Borla muffler

[Bruce]

Does Borla just sell the muffler only for the GTS? Is there any advantage to purchasing the complete cat back system?

Pipe size?

Stock = 2-1/2"?

Cat-Back = 3"?

It'll be louder, drone, and will probably be .25sec slower as my GTS was when I installed the Borla catback. I'm not the first one to note the 3" system slowed the car down.

Interesting; the Borla actually slowed the car a bit. I'm mainly interested in a better exhaust sound (but not a loss in performance). Wonder if a cheap flowmaster muffler would help without suffering performance?

Here's the one that Belanger supplied when I did my side exhaust conversion.
