When I switched to the true dual setup thats on the truck now I did loose some of the low end grunt but made up for it from 3500rpm up.

(you can actually go to their website and hear it, before you buy it.) I don't know what style your truck is but, Advance Auto has the best prices on the Dynomax exhaust kits and it only takes them about 3 days to get it in. I myself am fond of the dynomax exhaust for the 4.7. Does anyone know if it'll be louder the closer the muffler is to the cat? Did you notice any loss in low end torque or back pressure? I am probably going to just stick with a single in dual out muffler. I think they sound too raspy and not nearly loud enough. As far as Magnaflow goes I know there are a lot of Magnaflow fans on this site but, all they are really is a fancy oval shaped glasspack. Its a lot louder now but doesn't sound as good. The only reason I removed it in the first place is because I installed a true dual setup that came with mufflers as part of the kit. All I can say is wow, did it sound good! I'm about to put dual Flowmasters back on it to get it sounding as good as it used too. I had the exact setup you are talking about on my 02 4.7, Flowmaster 40 series, 3in from the cat to the muffler and then 2.5in out the back. I want a deep throaty V8 sound with no snap crackle pop. I know Dodges are louder than Chevys to begin with, but I want something a little louder that does not have any raspyness or pop to it like I would assume a glasspack would. I had a FM 40 on my last truck and as I got used to it,it was really quiet.

Also, I'm trying to decide betweena Flowmaster origional 40 or the 14' Magnaflow. Do I do a 3' in and dual 2.5' out, or what? I don't even know what the stock size pipe size is. My first question is what size pipe to use.

I know, but I'm 19 so that explains it all right there! Anyway, I want a single in dual out muffler with 4' tips that are 45 degrees behind the rear axle. The only thing I want is a louder exhaust. I'm about to buy my dad's '03 Dakota 4.7 from him. Hey guys! I know this has probably been gone over a million times but I did not find the exact answer I was looking for when I did a search.
