But not high flow. They allow a little better flow than the original converters, but not much more. They do sound better though. If I can get true duals on my car, they may work even better and the y pipe may be the main issue I'm having. Installation was a cake walk. Getting the old ones off was a pain, but these went on very easily. Would have been better if they matched up to the OE air injection without modification, but that's not a big deal.

Magnaflow mufflers in my opinion are the best choice in every category. Nice looking, superb quality, long lasting, and the perfect deep tone. No hollow beer can resonance like some of the competitors. I have used the large body Magnaflow muffler on numerous SUV's & truck's and have never been disappointed. The large body (12588) also eliminates the drone effect in newer vehicles with AFM cylinder drop. Great muffler...highly recommend!
