Our stock exhaust line is meant to take the place of a worn out factory exhaust. A stock exhaust is meant to be quiet, just like the exhaust that came on vehicles straight from the factory, without the high prices of a factory exhaust! Our stock exhaust is made of high quality aluminized steel and can be custom bent, or pre bent depending on application. We can also perform money saving repairs such as stock flex pipe and resonator repair! Here at Eco muffler we pride ourselves on our ability to replace just flex pipes and save the rest of these very expensive units, saving our customers hundreds of dollars.Our performance exhaust line is for people trying to add a little sound, and performance to their exhaust. We stock many different brands of performance exhaust, and can also make our own performance systems in house!
