 Subject: New Y Pipe and Free Flow Cat On '03 4.7?
IP: Logged
Message:
I currently have a single 3" dual 2.5" Flowmaster Origional 40 going to dual 4" tips on my '03 Dakota. I love the tone. It makes me drool everytime I start it up. It is pretty loud. I've gotten a few complaints! The only problem is I'm getting to used to it and want it a little louder. I've been thinking about getting a aftermarket Magnaflow Y Pipe and a Magnaflow Car Sound free flow cat. Will this make it a little louder, but keep the same tone? I also lost a little low end torque with the exhaust, but not much. Will I gain that slight amount back?
If you have any other opinions to get it a little louder with the same great tone, please feel free to share them. I'm all ears.

Yeah. Run the pipes into the passenger compartment and point them at your head. That should be loud for you without being inconsiderate and bothering other people.

DeereFarmer - It was increasing the flow of your exhaust while decreasing the scaveging velocity that cost you the low end torque. 2.25" pipes would have been a better choice, and could help replace that torque. At this point, you're going in the wrong direction to try to get the scavaging velocity back up - so no, what you are thinking is not the way to get that torque back.
Lead, follow, or get out of the way

Thanks Kowalski. The loss of torque is very, very minor. I can hardly notice other than going up a long hill inbetween gears. I honestly can't remember how it felt stock, so there might not be any torque loss. I put the muffler on three days after I bought the truck. I think I'll just leave it alone for now. When I replace the muffler at some point, I'll drop the pipes down to 2.25". Thanks for the input.
