Mazdaspeed3 Gen1 Stainless Steel 3" Cat-Back Exhaust by Cobb

The COBB 3" SS Catback Exhaust was engineered specifically to match the performance needs of the 2007-2009 MAZDASPEED3. The attention to detail that goes into the fabrication of this catback makes it a shame to hide it underneath the car. Manufactured using mandrel-bent T304 stainless steel with a custom resonator and high-flow muffler for optimal performance and reliability. Its factory-like fit, attractive finish and subtle yet deep exhaust note put it safely 11 dB below the SAE J1169 limit.

The COBB Tuning Gen1 MAZDASPEED3 Cat-Back is constructed purely from 304 Stainless Steel. The system starts with a stock donut-style flange that mounts to the OEM downpipe or any stock-replacement downpipe, such as the COBB Tuning 3" Downpipe.

Next up is a polished resonator section with attractive rolled end-cap, followed by a polished low-restriction straight-through muffler section, also with this attractive rolled end-caps. A thick stainless-steel 2-bolt flange connects to the final section of the exhaust that ends in a tasteful, slash-cut 3.5" double wall tip featuring an etched COBB logo.

poli glow shine
its works great .when applying more coats the shinier it gets i used on several old boats because the florida sun bakes the jell coat right off and no wax made can withstand salty seas , so why not ,, when you apply use the mit and don't gob it on .. nice and easy and recoat in five minutes when you get to about five coats you will be amazed.looks like new .. just a tip also after about a year or so and you want to re apply,, go to your local hardware store and get a gallon of high strength or non diluted floor stripper and put in spray bottle and use to remove old poli-glow also great for cleaning stubborn stains [ i use full strength ] just spray on and brush with a scrub brush and rinse ..and let dry and re apply ,, its also works on car faded bumpers ,, also never use harsh cleaners it will cause streaking the best thing i have found for cleaning the boat after poli glow was put on is car wash from auto store with wax or not it seems not to hurt the shine . it reminds me of mop an glow,,.

Poli Glow used on bottom portion of the picture
Just put it on 21 foot RV, was impressed with the shine. Key is to make sure the applicator is moist. I periodically dampen with water. Realizing it wasn't going to revive the stickers. Question is How long it will last? What will it look like after it rains? Pictures attached, bottom portion was done with poli glow on June 7,2026 and I have just under a half of bottle left. Maybe I will update once it rains or how long the shine last.
