OUR ONLINE CHECKOUT is CLOSED and we are NOT accepting any NEW orders at this time.

We are still fulfilling and shipping previously submitted and/or delayed order requests (as product availability allows) UNTIL NOVEMBER 15th 2022.

But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items).

Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. But we continue to endeavor to answer email inquiries as best we can. And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023.

We sincerely appreciate your patience, understanding during this period of restructuring and/or closing. And a huge thank you to all of you whose support and loyalty we have been the beneficiary of over the 23 years that we have worked diligently to support the information and parts needs of the aircooled VW community!

A-1 Performance Phat Boy Magnaflow MUFFLER, fits Small Flange Merged Headers (Old EMPI, Flat 4), With Flange Angled 10 Degrees Down

A-1 Performance Phat Boy Magnaflow MUFFLER, fits Small Flange Merged Headers (Old EMPI, Flat 4), With Flange Angled 10 Degrees Down
Photos show Stainless Steel Version on the builders awesome street car! This is just the muffler, the header is NOT included.
  
A-1 Performance Phat Boy Magnaflow MUFFLER, fits Small Flange Merged Headers (Old EMPI, Flat 4), With Flange Angled 10 Degrees Down. The finest muffler available for your VW, it's made to fit YOUR CAR (not one size fits none!). Please triple check what header you have, there are MANY different headers out there, they all vary slightly in their muffler flange orientation and location! These mufflers are designed to fit as high as possible for maximum ground clearance! These mufflers are NOT QUIET! If you want a "Quiet" muffler you need a "Turbo" muffler or Quiet Pack.

EMPI: If you have an EMPI Merged Header, you should know that they have changed their header design. The new design had the collector flange perpendicular with the ground (Straight up and down). The OLD EMPI design had the flange aiming toward the ground at a 10 degree angle. So the NEW Design fits the A-1-500M-2.5, and the OLD design fits this A-1-100M-2.5.

The A-1 "Sidewinder" is the best header and muffler around, but they are quite expensive, and it's possible you already HAVE a header, and just need a good muffler for it! Other guys actually prefer the "Old School" look that these Phat Boys have, you WANT people to see that muffler!

These A-1 Phat Boy mufflers are the ones you see in all the VW Magazines; the fast mega-horsepower California Street Sedans, and the Fastest Street VWs in the WORLD, it's like a quiet-pack on steroids! If you have a serious engine, you need to supply it with a MASSIVE amounts of exhaust flow! The Magnaflow Muffler outflows ALL the others, including "Turbo" (including Dynomaster), and "Buggy" mufflers. Non-straight thru design means you don't sound like a Motorcycle, Buggy, or Rice-Boy either!

This A-1 Performance muffler is the best balance of performance, looks, and ground clearance, of any VW Performance muffler available for your Merged Header. If you are looking at buying an A-1 product, it's obvious you value quality and want THE BEST!

Every A-1 exhaust product is hand made to order by a master exhaust system craftsman to the custom specs you submit for YOUR car!

A-1 Mufflers give top notch dyno-proven performance, and their maximum ground clearance is icing on the cake! These are not the Chinese made "One Size Fits None" mufflers made by the thousands in a Chinese Prison Camp that won't even bolt up to your header! If those DO bolt up, it usually sits Catty-Whompus or hits the ground! We've seen some "Horror Show" examples of this, and that's why when asked we recommend the A-1 Phat Boy!

A-1's headers are hand-built with Heavy Duty 16 gauge steel tubing, not that paper thin junk! Are you sick of flanges that are warped out of the box, or that bend during normal exhaust tightening? End THAT garbage once and for all with these Double Thick Tru Flat 3/8" collector flanges that are so straight you don't even need gaskets if you don't want to use them!

Vehicle Application


Choose Exhaust Finish / Coating



Ceramic Coating is a life EXTENDER, not a lifetime coating. In other words, you should expect the coating to make the pipes last longer than normal but don't expect the coating to be shiny or to last forever. Normal lifespan varies according to where you live and if you drive the car in the winter in the salt zones. Salt zone, daily driver summer and winter the systems should last about 4 to 5 years normally.
