About a month ago I had the resonator removed from my 2004 MC 40 JCW.
Just wanted to say I absolutely love it.
I did a lot of research on what others had done and listened to a few sound clips.
I just thought the stock sound was OK but to muffled.
So I found a good custom muffler shop near me and took the car in to get an estimate.
The price was right in the ballpark from what guys were saying it would cost on the forums.
They did an excellent job and it cost $100.
Best $100 I have spent on the car in my opinion.
It took about 1HR to do and when the owner came out to tell me it was ready he said you are really going to like the way it sounds.
He was correct.
Not loud at all but much more agressive sounding.
Color me Happy Happy Happy. Dave.

 

Any video or sound taken to show us?

 

Do you think this is worth doing? I've been on the fence about taking my '11 JCW to delete the resonator as well and everyone has told me to just put in a new intake. The resonator delete sounded appealing because of the price.

Someone told me it would make the car sound like a ricer... Do you think that's true? :/

 

I will try to get some video or sound clip.
I have only heard sound clips of the newer JCW exhaust with the resonator delete so I can't say what it sounds like on the street.

But I can say mine does not sound like a rice burner.

I think the resonator removal allows the cylinder pulses as the Pistons fire to get a more separated sound.
I am no audio tech so I could be talking out my .

I think the more devices like a resonator the sound has to pass through the more the separate pulses are lost.
I like the sound of hearing each piston fire.
If you like the show Wheeler Dealers watch the Lotus Élan show and listen to the exhaust.
That is the sound I was hoping for. I think it's close.
And I love the snap-crackle-pop as you back off the gas. Dave.

 

That's what I want! Forget people, I'm just going to do it. Definitely post a video/audio when you can!

 

Finally just bit the bullet and did it today! Someone on LXM said nice tractor, lol. While idling it does sound somewhat like a tractor haha. I'll have to see if I can somehow record while driving. Before: http://thundaga.net/?attachment_id=183 After: http://thundaga.net/?attachment_id=184

You'll have to click the link then click the next URL that ends in .mov to see the video.

 

Are you happy with the way it sounds under excelleration?
I would think the turbo on your car would change the exhaust note a bit.
I will get a friend of mine to hold my iPod to get some video as I excellerate away. I want to hear it myself. Dave.

 

From the inside of the cabin, I can say I'm happy. I'll have to get my husband to record while I speed away on our street for a video. I'd love to hear yours!

 

Alright since its just me and my myself and I don't have a fancy phone mount, here's a video I took from the inside of the cabin while revving it. Sorry it doesn't sound nearly as awesome as it could have if I had been standing behind the muffler.

Sounds good ! Thanks dude.

 

Sorry I couldn't get better audio!

The sound really is great though. Every time I speed up to get on the freeway and hit between 3-4k rpms, the sound is the best. I just want to speed around town everywhere to hear my own car now.

 

It sounds great.
Maybe a bit louder than mine. I noticed the others I have heard with the turbo engine exhaust have been I bit louder as well.

It is supposed to warm up next week it's 17 degrees now in mid nov.
I will get the video of mine then.
It's normally 45 now. Dave.

 

Here is a video clip. Dave.

 

Sounds nice Dave.. I might have to do this mod to mine now..

 

Thanks for the clip Dave. I'll probably get this done this week. Cheers

 

Just a heads up. I have an 05 JCW with the resonator deleted. I liked it before and actually thought it could be a little louder. I recently installed a RMW Header and now it is louder. Its the sound I wanted and you hear it in the car.

I use this car to commute in and run around town and stuff. I really like the sound when I'm driving by myself especially in the summer with the windows down.

But I took it on a three hour drive this weekend with my daughter in the car and it made me realize it may be a little too loud for most. Especially if you take long trips. It doesn't really drone but it is pretty loud at 70+ with any throttle fluctuations.

I don't have any audio to post and the car is getting repainted so I won't be able to take any for awhile. That being said I think the resonator delete with the stock header is a safe bet for just about anybody.

 

I had a shop make me a non-resonated mid-pipe so I could swap them as I please with a clamp. Definitely an improvement in sound, but it's still not loud at all. For $100 it was a worthwhile improvement over stock, I couldn't justify dropping $700 on an exhaust. I'd like it louder but for cost it'll do, I can get summer wheels and tires instead.

 

Hows the drone on the highway for a resonator delete on a JCW? I'm about to have this done, but I do a fair amount of highway driving..

Also, does this add any pop-burble on a pre-facelift JCW? I supposedly have the full 210hp JCW software (I do have blue injectors and airbox) but have very few pops like on my 05 JCW. Hoping to get some of that snap-crackle back.

 

Same here, watching.

 

Non-existent. It barely makes the car louder.

 

Does it add snap/pop? Change the tone? Whats the main difference?

 

The factory programmed run-off in my 2006 did increase in volume and harshness. I can't speak to whether it would add run-off to a prefacelift car.

It's slightly, slightly deeper sounding and it increased in volume an insignificant amount.

My wallet is $100 lighter.

 

Wallet weight reduction mod it is! Off to the performance shop! I'll do a before and after video..

 

I'm curious to hear your opinion on your own car. It isn't expensive but I probably wouldn't do it again because the car is still just way too quiet for my taste.

 

Quick review from a pre-facelift JCW with the full 210 HP kit (injectors, airbox, and software): Before, I had very little burble compared to my last facelift JCW. I definitely missed it popping between shifts, which was my main motivation.

It cost $107 at my trusted shop, and took 1 hour. They used clamps to make reversing easy, making this a very low risk mod.

I have to be honest, with the windows up there's not much difference until you get to 5000 rpm, then its a tad louder and raspier. No drone on the highway at 70mph. With the windows down, it snap-crackles in a raw and hilarious manner. Its louder, a little deeper, a little raspier at higher rpm, but still retains the basic sound of the JCW exhaust (which I think is perfect, but too quiet). I cant wait for the weather to warm up so I can keep the windows open!!

When the car is cold, the snaps are more prevalent, but once it warms up it settles down a little. The snaps are less frequent, but still really loud. Burble comes between shifts, on overrun, and while de-accelerating just like my facelift JCW. There aren't as many predictable pops/burbles, but almost as many as my facelift. My stock '05 JCW was more pop/burble while the 04 JCW resonator delete is more snap/crackle/burble/pop. I like. I like very much.

Great subtle, but seriously satisfying mod. It makes the JCW a little more antisocial, kind of like the Abarth 500 (which is actually a factory straight pipe - NO MUFFLER). I'll attach a sound clip, but I'll have to make the before from my previous facelift JCW (stock), instead of an apples to apples comparison due to poor planning.
