'04 545i VAREX X-FORCE Muffler Installation
 

Good morning everybody!

I thought I'd start this thread for all of those who are curious about the VAREX Muffler.

When I first bought one back in '08 for my E46 318i I was a bit hesitant about its ability to be able to baffle the exhaust enough to sound 'near stock', but I was surprised with the result, and I'm now purchasing another one for my 545i.

There isn't too much information available for BMW owners who want one of these installed... so I thought I'd share my experience.

the website is here: XForce. Performance Mufflers, Exhaust Systems & Accessories. About the Varex™ remote controlled Sports muffler.

I just purchased the 3" inlet / twin 3" outlet and I'll upload pictures and a video when it arrives and is installed! I'll also be doing the wiring myself and will provide pictures of this :)

Being able to have the throaty V8 sound or quiet cruising at the press of a button is a winner in my books.

Stay tuned!

Looks interesting. Looking forward to the video. :)

+1 I'm excited to hear this. IF you have the ability to control the volume, I assume you will delete the muffler and the resonator?

If removing the resonator will give the car that Bitey V8 sound and gurgle, then YES!!!!!!!! I never thought about it until you mentioned it just then.

I'm not after a ridiculously loud exhaust, just one that has that classic V8 bite and gurgling :) Any input on this would be greatly appreciated :)

Deleting the cat's and installing headers will get you that bitey v8 sound for sure. I wasn't satisfied with the v8 sound with my car until we did the headers but I do recall some really subtle gurgle (and maybe even a little pop) even when the car had catalytics. I've posted this video a few times on the forum already but here is a video with stock manifolds and catalytic converters still in the car before the headers were put in. Forward to 19 seconds for really subtle gurgle.

That sounds great West, Cheers for the Video :)

I'd certainly be happy with that sound from my car. I mean, it is going to have a baby seat in the back....

Excellent. Keep us posted!

Removing the muffler like I did gives the car a great sound, but you are adding a muffler so yours will be subtle and quite unlike mine. This is why I recommend removing the resonator which will make it louder but then you can dial it back to a near stock sound.

yusoslo that sounds awesome! had that great V8 gurgle too, I might give just the high performance varex first, then if its not as v8 sounding as i thought i'll get them to remove the resonator, the local muffler shop 1km from me only charged me $150 for the muffler delete, including a polished SS twin tip!

I'll keep this thread up to date :)

The muffler arrived today! very fast postage considering it was free :)

It was very well protected in the box. And the welds look great, twin 3" is going to fit snug in the bumper cutout!
