Muffler delete, dual resonators

timber74wolf · May 20, 2017

I know everyone has done the muffler delete and run just the resonator with and without the flapper, but has anyone run dual resonators side by side with and or without the flapper with dual tailpipes? Just curious is all.

I've never seen that before. There was a guy on here that moved the resonator to the stock muffler location then put a y after it to dual tips. It sounded really good, and he was really helpful with videos he posted. I can't remember his name, but I'll look later, and see of I can find it.

I'm waiting for a guy at work that has a cat back to cut off his resonator from the stock exhaust. I plan on having an exhaust shop bend up duals with the stock resonators as mufflers.

A resonator is just a glorified straight thru muffler - so yes many duals have been done with straight thru mufflers. Or with Flowmaster chambered mufflers.

Have you heard of Kinney's also in Texas - sick dual systems........

Did he leave the flapper valve in the system somewhere? Also did he have the 4 cylinder mode tuned out? Looking forward to seeing the videos and reading his posts.

So you are going to run 2 resonators... Are you going to run true duals or just split after your y-pipe into the 2 resonators?

Yes, heard of Kinney's... Seen their work on YouTube.

I just got through a while ago cutting a side of 1 of my spare resonators off. I had 2 systems, but have sacrificed 1 to modify my Gibson system I have on my tuck now. Anyhow, I cut roughly 1&1/2 inches off 1 side of the resonators to see what was inside. Also so if I decide to run them side by side I am going to weld them together forming a figure 8. So cutting 1&1/2 off either side of the resonators will allow me to keep the tailpipes close enough to each other to look good instead of a huge amount of space between them. And they will exit in the stock location.

So the big next set of questions is this:

1. Obviously has anyone ever heard of or seen someone welding 2 resonators together that have had the sides cut off?

2. do ya think the 2 perforated pipes and sound dampening material will cancel the sound out?

Oh and it will be dueled after the flapper valve. Its a lot of work, but I am just brainstorming and seeing what the forum members thoughts are.

He ended up deleting the flapper too on his final version. I can't get the post to share here but go to the search function and type "bigham16" on the author search. You'll see a post called "GM Borla vs muffler delete." It's 3 pages long and all his videos are in it. It sounds really good. I did the muffler delete because of his videos, and saved myself a bunch of money towards my procharger.

Just split before stock muffler area. Not sure how it will sound, but the $0 cost of mufflers....

Okay, so basically what I am thinking of doing, but I am slicing the sides off the resonators and welding them together to keep them in the stock location. I'm curious as to see how your setup will sound. Do you have the 5.3 or 6.2?

timber74wolf · May 21, 2017

Alright, thank you. I will take a look. How do you like your pro-charger?

It's not installed yet. My wife found out she needs surgery so I'm going to get that taken care of first.

timber74wolf · May 22, 2017

Yes, you better take care of her surgery 1st. That's a priority. The charger will be there waiting on you.
