Out Standing Product by Li'l Red Wagon, October 18, 2011

Ease of Use/Installation:
Overall Rating:

I purchased a set of Borla Headers 10 years ago for my 2.5RS they were very easy to install even in my driveway. The Sound is Outstanding as well as the entire Power Band if you have a NA Subaru and want more power this product is for you no dissapointments.

Ease of Use/Installation:
Overall Rating:

I recently put a pair on my 2003 Subaru Baja, the install takes 5 minutes... once you painstakingly undo the bolts on the old factory header. It sounds unreal almost like a harley at idle. It really improves the mid range torque without sacrificing any on the low end
