It isn't the no backpressure part, It lterally collapsed or clogged creating roo much back pressure. Our trucks benefit from having the rear cats removed completely.
I told the guy that i would like to put in some high flow cats, and he wasnt having it, said no way federal law yada yada. Texas doesnt even have emissions testing. but for $300 its a cheap fix. Just wish i lived close to shops that know our trucks!
