Agency Power has no limit for creativity and inspiration. We are constantly inspired and encouraged by customer feedback about our products. This STi owner took our Agency Power Stainless Steel Header (02-12) and made it his own. He also complimented his AP bellmouth Downpipe with our Agency Power Titanium Tip Catback Exhaust. This particular model exhaust for the 08-12 STi Hatchback can come with or without the muffler, and if you are looking for a significant power gain like this customer we have the entire turboback section all together.  Would you get the catback with or without the muffler? Let us know here or on Facebook, Twitter or Instagram @agency_power.
