ive had a silver bullet catback on my truck for about a year and i noticed it got louder and now when i let off the gas it pops alot. anyone elses silver bullet doing this?? im not sure if its been doing it since i bought it i never noticed it might have!

 

I have one and mine will "rumble" when I let off the gas, if the overdrive is off, but it does'nt really pop.

 

put a set of headers and high flows on there..........it will make so much noise you won't be able to ever tell what's causing anything anymore!!!!

I know from experience!!!

On a more realistic note.........check the pipes comming from the mufflers to the tips. Mine rotted in just over a year, and i hardly ever drive it in the rain and no snow. JDM now uses all stainless but it's possible you may have a piece that rotted out they may make it sound funky.

 

I second that, and LOVE it...

mine does a little at end of a run, but don't notice it during regular driving.
mine has been through 2 1/2 summers and I added the lt's & high flow cats this spring, did'nt really notice it till last half of the season.

 

You will get the popping sound when you have a small exhaust leak. Mine did the same thing when the collector gasket failed.
Check for any leaks.
