iam thinking of getting a muffler delete pipe for the truck will this void the warranty

The factory resonator on my 06 is right in front of the rear end where it starts over the axle. It is about 7" in diameter and about 10" or so long.

'just inspected mine, down pipe, kitty, muffler, over rear axle, tail pipe.
No OEM resonator.
They must have left mine off.

I wonder when they started installing resonators away from the down pipe? I bet that makes for a cluttered exhaust system… cat, muffler, resonator.

If you take off your resonator, I would keep it in the garage for a while, just in case you get a drone you can’t live with. Resonators are expensive to replace.

From what I’ve seen (one aftermarket resonator) resonators look like small straight through mufflers.

I need to get rid of my stock muffler to keep my EGT’s lower. I hope I don’t get the dreaded drone with the Banks! If so, I'll fork out the money and get a resonator.

I have an 06 and I don't have any resonator over the rear??

I have what I thought was a cat converter (same place as the resonator on my 2nd gen), but it is up front not far from the downpipe.

I have the RPM delete ,and was going to install it myself,after reading on here someone getting in installed at a Muffler shop for 40.00 bucks,and 30 minutes of dinking with it ,thats what I did,and had Lunch while I waited(time management)

I try to do all my own work ,but I've learned I don't do Mufflers

Now with the Delete,K&N Air intake and silencer ring gone ,it sound's like a "Jet" engine under the hood ,I'm a 49 year old kid and I like it

Maybe the resonator is Mega Cab only, or possibly after a certain build date? It tucks up around the rear end nicely.

Can you here the turbo alot more with just the muffler gone? I had a 5 " system on my 05 . The kitty was gone on it but had a straight through muffler. You could here the turbo out the exhust wih it.

Maui Steve

I did not notice any notable change in "Turbo noise" with just the delete pipe,but when I did the K&N air intake and removed the silencer ring ,it made the Turbo "Sing"

Nope. Now local law enforcement MAY have a problem if they are arseholes

darrenb

does removing the cat, cause you to lose some bottom end performance? is keeping noise level down and warranty in tact the only reasons for leaving the kitty alone?

You won't be sorry...

So lemme get this straight. For about $80 I can just delete the muffler? Why would I pay $400 for a cat-back system if I can do the same thing for less? Is there a benefit to the $400+ cat-back systems such as power/temperature (looks aside) that the simple $80 mod will not get you?

Depends on who you ask. The factory 4'' system flows pretty good when the muffler is gone. Unless you are making really big power numbers it will get the job done.
