The performance with the Borla exhaust was excellent. Nice sound and beautiful note heard at mid throttle. Borla tuned this exhaust for the corolla (check the Borla site)
Borla Exhaust System and new K&N air intake system
I do not have my 2011 Corolla S anymore.
The "Cat Back" Borla exhaust system is in excellent shape and the K&N air intake system is Brand New in the box!!
I have a brand new K&N filter kit, part # 69-8757TTK and a Borla exhaust system with less than 3,000 miles on it.
These fit all Corolla's from 2009 to 2013
I am selling both for $300
Price is firm as you can check what the K&N goes for.
Please contact me if interested.
