The answer is that things don't work that way, friends… Here are a few basic steps before buying a sport muffler online without the risk of making a mistake: Definitely check the car from underneath on a lift or pit, paying attention to what shape muffler you will need – oval or round; Pay attention to the arrangement of the inlets and outlets of the original exhaust system – number and arrangement. Usually, the options are as follows: One inlet and one outlet; Two inlets and one outlet; One inlet and two outlets; One inlet and one offset outlet; T-shaped muffler; And others. Be sure to measure the diameter of the original exhaust system with calipers. Standard sizes in the automotive industry are usually φ51 / φ63 / φ76 mm, but there are exceptions and variations. Last but not least – be sure to measure the available space in your car. Length, width, and height that you can fit. If you follow these four steps, you can easily choose your new sport muffler and save yourself headaches, unnecessary money for double labor at the mechanic, and courier costs. In our store, sport mufflers are categorized by size, brand, and purpose, which will make your decision easier.

A sports muffler is one that offers the least possible resistance to exhaust gases. In motorsport and tuning, sports mufflers do an excellent job of improving gas flow in the exhaust system. In factory car exhaust systems, exhaust gases encounter restrictions and silencers that create an obstruction and impede flow. The design of sports mufflers allows gases to exit the combustion chamber as quickly as possible, resulting in increased power and torque. The mufflers from RM Motors have several layers of sound-absorbing materials - the perforated tube is wrapped with a stainless steel mesh that separates the stainless steel wool from the gas flow chamber (in cheaper silencers, you often see "wires" in the passage). Another layer is refractory steel wool, which further reduces the energy of the gases, thus eliminating the metallic hum known from cheap silencers. An outer stainless steel casing, made of acid-resistant 304 steel, protects the silencer from external damage and rust. The type of exhaust also influences the sound - we offer both oval and round solutions. RM Motors sports mufflers are hand-welded in an argon chamber, which guarantees an excellent design - extremely precise and colorful welds give a distinctive look to our products. RM Motors sports mufflers are a professional product at an affordable price, available in round and oval versions with different inlet and outlet sizes, as well as different silencer box sizes. Construction of sports mufflers. RM Motors silencers are among the most modern designs available on the market. Made of 100% 304 grade stainless steel, they guarantee an incredible look and durability, features that every car enthusiast will appreciate. The internal construction is comparable to leaders in the global industry, consisting of several layers: a perforated stainless steel tube, a stainless steel mesh to prevent burning of the muffler material and stainless wool from entering the gas flow area of the silencer. RM Motors silencers are finished with a polish, ensuring excellent gas passage, maintaining the distinctive sound of the powertrain. It is worth mentioning that these are solutions that will withstand even the harshest operating conditions. In addition, they are characterized by high performance and durability. The muffler can be used as both a mid and a rear muffler. The distance between the outlets is designed to allow parallel use of 2 flanges or a V-band, which makes it much easier to use as a mid muffler. Leaving both outlets in stainless steel or equipping them with additional tips makes it an excellent choice for the rear part of the system as well. RM Motors Sports Exhaust Systems RM Motors is a manufacturer of sports exhaust systems; its range includes universal and specialized solutions. Universal options are characterized by a wide range of choices, with box sizes ranging from 250 to 550 mm, and inlet and outlet diameters from 50 mm to 89 mm.
