Hello guys, i recently installed the Lethal Performance O/R H Pipe on my 2011 Manual V6 and let me tell you that this thin is LOUD!!! At idle sounds amazing but its when you get to the 3K RPMs that gets raspy as hell. I was told to install/weld resonators but it doing research i see that some people installed the 1792 vibrant resonators and some did the 18" glasspack. Does anybody know which of the two gives you a deeper tone? Glasspacks are cheaper than the resonators and i can get them here locally but i want to get whichever its deeper. Thanks guys!

 

Something to keep in mind while deciding is that glasspacks don't last. The resonators are more of a long term solution. Glasspacks have to be replaced every so often because the fiberglass will eventually break down and work its way out (fur ball / hair ball).

 

I put glass packs on my F150 4X (4.9L I-6) back in 1988 - 130,000 miles ago. Still work fine. Love the mellow tone.

 

So are glasspacks deeper? Or no difference?

 

Glasspacks only last about a year, google that to confirm. Sure, you can keep em installed, but they will never sound the same.

 

Glasspacks work wonders

 

I want to remove my resonators on mine.....open my pipe up more and let my borlas rumble more....

 

im in the same boat. glasspack seem to sound better, but im worried about how long they last. im leaning towards the magnaflows on AM

 

I've got a friend who got a second set of resonators and had the factor GT tips and muffler hangers welded to them, along with the GT inlets and has them mounted in place of the stock mufflers. Looks stock and sounds great.
