FlowFX Muffler - 3.50 Center In/3.50 Center Out - Moderate Sound - Stainless Steel; Flowmaster's FlowFX series mufflers deliver a moderate performance tone for the enthusiast looking for an exhaust note that is different from the chambered muffler sound. The interior features a large 3.50 in. straight-through stainless steel perforated core, surrounded with high-temperature sound absorption materials delivering a deep traditional mellow tone. The internal flow design is reversible, so the muffler can be installed in either direction to best suit the vehicle application and offsets needed. Features include fully MIG-welded bright 409 stainless steel construction with the FlowFX logo embossed on both sides of the case.

very well made. I installed this on a 2010 silverado with a 6.2l that has LT headers. It was so loud before with a black widow muffler or a MBRP or flowmaster 40 series. This quiets it down to almost factory loudness at part throttle and normal driving. but when you get on it of course she screams bald eagles. Its a straight thru style muffer so no restrictions. I took a gamble with this and I beleive it was the right choice for my setup.
