Well Made But Too Loud!
The exhaust is very well made - bolted right on within about an hour. However, this exhaust is not a touring exhaust. It's a racing exhaust. Much too loud for normal street use and lots of interior drone, especially at about 2,500 RPM (which is 60mph to 65mph). Took it to the track and loved it, but wakes up the entire neighborhood in the morning. It takes away from the sweet sounding induction of the 6 cylinder. Going to put back on the stock exhaust. It did improve fuel economy.
Installed on a 2007 Cayman 2.7, by a local independednt Porsche shop. Although they had done nmay other catbacks, they said it was their first Borla, and they remarked favorably on superior quality of the construction, welds, design, and ease of installation. On the car, it has bumped up throttle respnse, and has changed the exhaust note to a more exotic tone. And, the price was right.
