Kooks "Afterburner" Stainless Axleback - 2005-2006 Pontiac GTO

Fastlane is excited to announce these new "afterburner" axlebacks from Kooks Custom Headers. This new system features Kooks new straight through Afterburner mufflers, which produce an awesome deep tone with volume, but almost no rasp. These systems feature new polished 4" double wall, round stainless steel tips that fill the 05-06 GTO Bumper opening perfectly! These systems are 3" all the way through and features a special 3" flange that bolts right up to the GTO's 2.5" factory exhaust! This axleback is the perfect balance of refined sound, and world class quality at half the price of most GTO catbacks!

These systems are tig welded using the same aircraft grade, CNC mandrel bent 304 stainless steel that Kooks uses in their world famous headers. All systems come with grade 8 bolts, new gaskets, and instructions. Last but not least, all they come with Kooks warranty and support behind them!
