Re: DT Long Tubes modification!!!
If you get a check engine light it will be from removing the front set, not the second set. The second set of cats don't have any sensors so there's no way for the truck to know if they're there or not. I removed my second set of cat 7,000 miles ago and have never had any problems from it.
