Body T304 Stainless Steel","description":"\u003ch4\u003eShort Body 3 Inch Round Stainless Muffler for Tight Exhaust Packaging\u003c\/h4\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eR300-10\u003c\/strong\u003e is a 3 inch round weld on muffler with a 10 inch body, built from T304 stainless steel for performance exhaust fabrication where a shorter muffler body length is required. Vehicles with limited undercarriage space between axles, frame rails, or other hard points sometimes cannot accommodate a longer muffler body without routing the exhaust in a less than ideal path. The 10 inch body of this muffler provides sound attenuation in a more compact overall length, giving fabricators the flexibility to position the muffler in the optimal location without compromising adjacent pipe routing.\u003c\/p\u003e\n\n\u003cp\u003eThe 3 inch inlet and outlet of the \u003cstrong\u003eR300-10\u003c\/strong\u003e keep the full tube diameter through the muffler body for maximum flow, and T304 stainless construction ensures the assembly holds up to the corrosive and thermal demands of a performance exhaust system. For builders who need a quality weld on 3 inch muffler in the shortest body length available in the Kooks round muffler lineup, this muffler is the answer. It pairs directly with the R300-14 for builds where one side of a dual exhaust has more room than the other, or where a single muffler in a tight mid chassis location is the preferred configuration.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3 inch inlet and outlet for 3 inch exhaust system compatibility\u003c\/li\u003e\n  \u003cli\u003eCompact 10 inch body length for tight undercarriage packaging\u003c\/li\u003e\n  \u003cli\u003eRound body profile for standard fabrication integration\u003c\/li\u003e\n  \u003cli\u003eT304 stainless steel construction for durability and corrosion resistance\u003c\/li\u003e\n  \u003cli\u003eWeld on installation for a permanent, leak free connection\u003c\/li\u003e\n  \u003cli\u003eUniversal fitment for custom fabrication and replacement applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1 x 3 inch round weld on muffler with 10 inch body\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003ePart Number (MPN)\u003c\/td\u003e\n\u003ctd\u003eR300-10\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eContact us for UPC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInlet Diameter\u003c\/td\u003e\n\u003ctd\u003e3 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eOutlet Diameter\u003c\/td\u003e\n\u003ctd\u003e3 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBody Shape\u003c\/td\u003e\n\u003ctd\u003eRound\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eBody Length\u003c\/td\u003e\n\u003ctd\u003e10 inch\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003eT304 Stainless Steel\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eInstallation Type\u003c\/td\u003e\n\u003ctd\u003eWeld On\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eFitment\u003c\/td\u003e\n\u003ctd\u003eUniversal\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch4\u003eFrequently Asked Questions\u003c\/h4\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat pipe size does this muffler require?\u003c\/strong\u003e\u003cbr\u003e\nThis muffler has 3 inch inlet and outlet connections for weld in installation into 3 inch exhaust tubing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the advantage of the 10 inch body over a 14 inch body?\u003c\/strong\u003e\u003cbr\u003e\nThe 10 inch body is shorter, making this muffler easier to fit in exhaust systems where space between axles, frame components, or other hard points is limited. It is the compact option in the Kooks round 3 inch muffler lineup.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eIs this muffler louder than the R300-14?\u003c\/strong\u003e\u003cbr\u003e\nGenerally yes. The shorter 10 inch body has less internal volume, which means slightly less sound attenuation compared to the 14 inch body. This muffler will typically produce a more aggressive tone at similar system configurations.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eHow is this muffler installed?\u003c\/strong\u003e\u003cbr\u003e\nThis muffler is welded into the exhaust system at both the inlet and outlet. Both connections are welded to adjacent 3 inch exhaust tubing.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat material is this muffler made from?\u003c\/strong\u003e\u003cbr\u003e\nT304 stainless steel, providing corrosion resistance and long service life in a demanding exhaust environment.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eCan I use this muffler in a dual exhaust system?\u003c\/strong\u003e\u003cbr\u003e\nYes.
