i put 1 40 series on thsi weekend with dual out the back and it is too lud on the hwy, i cruse at 75-80 mph and it is at it's loudist from 70-85 mph, sould i just leave it or go back and have a 50 series installed or will it be too quiet

 

do you have stock manifolds and cats? Regardless, the 40 series is known for its unnecessary loudness and drone. I'd recommend a dynomax race series multi-chamber or go with bullets.

For some reason Dynomax bullets, even though they are straight through designs, are aweseome for sound. I had 1 3", 18" long bullet on my LS1 and the drone really wasn't that bad. You could talk and listen to music easily, but you knew it was there.

I'm doing true duals with 2 2 1/2" bullets.

 

yeah stock everything, well i think 50's are the only way i can go with out spending alot more of my mom's money

 

I wouldnt go with flowmaster, but thats just me... there are other straight thru design mufflers that are way cheaper than flowmaster plus they perform better.... I would get magnaflow, borla, or any other straight thru design... I got the hooker aerochamber and love it..... not bad for $59....

 

Dynomax bullets are like 50 bucks for the pair man. They are cheap and perform

 

I run the magnaflow xfactor and love it. Isn't loud like the flowmasters and very little drone.

 

well could i get the bullets and have a y pipe that would attach to the the two tail pipes i already have? and how loud are the bullets i am looking for something quiet or quite on the HWY

 

Id get a Magnaflow. I have the smallest SS Magnaflow I could find 4x9x11 With the cats it sounded awesome. WHen I gutted the cats, it got raspy and agrivatingly (is that a word? ) loud. I just had a 3" bullet added, and ran the pipe to the rear instead of right before the rear tire, and it sounds much better. Killed all the rasp too. its still loud outside the truck, but sounds great inside the truck.

 

or no muffler , mine sounds good at highway cruise , you know its got a exhuast but doesnt bother you . i have a 3 inch off the cat-back to a y pipe for my dual tips . i had awesome power gain i ran two tenths faster with just this at the track and price was good . ill change once i go longtube and catless to magnaflow

 

well could i add a resinator or a bullet infront of the 40 series and quiet it down, i would think that would be the easiest.
