It’s great for emissions and MPG but I’m thinking this is going to limit anything the Aftermarket Exhaust companies can do for the V6’ers “BIG TIME”. And right now it's good to be a V6'er when it comes to moding. With this new head design , I would like to see total HP gain with a full aftermarket exhaust set up. Right now most full set-ups with long tubes are getting people 30+ HP.
