i'm thinking about doin it.

bypass the resonator with a pipe.

i'm worried it's going to sound raspy - not too worried about being louder.

any thoughts?

any one do it yet?

 

What exactly does this accomplish? are you looking for more horsepower or more decibels?

 

I wouldn't. It's loud enough IMO.

 

It would definitely sound raspier.

The resonator's job is to mellow out and lower the tone of the exhaust note to something more tolerable to the human ear. The muffler then silences this new tone. Resonators use a chamber or series of chambers whose dimensions have been chosen to correspond with the volume of each exhaust pulse from each cylinder at each spot in the RPM range to accomplish their mission, much like the large bell of a tuba produces a lower, mellower tone than the small bell of a trumpet (ignoring some other factors of course). Mufflers will generally use baffles, but sometimes just pass the exhaust through the center of a silencing media in a straight-through fashion. This is why straight-through mufflers tend to do a hell of a lot less muffling than baffled mufflers do, yet also create significantly less back pressure. I am unsure of the design of the Comptech catback's mufflers.

In any case, removing the resonator will do little to affect backpressure as the mufflers will more often be the bottleneck in the tract unless they are straight-through like in the case of the GReddy Evo2 catback. Of course, discounting any other mod, the OE cat is the largest bottleneck by far and any change to the catback without first eliminating the restrictions in the header and cat will do virtually nothing from a performance aspect.

Personally I wouldn't touch the resonator - ever - unless I was going for the coffee-can-axleback sound that can be heard in such locations as high school parking lots.

 

Sad but true

 

Icebox

 

what does an icebox have to do with anything?

 

thanks man.

i was thinking that the resonator was another restricting element, as the cat.

my plan was to get a high flow cat and remove the resonator on the comptech exhuast.

we'll see, im gonna check out a muffler shop tomorrow.
