Flowmaster Announces New Axle-back
American Thunder® Classic System for 2005 - 2009 Ford Mustang

If you're performance fan Zach Tibbett, you want your black 2006 Ford Mustang GT to sound great and perform even better. While Zach's Mustang already had an enhanced exhaust system, he wanted a more aggressive system — after all not every Ford fan can afford a new $50,000 Shelby GT500.

After considerable research, Zach turned to Flowmaster and the new '05-'09 Ford Mustang American Thunder Classic System (Axle Back, PN 817460). Zach's comments: "I love the mufflers! The sound is awesome. It's loud, but not overbearing — at least to me. It really helped the sound of the Comp Cams Thumpr cam. Now the sound has a lot more body, its a lot throatier."

According to Lee Thompson of Flowmaster's R&D team, Flowmaster created this new axle back system featuring the 4-inch x 10.5-inch classic square case 40 series mufflers. The assembly includes the same 4-inch rolled edge stainless tips and 2.5-inch inlet pipe. The muffler assemblies are all 409 stainless with the exception of the tips that are 304 stainless. This is a true bolt-on system, and no cutting or welding is required for installation. Targeted at "enthusiast" customers, the mufflers provide an aggressive exterior sound level, and significant interior resonance similar to that of our 86-93 Mustang American Thunder systems.
