Miata NA/NB 1990-2005 · Exhaust & Mufflers

Stimulous checks hit and you guys BOUGHT EVERYTHING not nailed down!  We make most our RoadsterSport exhaust goodies here in the USA and those factories are ALREADY building our parts 7 days a week currently!  We are doing our best to update the page below as items go in and out of stock, notice items bottom of the page 'out of stock' or 'Prepay' have the estimated ETA in the subheadings when we have such an eta from the factory.   If you don't see the eta there, we really don't have it yet.  Please be patient with our team, we don't run the exhaust factories and we are doing our best to hurry up the process but these items are hand welded one by one and it just takes time and when sales volume suddenly spiked over 500% there is only so much the factories can do.

Note that EVERY brand of exhaust we offer will unmask the 'pops' of unburned fuel that are NORMAL in every exhaust system but normally below the hearing ability of the average consumer.  If you have no idea what I am talking about in the last sentence then please go on YOUTUBE and search "sports car exhaust pops" for a quick education.  Funny story about exhaust 'pops', when the good folks at BMW designed their MINI they wanted to make it feel less econobox and more sports car so they included a highflow exhaust from the factory so consumers could hear the fun pops from the first test drive.  Bottom line, if you want to hear less, buy one of our more conservative choices like our Racing Beat mufflers, and if you want to hear more of the fun pops then get one of our more aggressive choices.

Do NOT wrap headers. Wrapping headers VOIDS THE WARRANTY on every brand of header made.  The wrap holds moisture and also gathers petroleum emissions from under the hood like any oil leaking (meaning eventually you can have a fire).  Result includes fast degradation of that gorgeous polished stainless surface and the welds.   Wrapping headers is something that came from Drag Racing, but the Pro Drag Racers know it kills the header in exchange for another 1 or 2 hp scavenging benefit and they accept that it also means they get to rebuild the headers at the end of every race season.  Instead of wrapping headers consider our ceramic coated versions, or our header heat blankets (which don't trap moisture).
