So these two have absolutely nothing in common except the fact they're both on my Dakota. I was wondering if anyone has tried a Cherrybomb Glass pack or a blue bottle on a 4.7. If so, how did it sound. And I was wondering how I could find out my rear end gearing without looking at it. Like, anywhere in the book or on the truck that would tell me....or maybe the VIN? Thanks for the help

 

There should be an option sheet on the inside of the glovebox lid. Otherwise, crawl underneath and look for a tag on the rear diff, usually bolted down on the cover. My 4x4 also has a sticker wrapped around the passenger side stub shaft sticking out the front diff.

 

my dad has glasspacks on his 4.7 and no converter and it is raspy as hell...i would go with flowmaster 40

 

My rear end is....3:55 I do believe... I asked the dealer here and they checked my VIN for me...uhh I think I am going to go with a Glasspack and keep my coverter on...cheapest route for me

 

go with the flowmaster 40 series. you will thank yourself for it.

 

Hey Cris,, Is the FM 40 one in and one out? Want to save costs. Also, What is a MX10.

 

Ive got the flowmaster 40 series. Best sounding exaust ive ever heard. Ive had glass packs and this doesnt even compare.

 

you can get the FM 40 in 1 in 1 out or 1 in 2 out both sound great on the Dakota
