Hey everybody. I like to give my 400 a little more volume on the exhaust. I have been listening to a ton of clips on you tube with the resonators deleted. It sounds great but it pretty loud. I look under the car and saw how long the stock ones are. I was thinking If I replaced them with smaller ones (look at ebay link) would I get a nice in between stock and full removed?

I was told that just deleting the rear resonators is not as loud as deleting all three..

I'd like to do this option as well just haven't had the time.. Should be around $75 for the shop to cut and replace
with straight pipes..

Some people may not want to lose their rear cans though.

Im am looking for a mellow v8 but about double the volume now. what do you think would be the best way to achieve this

Wonder how the 400 sounds with only that small resonator taken out?/

I actually meant to make a thread about that. But I have removed that small resonator and I thought it wouldn't change anything. But it definitely added a nice tone to the exhaust. I think everyone who is thinking to have a slightly deeper and sportier sound, but not something too loud, they should try that. I definitely love how it sounded when i got it done.

On my gs3, I have a custom catback with deleted resonators, its quiet at idle but throat at WOT that you wouldn't think it's a i6.

does anyone know the stock exhaust pipe diameter for the gs4?

try this, unbolt the mufflers only and listen to it, if you like it which you probably will just get some pipes welded with flanges and some real nice tips and call it a day, thats what i did and i love the sound plus i can always just bolt on my old mufflers if i want to.

The OEM rear mufflers are packed with hi-temp fiberglass plus they are HUGE so that's why your exhaust is so quiet.

I replaced my rears with Magnaflows and some bigger Magnaflow chrome tips that fill the bumper cutouts much better. The sound is excellent - mellow on easy throttle but I can really hear them when I'm on the gas.

L3XTOIC, please post a clip of your exhaust. Hard to find a good GS3 set up.
Thanks

how would a HKS Hi power exhaust sound on a gs4 only replacing the rear and leaving the rest OEM (sorry for thread jacking)

Remove all 3. It will sound amazing and still quiet enough when cruising.

i removed all there n added RMM mufflers.

its silent cruising on the freeway n nice n throaty when gassing. its quite raspy when the exhaust is cold but sounds better as you drive n warm em up.

i have exhaust leak.
