One of the best exhaust for the VA Platform

The Remark has an incredible deep sound and welds are top notch. Resonated midpipe is large and doesn’t hang too low, I’m lowered about 1.2” front and .8” rear. Mufflers themselves are lighter than stock so overall I believe it’s 5lbs lighter than stock, the fitment is one of the best fitting exhaust on the market especially with 4” quad tips... everything bolted right up without having to fight with the exhaust, tips aren’t low or too high for it to burn the plastic on your bumper like other 4” tip exhausts. For the price you cannot beat this exhaust in quality, would highly recommend this to anyone.
