that sell tunes have free tune updates.

When I had my O/R H-pipe, I bought the MIL Eliminators from Brenspeed. I never got a check engine light with them. Maybe give them a call and see what they say.

No tuner yet. but that's a good tip!

I got my MIL eliminators from Brenspeed, they work, but I just ordered a tuner after 2 years of not having a custom tune.

A cheaper way is O2 non foulers, buy 2 pairs from Autozone, PN42009, and drill out 1 in each pair with a 1/2in bit, then hook it all up. Costs $10 total.

I emailed BBK about this and they said mil's aren't available for the s197. A custom tune is what most guys are using to turn the rear O2's off. But beware, many some states during the emissions test will pick this up and fail you for having the rear O2's turned off.

So, I'm assuming you're referring to the spark plug non fouler? I'm not 100% clear on how you were saying to put this on. Could i get you to elaborate? Not sure what exactly i'm drilling, or how to hook this all up
