Utilizing factory cut points and mounting mechanics the Dinan exhaust system is a straightforward install with precision fitment just like you would expect straight from the manufacturer. Mounting and proper fitment is where the similarities to the factory exhaust end, however. Fabricated from brushed 100% T304 stainless steel, TIG welded and free of hydroformed pipes the upgraded system is a substantial improvement from its predecessor – both in terms of material/construction as well as in overall looks. When viewed from the rear the difference becomes unmistakable if it was not already apparent. Going from the plebeian stock dual slash cut 90mm (3.5″) tips to the massive Dinan straight cut 102mm (4″) ones leaves no doubt that something above and beyond is present. This is solidified by the Dinan logo laser engraved on the tips and the deep growl of the exhaust that is indisputably different than anything one would expect to hear from a base 4-cylinder turbo platform.
