TRD catback system muffler question

Oh the resonator is the "silencer"... they looked pretty close to the same thing to me and made me wonder what that part actually does!?? I'm guessing there's a resonant frequency generated by the intake??? Sometimes those type of things cause problems and why there's a resonator there in the first place eh?

 

I wonder if it's really necessary or if it's an emissions requirement. My thought was to cut it off, seal it, and then put the resonator back on so it looks like it's there

 

What part are you referring to as the resonator??

 

Part # 3 and it is to reduce sound only. No EPA requirements.

 

I was referring to part #3. Want that thing out of here

 

Not to thread jack but I have the stock air I take on my 2016 trd sport but have considered getting the pro intake. Would
I gain anything out of this change or just a few fancy colored letters under the hood?

 

My guess is any gain would be really minimal. Just some cool fancy colors under the hood. There's probably a lot more productive things you can do for $450...

 

You can have the TRD intake for a lot less if you buy the parts seperately. This is 277 plus the filter.

I have the TRD intake and a MagnaFlow Cat back... + Pro Grill: SOP Dyno.. +40... fun factor +100.

 

So on a stock truck with intake and exhaust you got +40 hp on the dyno?

 

On the butt dyno +40....actual dyno 2

 

^^^ That... Seat Of Pants AKA Butt Dyno..... numbers confirmed and posted!

 

Do I need all those parts.

 

What is Dyno?

 

Dynosaur?

 

Main purpose of the resonator is to control sound. However, there are all of these theories and what not about having "vibrating air" or something like that in which resonators can help with. But, the main purpose is to decrease sound. A straight pipe from the intake to the throttle body will be the loudest while any resonator installed along the way will quiet it down. Of course, resonators mean less air flow as air travels into the resonator on its way into the throttle body.

 

Yes, if you want the TRD performance intake system as they work together. This is still a lot less than the 475 retail price.
