Has anybody cut the resonator off their oem c6 airbox (2008) ?

If so, how do you plug the hole thats left ?

Did it throw a code are cause any negative issues ?

C6Whatever

I'd be interested to know too

I was thinking about it but how would you seal up the hole and not worry about any part of the seal coming loose and getting sucked into the engine.

I bought a LS7 on ebay for $35, question solved.

LS7 for $35..wow what a deal....lol

I was thinking leave a 2" piece of the extension that connects to the resonator on the oem airbox, cut it of smooth, go home depot, find a abs plastic cap like a plumbing fitting, or drain line cap, use GOOP and fit it over the extension/hole.

Nothing can get sucked in if you use a cap.

i have 4 or 5 stock z06 intakes laying around much easier and better looking then trying to home depot your ls3 intake. shoot me a pm

That Helmholtz resonator is there for a reason. It enhances performance. Why would you want to cut it off? I am just curious, not being combative.

snake oil hack it off, why would the LS7 not have one if it increased performance...think about it, but not to hard lol.

I offered one of the members here $65 for one and he turned me down, so off to ebay I went at almost half my offer. Why is it that a lot of people think that their old Junk parts are Golden? I buy most of my stuff from ebay because of that.

it does reduce noise you hear in the cabin of the car. but i like the way a v8 sounds so the chamber sucks get rid of it. let me hear that engine roar.

I have one that I would let go of as well.

Go with the LS7. I got mine off ebay and it had a K&N filter. I needed to use the LS3 flexible throttle body connector.

I would change your restrictive air filter instead....

The two things that GM is always trying to remove from the Corvette are weight and cost. If the resonator wasn't doing some good, they would certainly delete it.

It's there to reduce noise.Others on here have taken them off in the past.I'd just cover the hole with duct tape for now until you come up with a solution for the hole. I think you can pry it off actually.

It's interesting because the LS3 assembly with the resonator is cheaper to buy than the LS7 without the resonator. As far as I know the parts are identical except for the resonator - you pay more for less on the LS7 part. I guess there's not only a Corvette Tax but also a Z06 Tax on top of that.

ls1121

they did on the LS7

R&L's C6

NorthTXC6

I did the same thing, replaced mine with a Z06 box 20k miles ago and never have had a problem....

Sorry it took me so long to get back to you, pm sent.

FWIW, i did replace the oem the 2nd day I had the car, Attack Blue from TKO, Performanceere a great vendor here on the forum.

I really like the Attack Blue design.

Sevinn or anybody that wants to sell the zo6 intake, you can call me at (561)305-2428

Im not afraid to give the world my phone number. Should I be ?

Thanks,
Steve

Sorry about the size of these images, I'm not good at shrinking them.

Heres the oem stock airbox, with heimholtz resonator;



Heres the oem stock filter;



Heres the Attack Blue oem replacement. Sure looks less restrictive.
