Hey guy I'm looking to up grading my exhaust and i'm looking at the 4in mbrp and silverline. i was wondering wich is better as in sound as in loud or not and better bang for my buck! I'm currently run a cat with no muffler on stock 3in. Looking for some good advice!

 

I don't have any expeirence with the silverline kits but someone here will chim in... But both my cummins are running 4" mbrp systems and I really like them. On my 07 I'm running a cat back cool dual system with the cat and muffler delete and it sounds great.

 

your truck should have stock 4" exhaust.... 03-early 04s had 3.5" but then 04.5- on had 4"

 

Check out FBD. Farmboys Diesel. By far the best bang for your buck. I'm ordering up my 5" this week! Excellent prices that you wont beat anywhere else

 

thanks for the advice and yes it is a 4" stock it was a mess up on my parts

 

5" MBRP turbo back...love it, nice easy bends,,,its a long way to the back on a mega cab...it's sounds sweet...the neighbor swears I stole a highway culvert from somewhere!

 

Silverline has a bit more sound to it since its a straight through muffler. MBRP is a little quieter in my opinion. But if ur looking for a better bang for your buck id go with MBRP.

 

I had mbrp 5" and it was nice. Switched to silverline 4" duals and it's nice also. Either company is nice and easy to install
