Brera V6 Exhaust Rear Resonator Delete

Hi everyone,

Thought Id put this in its own thread to add to the knowledge base for future reference for others. Id originally posted it in response to an air filter replacement thread but thought it might get a bit lost.

Anyone wanting a loud Brera or thinking of a sports exhaust, this is the sound of my manual 3.2 V6 without rear resonators - just pipes:

I couldnt find anything like this recently when evaluating muffler options so it might help someone else later down the track.

In addition to the muffler delete, I have also replaced my OEM intake with an Apexi power filter (pod filter) which is a dry type filter no need to oil etc. Sounds freakin great at wide open throttle coming up to redline.

I think its excellent - People that hear it love it - definitely loud, but not too loud (except the missus who sometimes complains). And bang for buck i reckon it's hard to beat!!!

Took it to the Pasta Run a few months ago and one of the guys in a 3200 Maserati I was chasing came up to me later and said he kept hearing this car and was looking for a Ferrari but all he could see was the Brera (true story).

The one thing, if you have the car under load (say up a hill) with the windows closed, going 90 - 100 kph, in 5th/6th gear, it's possibly a bit too noisy. Other than that - bloody nice.

Big thanks to my mate Chris (usually hangs out at Ausalfa ugame) for editing the video.

This ones got lots of revs in it doesnt exactly replicate your everday driving - Ill try getting another vid maybe up in the hills with a better audio too.

Hi.
Very interesting.
Do you have any photo of your changes?
I'm looking to do the same thing or to empty the two terminal exhaust...
Thanks

Here you go - some pics from a few different angles. Mine are 2 x 70mm staggered tips. They are good quality tips, double walled - not sure what brand or what the exact term they use to describe them, but they are "thick walled" (maybe 5mm?) not just pipe that's cut and chromed.

159 3.2 Q4 lusso

i've got a 159 3.2 Q4, would it be a safe assumption to think if i done the same to the159 i would get similar results? im looking to just exsentuate the engine noise and not get a load of drone.

Yes, the Brera & 159 exhaust systems are very similar for the V6, besides from the Brera having two small tailpipes at each side and the 159 having one large tailpipe at each side. What you're looking for is a pair of these from Wizard Exhausts:

Dan, you mentioned you didn't want to get a load of drone. I can't comment on the wizards, but deleting just the rears like mine does give some drone.

Is it Excessive? That's subjective, I don't think so, but the wife whinges it is too loud (which I also disagree with!).

I sell them, and have fitted quite a few pairs. They're a lovely fit and sound great for such a cheap upgrade. You might notice a little boominess at low revs but its very much something that you can drive around just by altering when you change gears. There isn't really anything you can do about this, other than using backboxes with resonators inside, but this would at least double the price. Even just simple motorbike style silencers behind the tips don't eliminate the boominess, this was the first thing we tried. They just make it quieter but at the expense of the rev range, as with silencers fitted the boominess comes in early and fades out later, but is quieter overall. Any straight through style exhaust silencer will give the same affect.

Excellent description Pud. Thank you.

I was going to try that exact thing you describe, something like hot dogs (cherry bombs) to replace the rear boxes.

Won't waste my money now, cos I'm totally happy with the volume, (in fact would love more) but sometimes would like to drop a few dB at 2500-3500rpm under load.

I'm sure swapping the Brera for 360 would do the trick. That'd sound perfect between 2500 and 3500rpm.

Only thing that might be worth you trying is to install some quarter wave tubes, one on each side.
