Dinan Free Flow Axle-Back Exhaust - 2006-2010 BMW M5 - D660-0009AOverview: The Dinan M5 Axle Back exhaust system provides maximum flow characteristics for optimum power gains while producing a civilized yet very sporty exhaust note that is appropriately aggressive at wide open throttle. And there's none of that irritating low RPM ''drone'' that is common with so many aftermarket mufflers. The mufflers are manufactured from 100% 304 stainless steel inside and out for maximum resistance to corrosion and nearly a 30%

Overview:

The Dinan M5 Axle-Back exhaust system provides maximum flow characteristics for optimum power gains while producing a civilized yet very sporty exhaust note that is appropriately aggressive at wide-open throttle. And there's none of that irritating low RPM ''drone'' that is common with so many aftermarket mufflers. The mufflers are manufactured from 100% 304 stainless steel inside and out for maximum resistance to corrosion and nearly a 30% reduction in weight eliminating over 20 lbs. The four 3.5'' diameter polished, or ceramic black, stainless steel tips not only give the car a more aggressive look but also feature Dinan's new ''Cool Tip'' design that effectively reduces temperatures in order to minimize radiant heat that can affect bodywork over time, as well as avoid discoloration of the tips themselves. The Cool Tips also avoid the possibility of a nasty burn while loading items in the trunk. Employing the principle of rarefaction, the design features an inner and outer tip with a vent at the base. When a positive pressure wave travels to the end of an open pipe and is ultimately expelled into the atmosphere, a rarefaction or momentary drop in the density of the surrounding air is created behind it. This momentary drop in the density of the air surrounding the pipe's exit creates a vacuum, pulling the air from the surrounding area to fill the void. The vent at the base of each outer tip then enables air to be drawn in effectively cooling the tips. Utilizing the factory brackets and hangers the Dinan exhaust mounts in a factory-like fashion for a perfect fit and clean installation.

Features:

  • More Power: + 9 HP @ 8000 RPM, + 6 LB-FT @ 8000 RPM
  • Drone abatement technologies used to reduce cabin resonance
  • Enjoyably louder, sportier sound

Great sound mat for the price!
Style: 50 mil 50 SqFt, Style: 50 mil 50 SqFt
This is a good product. Many people go with KILMAT because of the value to price point. I did as well. When you clean the surface (in my case it was all painted metal) this stuff sticks very well. I do recommend you use a seam roller of some type, I used Lumiteco 3 piece roller set. This will help with adhesion and mostly flatten the overlapped edges. It also helps you see where you have rolled as it leaves little grooves. The difference when we had no sound mats and after was very impressive. We haven't finished our install yet and it is quieter than when we had an interior in the van. There are thicker mats available in other brands, but this will work great for our van build, but this helps keep the weight down. It is quality material, just be careful when you are removing the backing, the edge of the foil face can cut you. I suggest you layout where you are installing the mat and cut to fit. From what I have read, you don't need to cover every inch in the vehicle, just spot install for a big difference. I chose to cover most surfaces to help keep sound out when we are sleeping in the van. We haven't finished putting the van yet, but we have driven it around and been very satisfied with this product.

Excellent sound deadening mats
Style: 80 mil 36 sqft, Style: 80 mil 36 sqft
Purchased these for a 2020 Lexus RX350 due to the hollow sound of the car doors when shutting. They sounded cheap. The mats are super sticky and I applied them when the doors were hot from sitting in the sun. They alubutyl sticks like crazy and the end result was perfect. Now I have solid sounding doors. Good quality product.

Good deal for the price
Style: 80 mil 18 SqFt
The product is good and contrary to some comments I read it was not a mess to install and went on very nicely. That said I placed on a 71 Baracudda and starting from a 71db I was able to drop that down to about 66 with two layers Kilmatt 80mil
