awesome difference for way cheap. sounds good!

 

thanks md, I think for the price, it is an awesome mod......

 

So what would the price difference be roughly between running a 3" into a bullet vs stock 2.5 with bullet, bout single pipe and dumped.

 

The sound will only get better. I have about 5k on my bullett and it sounds great.

 

Hello. Can you post some photos of your Dynomax #289-24215? It seems it is fits to your truck.

 

^ I can post pics of mine. I installed it two days ago. And it sounds pretty good. Not very loud but its a S/O exhaust to tie me over until I can swing the 800 for a full dual stainless MBRP exhaust

And for the people that want steps on how to do it theirselfs because shop install is a waste of money IMO if you have the means and skills to do it yourself

Take a sawzall and cut the stock muffler off at the flanges on that (so it can be re used if need be)

I needed 20 Inches of extra pipe on my FX4 SCREW 5.5 foot bed. That way you have the pipe going over the other pipe a few inches

Measure where you need the extra length of pipe and placement and take a sharpie and mark where on your extra pipe, then cut the extra pipe off with the sawzall (cut straight to use the cut piece for the tailpipe extension). Remove it from the truck and put it in your vise, then make a nice weld bead all the way around the flange of the bullet to the new pipe.

Then take your newly welded extended bullet and slide back under the truck and slide it onto the Y pipe. There will be a few inches left from the back of the bullet back to the tail pipe, so use your extra pipe left over from the pipe you bought (again I need 22 inches extra) And take the shorter piece of pipe and measure that and cut to size. Now slide it all together so it fits well. If you cant hold it all in place by yourself to tack weld it in place then grab a buddy to hold it together while you hit each connection with a tack weld to hold in place.

Then run a nice bead all the way around each connection, Let cool and hit with a coat of VHT (what I did anyway to help prevent corrosion) Run for 5 minutes with the VHT to help bake on then hit with one more coat. Then enjoy your new exhaust!

 

Sorry for the delay there "Makind", I was on vacation plus my NAV messed up on the way back home. Here ya go.....

Very nice... you have now inspired me to do the same with my truck. I'm not looking to do the entire system, but it looks like replacing the muffler to a Dynomax bullet is just the thing I need.

 

How is the when you're cruising and going at highway speeds?

 

No cabin drone, you can hear it when you are stepping on the gas pedal. (especially with the windows open but here in Texas, we leave them windows up) Over the weekend I went to Austin and had the truck on cruise control; I forgot I had the bullet because I could not hear it. I just heard wind noise...

 

Got my Dynomax bullet installed yesterday and I love it. I was shocked at what a difference it made.

 

Sounds good I'am looking to change the sound with a little rumble. Where did you buy Dynomax muffler from?

 

Here is where I bought it from. Trust me, you won't be disappointed.

 

Glad you are liking this mod there Narv.....

 

My bad... forgot the link.
