Mighty Car Mods show you a variety of sound comparisons of the full 3 inch exhuast, with Varex Muffler by X-Force on their S15. There is a complete install which is part of Season 02 Episode 04 which can be found here:
Also something to note around Mighty Car Mods: we are normal guys and are not trained mechanics. We like to make interesting car mods and show you how we’ve gone about it, but we can’t promise that anything we show you will work for your particular car, or that you won’t harm yourself, someone else, your car or your warranty doing it. Please be safe, be responsible and unless you know what you’re doing, do not fool around with very serious machinery just because you’ve seen us make it look so easy. Talk to a qualified mechanic if you are in any doubt.
