Borla40670 ProXS ProXS Muffler 3" Center Inlet/ 2.25" Dual Outlet, 4" x 9.5" Oval, 19" Long Body, 25" Overall Length. Universal Part. Reversible Design.

Replaced factory muffler on a 2014 RAM 1500, 5.7 hemi. Nice deep rumbling cold start.. Not overly loud at idle or up to 1200 rpm. Deeper and more "buttery" than stock.. At full throttle it's a beautiful howl. No rasp. Cruising at 45 - 60 mph it's almost silent in the cab but at a sustained 1500-2000rpm / 70-75mph there is a drone. Not so much that you couldn't hold a conversation but it's noticable. It is a flow thru, reversible muffler so you have to weigh the power with the noise..

Gives Chevrolet Silverado a good sound

Sounds pretty good. I put this on my Yukon which has the 5.3 and sounds good. At a warm idle it gets quiet but that will happen since it not pushing a bunch exhaust out like a built big block would but if you want to add more lower end tone to you vehical this is worth the money

Used as 2 in 1 out on 99 suburban, no cats, sounds great. Always a fan of borla, got a better sound then flowmaster for sure

It's great! I seem to be running a bit behind with these. My bad.

Wasn't a very good buy.wasted my money and time. going to sell it as soon as I get it off

Man dude this exhaust is great. I got 60 horse power from my dyno and the sound is crisp I love it. It was worth every penny.
