I want to put dual exhaust on my stock 98 4.0L. I know someone that has a 40 series flowmaster not magnaflow and was wondering if anyone has done that and if it will make mpg changes or performance? And how big of exhaust should i get?

 

SEARCH!!!

You will gain dB, but not MPG or noticeable HP. Buy an exhaust for sound and looks, not performance.

 

I'm converting it to dual exhaust and i can't decide between the standard 40 series, the super 40 series, or the 40 series delta flow. Check it out and let me know what you think. Standard 40 super 40 or the delta series

 

i had a flow super 44 dual out the back, sounded real good

 

I have the single in dual out mag system. Go to my web page then clink on the exhaust page. When it loads you'll hear what mine sounds like.

Since the sound clip, I've added tail pipes that exit behind the wheels. I like this much better. It's quieter in the cab. No more droning above 2500 rpms.
Still has the same sound... just a little quieter outside and much better inside.

how would u guys think a true dual system running a x pipe and dual 5/8 magnaflow mufflers sound on a ranger?

 

someone on youtube ran true duals on their ranger.....didnt really notice a difference in sound.
