I had dual flowmaster 40 delta flows installed on my true dual system. It does sound nice, but has a weird drone at low rpms. Kinda sounds like the v10 with an exhaust. Its hard to explain.

How much louder are original 40 series over the delta flow version? I have the old original 40's that i chopped off my old truck sitting in my garage. Im thinking about having them put on instead. Will i see an increase in loudness and change in sound overall?

 

original 40 is much more throatyer than the delta flow..

 

Yup, I agree, the reason for delta's was lower interior resonance, with the original's, more sound inside/outside. I haven't heard a delta flow on a truck, but think I know the v-10 reference you mean, and yes, the originals will fix that.

 

yeah go ahead and grab a origional 40, if ur still in the return policy you might be able to change mufflers free with the cost of shipping?

 

im definitely swapping the mufflers then. I was thinking imco extreme but dont want them that loud.

 

Well I ordered my exhaust, I got the Cherry Bomb Extreme SI/DO “A.K.A IMCO Extreme” & two 22” X 4” stainless steel tips from Ebay for 100 bucks. Now, I just gotta get time to go the exhaust shop. Can’t wait! Sure hope it's loud enough to cover up my mud tire hum!!

 

I got the Roush dual exhaust on my truck with no cats and it still aint as loud as my tires goin down the road.

 

Wich system is better the roush off road or flowmaster 40? thanks RG

 

HOLY CRAPMAN!!! the sound is awsome at idle & WOT. This will get me in trouble!! And no more tire roar either. It has some minor poping & cracking when I let off the throttle. But that is a plus in my book. Thank you Cherry Bomb!!!! She sounds like a truck now
