new exhaust sounds too poppy
Thank you to all who replied to my question about new exhaust sounding to poppy.After trying most of your suggestions I decided to cut the exhaust off 3 inches after flowmaster.Not only did the poppiness dissappear but it also took care of a sluggish off the line problem.Who new .Im still in a state of WTF? never realized that 2 extra bends in my exhaust could cause so much mayhem.Anyway am going to put 3 1/2 feet of straight pipe out the rear of the truck and see what that does.Will keep u all posted thanks again

Re: new exhaust sounds to poppy
I just turned mine down right out of the flow. I have been running like this on all my truck for the better part of 10 years

Re: new exhaust sounds too poppy
Hmmm wonder if that's whats causing mine to be sluggish at low rpm levels.

Re: new exhaust sounds too poppy
Headers are 1.75" tube out to 2.50" exhaust to delta 40 flowmasters just beyond the cab. The tubing is 16 gaugealuminized steel.
