Here at Sweet-Thunder we've made the decision to enter the bolt on exhaust system for enthusiasts looking for performance, sound, and budget requirements. Our first project now complete is the 2005/6 Pontiac GTO. Our system utilizes 2-1/2" 14ga aluminized tubing throughout the system. The integrated x-pipe / chambered muffler specifically designed for the application allows for a cleaner tight fit without sacrificing flow or sound (additional configurations listed below). Our system rides 1" higher at the front of the differential in comparison to the header pipes. We designed a single piece laser cut flange identical to the GM flange to maintain the strength of the front seal system. Hanger bars are made from 1/2" solid bright zinc plated steel. Furnished clamps are top quality American made. Exhaust tips are optional with the system to provide greater pricing flexibility, should you choose our tips they are made from 300 series polished stainless formed to fit the factory opening. Crossover options are: X-pipe H-Pipe No Crossover true duals As alway we choose material of the highest quality made in the USA or Canada.
