Yes Another Exhaust Thread

slimcubby · October 18, 2010

Lol hey guys,

I am debating between muffler swapping for a flowmaster 40 series or possibly going bolt on. I had an 09 F150 5.4L with just a muffler swap flowmaster 40 series and the sound was pretty nice. Not much drone at all and didn't set off car alarms when driving. I use my truck for work and drive from house to house cleaning pools. I don't want anything to be obnoxious but do want a better sound than the stock setup. If anybody has any recommendations please let me know. Also, has anybody notice better or worse MPG with their setup?

Thanks!

theres a big thread on here that actually lists how well each different type of muffler flows, i dont remember much about that list except for that flowmaster was the worst.

The Flowmaster 50 series is a nice muffler if you want something with better tone than stock but not real loud. I have one and I like it a lot.

I hated flowmaster on my 03 5.3. It droned in the cab, lost low end torque and mileage, and it rusted out in under 2-1/2 years. I'd recommend Magnaflow over flowmaster anyday.

I agree, I'd pass on the flowmasters, and go for a magnaflow, borla, or a dynomax model

I did a few searches.. Do you by any chance remember the title of that thread? That would be an awesome thread to help me with my decision.

i dont know how the flowmasters will last, but i have them on my current 2001 silverado 5.3 and i am very happy with the sound. not to loud, not to quiet, very little if any drone, perfect...

Agreed. If I remember correctly Kevin installed flowmaster dual exhaust (40 series?). He isn't bothered by the drone of that system and I have a 50 series muffler which is even quieter and I am not bothered at all by it, it sounds perfect. Drone is very subjective. Everyone has a different standard of what is tolerable. The biggest concern some people seem to have are with rust but that depends on where you live. If you are up north that may be a concern. I don't know where the OP lives but I don't have to worry much about rust since I live in Georgia. It snowed here one time. Well it was either snow or the stuff they spray on the runway before jumbo jets crash, not really sure. Oh well.

yeah i have the 40 series... its perfect imo. i sprayed clear engine enamel all over my exhaust/muffler to help prevent rust as the winters up here get very harsh. we will have to see how my flowmaster holds up to its first winter.

I did the large body magnaflow. Good sound, little to no drone (when empty or no trailer). If you are thinking this will make any signifcant change to mileage or power, move on to another alteration. You will never recover your money in fuel savings this way.

Nah I don't really want the "gain" in mpg from this I just don't want to lose MPG for upgrading my exhaust for better sound.

I used to be a flowmaster guy.. but my favorite is borla..top qaulity with a sound that will seperate you from other guys..also magnaflow has nice products,comparable prices and a nice sound..

just my opinion.. hope it helps, let us know
