MAD Fat Boy or Regular

I was wondering which one I should purchase and what the difference is. I plan on going with a single turbo kit later this year.

There’s really no difference. The backpressure is all inside the turbo housing, not in your downpipes (well, some, but irrelevant there). Pick what fits best, or do the ARM resonated ones if you don’t like rasp.

Single turbo kits should include a single downpipe in the kit.

If this purchase if for the stock turbos before you go single then I Agree, many of our customers love the tone from the fatboy downpipe and the piping diameter will be bonus.

The KLM has an option to add Downpipe but it’s for a pricier Downpipe. Would the Fat Boy work with any single turbo kit?

Don't believe so its single turbo with only one outlet instead of two. It wouldn't make much sense to put a Y pipe at the turbo just to connect to two downpipes when you could just connect direct to the midpipe.

Klm says it includes a downpipe 3.5 inch.

Kit Includes:

1.) Precision Turbo
2.) Wastegates 2x Turbosmart 45mm
3.) Blow off Valve Turbosmart GenV
4.) Coupler 3” (x3)
5.) Hose Clamps 3” (x3)
6.) Manifold True Twin Scroll T4 Divided Dual Wastegate
7.) 3.5″ Down Pipe
8.) Dump Tubes (X2)
