Pro Circuit – 304 Factory Sound Silencer (KTM)

The Pro Circuit 304 Factory Sound Silencer is built for riders who want strong top-end power with a smoother, quieter tone. Designed for KTM two-strokes, the 304 uses a slightly longer body than the R-304 Shorty, giving you a broader powerband and reduced noise output — perfect for riders who want factory performance without drawing too much attention. It’s a race-quality silencer that looks clean, sounds refined, and keeps the power delivery crisp and responsive.

The 304 features a 6061 T6 brushed aluminum canister paired with a stainless steel inlet tube and end cap for lasting strength and a factory finish. Each silencer is TIG and MIG welded by hand in the USA, built to handle serious track and trail use. The double-walled mounting bracket keeps it solid under stress, while the allen-head screws make repacking simple so you can keep it running strong season after season.

Why We Like It:
It’s the perfect balance between power and refinement. You get that classic Pro Circuit hit, a clean tone, and a professional look that holds up to heavy use. It’s the silencer you can run anywhere — track, trails, or race weekend — and trust it’ll perform every time.

Why It’ll Work for You:
The longer canister design helps your KTM pull smoother through the mid and top end while keeping sound levels lower. It’s durable, easy to maintain, and built to deliver consistent performance without the extra noise. The brushed aluminum body and stainless end cap keep it looking sharp even after long rides and muddy days.

Variants / Options:
Fits most KTM two-stroke models. Compatible with stock or Pro Circuit pipes.

Excellent
Format: Paperback
As a second-year cardiology fellow, I used to get very confused with hemodynamics during my cath and CCU rotations. This book is a gem, it is clear and logically written, has great explanations of waves and great illustrations. The constrictive pericarditis, valvular disease, and FFR chapters are impressive with echocardiographic and physiologic correlations. I actually liked everything I read, like the nice differentiation between the pressure tracings of various chambers. Some of it requires multiple reads but it is worth it. I realized that I had missed a great deal of the basic understanding of pressure tracing configuration, wedge pressure, shunts. There are also over 50 cases in a test-answer format probably covering and reviewing most hemodynamic topics. It is like 2 books in 1.

Bought this book. Good content. However my copy is in black and white. There are references to colored arrows. I later learned that others have a colored copy.

AMAZING BOOK!!!!!
Format: Paperback
AMAZING BOOK!!!!!! WOW!!! everything you need to know about hemodynamics. This book explains the concepts with graphing, images. It also summarizes the key points. I wish I have read that book sooner. I could not believe it that in 1 book I found all the information I needed for the cardiology boards and my daily practice. Thank you o ugh Dr. Hanna for taking the time to write this book. Much Thanks!!!!

A welcome addition to training in hemodynamics
Format: Paperback
Purchased this book for my husband, the director of the Invasive Cardiovascular Technologist Program at a small college. He has been very pleased with the book, calling it a long-overdue addition to the field. It's very helpful in training technologists and others working in Cardiac Cath Labs to recognize hemodynamic waveforms and do calculations. It offers a lot of practice questions in addition to explanations.

Clear Concise
Format: Paperback
I like the way that this book is laid out. Rather than long drawn out droning chapters it is split into shorter more specific sections. The graphics are plenty big. The case examples and guided questions are useful in reinforcing the knowledge. A good resource for any new CVT or CVT student.
