1/10 Inline Exhaust System (Side) Overview When it comes to security and performance, in-line exhaust systems are tough to beat. Now Dynamite has four new in-line exhaust systems that will fit a wide variety of cars and trucks. Each system features a flanged, spring seal coupling system that drastically reduces any chance of failure or breakage. Their pre-tuned system length keeps tuning constant throughout temperature changes. Installation is a snap, thanks to the included mounting hardware and preinstalled pressure tap. The 1/10 scale systems are available for either side or rear exhaust engines, and the 1/8 scale systems come in on- and off-road varieties. If you`re into nitro, you simply can`t pass these up. DYN6609 (1/10 In-Line Exhaust System for Side Exhaust Engines) is a great choice for HPI`s Nitro RS4, Losi`s XXX-NT, Associated`s RC10GT, or any other vehicle with a .12- to .15-size side exhaust engine.
