I had the Madness Autoworks Monza Exhaust with carbon fiber tips installed last Friday morning July 28th. I wanted to give a little time of use to make sure there was no rattles or issues before posting my review. Also I have not received anything from Madness for this review, it's completely unbiased and 100% my opinions. Unfortunately I had lost my DB pics and video the day of the install, user error. I have an app called Decibel 10, which seems to work pretty good for a free app. One of the mechanics at the shop had a Mazda GTO with a Corza exhaust on his car and he asked me to use the app. His exhaust was way to loud at rev we got 132 decibel reading at rest it was 119.

First let me say again this Monza Exhaust is awesome and worth the price. The mechanic with the Mazda even committed on how well the Monza was built and he absolutely loved the carbon fiber tips!

Anyway first thing this is not a DYI project that just installs in minutes. It took 3 mechanics at certain times to adjust and get the exhaust onto the hangers. They also had to make a slight modification to the drivers side rear hanger they had to cut about 3/4 of inch off the steel post to get the exhaust tip from rubbing on the rear diffuser. It took them every bit of a hour and half from start to finish to install. They charged me $200 to install it and yes I had contacted my dealer but they refused to put any aftermarket parts on the car.

The reading I was getting on the standard exhaust was high 60's decibel like 68-69 was normal at idle. Throttle put the reading at low 80's the highest was 82. I think most standard luxury sport sedans have an idle reading in the high 70's and throttle in the low 90's.

With the push of the red button (yes I replaced the black one) you can hear a noticeable difference between the 2 exhaust. I mean it's like night and day. Now the Giulia has awaken from a dismal sleep and she sounds like a real sports sedan is suppose to. I also took it by my local dealer and they were amazed at the difference. It's not as throaty as the QV and it burps a little more, however it doesn't get drowned out like the standard exhaust does it holds it's own now. There is zero drone effect in the cabin, and its very comfortable sounding inside with the radio on or having a conversation. For me the biggest difference is at start and laying on the throttle she seems to have more character and more pep. I don't have any numbers to support the more pep I'm just going by feel, she just seems to have more power but that could be just psychological.

I HIGHLY RECOMMEND THIS EXHAUST. I love it and I have even gotten more comments from bystanders on the sound, had zero comments before. I will also post a video but here is some pics the first is inside the car at idle. The second pic is outside at idle. The third pic is at rev, the highest reading was 112 at rev. 4th pic is inside driving radio at 20. 5th pic is driving radio set at 28. The other photos is of the standard exhaust with the FAKE tips, just for reference. So this exhaust is not over the top 18 year oldish excessively loud. IMO the standard exhaust was non existent and added very little to the overall experience, now I have all the senses covered Sight, SOUND, Feel, and Smell. Did I mention the Carbon Tips? Just WOW......

Been looking at it. Does it void the warranty?

NO it does not void the warranty of the car. However I no longer have a warranty on the exhaust from Alfa Romeo. It does not effect any other warranty items.

Heard the Corsa exhaust and yours blows it away. You pay for what you get.

Thanks for that write-up. You totally helped me decide. I was wondering about the tips too. Sounds like the carbon is the way to go.

Yea the other cool and deciding factor for me between the Madness Monza, Corza & Ragazzon exhaust was the flexibility in interchangeable tips. I can easily swap out the carbon fiber tips for chrome or even blue tips if I want. I had Corza exhaust on a previous vehicle and really liked it, it was high quality and sounded great. I listen probably over 100 times the you tube videos of the Monza & Corza and for me I thought the Monza sounded better in the videos, just my personal opinion.

How were you able to compare it if the Corsa exhaust is not yet available? The major difference between the Monza and the Corsa exhaust is that Monza is a 2.5 catback exhaust while Corsa is a 3 inch catback exhaust system. The wider pipe will enable a deeper sound which I personally prefer. Although the Monza does really good also.

I don't think you can go wrong with either exhaust. Both are great products and both will add that exhaust note that seems to be missing with the standard set up and the fake tips.

I think Alfa55 was referring to the videos that are out on both exhaust. I agree with him after carefully listening to both over 100 times I thought the Monza sounded better. Maybe it was the production of the video, I don't know. Like I said before both exhaust is a vast improvement over the standard OEM and no one can go wrong with either IMO.

Exhaust note is of course of personal preference. But we can definitely agree that either system is a vast improvement over stock.

Do you think it would annoy wives/children/elderly when they sit in the cabin? They have a lusso option the video madness put up was worthless in understand how different they were other that it's more "refined" and that it's a 100$ more.

No IMO it would not annoy anyone especially children. For normal driving with the windows up, radio on and a normal conversation you can't even tell. However when you apply that throttle you can hear her. My mother who is 67 rode in it and we were having a good conversation and the exhaust never interfered with it. I did have to turn down my radio for her. LOL

Listen to the sound clips, that's what I did. I'm waiting for published dyno results from both. Sometimes larger diameter pipes can hurt performance as the back pressure could be reduced. Madness seems to have this covered.

That statement couldn't be any more wrong.

(Excessive pipe diameters create excess volume which diminishes the kinetic energy of the exiting exhaust which is already losing energy as it cools, this is really what tends to hurt exhaust performance when people go oversize too much on naturally aspirated cars... not as much of an issue on a turbo car, after the turbo)

Thank you for your review!

Really appreciate the feedback and glad to hear you like the exhaust.

A little concerned about the install time and the challenge the installers seemed to have. The units are designed to be adjustable due to the joints we have designed. This allows the installer to have plenty of room to adjust the unit as needed if there is a bit of variation in the vehicle built. Typically you should be able to move things around a bit and get everything to line up correctly. The key is to not tighten anything until the entire unit is on the car and lined up. Then once everything is lined up the exhaust clamps are tightened one at a time. This really helps.

We typically charge 1 hour to install the unit and it is done with one tech doing most of the work. Then we have our Shop Manager do a final check and adjustment to make sure everything is lined up properly. There should not be a need to cut anything.

However, it is already done and installed and you are happy. We are also happy to hear. For those that may be having a shop do an install in the future here is something to note. If there is ever a question please have the installer call us. We regularly talk to other shops and give them some guidance on installation and can usually save them some time and a bit of frustration.

Again, thank you for the review and your support.

I took it to Import Specialists they have been in business for over 35 years and specialize in foreign cars. They have worked on everything from low end to high end imports. I just gave an honest and unbiased review. I stayed at the shop the entire time and stood outside the service bay and observed everything they did. So this is coming from first hand, matter of fact the mechanic and shop owner both had to show me what they had to cut off in order to get the tip from rubbing, they tried several different things to get it to fit, that was the last resort. I personally didn't see any other options for them either. Again just an honest, unbiased review.

It sounds amazing though.... I still highly recommend..... Oh yea did I mention the carbon fiber tips..... WOW
