muffler
 

whats the best muffler for my 4.0 l?

Borla Pro XS... hands down the best sounding muffler i've heard for an SOHC. Had one on my old truck, going to have one on my new truck.

have any links i can order off of?

i can get it for you if you give me a part number, you can get the number off borlas site, www.borla.com

borla or magnaflow are both good choices!

I personaly reccomend FlowMaster! If you want sound go with FlowMaster, FlowMaster saves me anywhere between 1-3 mpg depending upon how hard I drive. You can orer them off of thier website I think.

I'd say flowmaster. The 40 series sounds really good on an SOHC.

ive heard borla and flowmaster 40 and there both really good.

I have a 02 4.0 and I had a Flowmaster 40 series put on it and noticed no sound increase. The trucks have to many CATS on them. If restricts the airflow to much before it gets to the muffler. I run straight out of the CATS into duels and it sounds great.

i definately noticed a sound change with the flowmaster 40 on my 4.0, and i hated it. im sticking wtih magnaflow from now on, though i would trust borla too

I doubt an exhaust is going to save you 1-3 MPG...

Do you have any other mods that would of helped your MPG?



Borla and Magnaflow is probably your best choice for a 4.0

Right click save as the click in my signature, i have a Center/Offset Borla muffler..

I'm just gunna pop in here a give some support to Gibson. :006: It's just a little louder than stock, and has a nice deep tone. Which is what I like! :approve:

i lost like 1-2 mpg cause my exhaust lol but hopefully the new air filter and intake i get from K&N will give me back the 2 mpgs i lost when i got the exhaust on, but im happy with the exhuast sounds nasty and you can deff here it comin down the street and its faster as well to
