PURCHASE DISCLAIMER: TR3 Performance does not condone the use of emission defeat devices for any vehicles used on public streets or roadways. TR3 Performance will not tamper, remove, disable, or bypass emissions equipment on a motor vehicle in accordance with 40 CFR Section 86.1854.12(a)(3), Clean Air Act 40 CFR 1068.101(b). This includes software, known as tunes, that reprogram a motor vehicles electronic control module to alter engine performance and enable the removal of filters, catalysts, and other critical emissions controls.

Fabspeed's Supercup Turboback Exhaust System for the 718 Boxster/Cayman is the ultimate solution for very aggressive sound and performance, with 3"/ 76mm mandrel-bent tubing to reduce turbo lag and immediately remove 36lbs / 16.4kg of weight from all Cayman/Boxster 718 cars while offering an invigorating increase in turbo sound and boxer engine rumble. Increased throttle response and track-worthy sound ensures you feel Fabspeed's difference.

Fabspeed highly Recommends an ECU Tune for proper vehicle operation and to eliminate any possible engine or hesitation issues. 

SOUND:

With Sport mode activated burbles and backfires erupt in abundance on overrun, and downshifts summon a bark that will make all eyes and ears around focus on you. The factory exhaust mutes the turbochargers, the free-flowing Supercup reveals their presence with a very pleasing increase in spooling sounds, adding more character to your driving experience. The boxer engine rumble is enhanced and refined in a distinct Porsche tone. This system is aggressive and maximizes power while also removing unnecessary weight from the LEFT side of the car. 

POWER:

The addition of Fabspeed's Supercup Turboback Exhaust System with Sport Cat added 10 whp and 13 ft-lbs at 4000 rpm as tested on our Dynojet. Expect more power and response with our Catbypass option. The Supercup Turboback is a very free flowing system and full potential will be realized with a tune. Fabspeed looks forward to extracting even more power with our hardware in conjunction with a Fabspeed ECU Tune at a later date as soon as possible.

    Way too small with very little stretch.
    I ordered a size 4X to make sure they were loose enough. The ones I received are like a size 8 very small.

    If you haven't switched to boxer briefs, you're missing out :)
    Size: 11 Plus, Color: Microfiber - Colors May Vary
    I figured I ought to provide a review, something I'm not prone to doing even though I often/always bank my purchases on item reviews, since I just bought me a second set of these underwear because they're just that good! I bought my 1st set of these 2 months ago because I was on the hunt for some new comfortable underwear and omfort was my main criteria. Wasn't aware that I was dealing with some health issues that was causing a fair bit of internal inflammation, just knew that I had had enough of basically everything I had at the time because they were old, ratty looking and even my all-time favorites had begun feeling too... something... not exactly too tight, yet they just weren't very comfortable anymore either and I didn't need that kind of extra stress in my life. But. I'm a barely-makin-it domestic violence survivor. Sure, I'm super proud to have gotten as far as I have in this world (considering that post-separation psychological terrorism and torture continue to thus day, 5 years after I broke free) but, by rights and family-rearing, I should be living in a whole different world right now... which is my way of saying that money is extra, EXTRA tight in my house...and yet, I still have "caviar tastes", ifykwim. Lol. And, frankly, neither I nor anyone else should have to scrimp on comfortable, classy-feeling, fashionable clothing no matter how small our clothing budget may be. I was spurred to check out boxer briefs for women after reading about a few different women's favorite brands in the comments on soneones IG post (that must have been in regards to underwear, but heck if I can remember the details). So, off I went to scout around on Amazon to see what this "boxer briefs" business was about... desperately hoping that the term was not just a rebranding of those "hipsters" things. I am 46yo, 5'10" (potentially closer to 5'11"... not something I care enough about to know for certain, lol) and, clothing size-wise, my whole adult life I have consistently been a 16-18/18-20, top to bottom, with a shape that seems some what apple-ish at the moment but has, in general, always been more hourglass than apple. Also it seems as if I might have rather freakishly high hips, lol... not really, but for reference, when it comes to pants or jeans what generally passes as "tall", usually a 33"-34" inseem, fit like ankle or cigar length pants on me. But evidently I don't just have long legs, no, this momma's body seems to also have one heck of a long, tall pelvis which I did finally measure to figure out for sure but, prior to that, I could tell based on the way that low cut underwear like bikini & hipsters, and any form of low rise pants, barely make it north of my low lying c-section scar location which, for those who can't relate, is basically at the top of my hooha or just at the point where my belly and my hooha meet. And because that point on my body is not even remotely close to my "hip" area such items basically fall right off my body unless they're super stretchy and I deliberately hike them up to my hip area which I put up with in my 20s and 30s, for the sake of fashion I suppose, but which was and is quite ungodly uncomfortable, and... basically... I am so over with "uncomfortable" anything (men included, lol.) In both cases I bought size 11, though, if I'm being honest, I am certain that a 10 would have fit well, too. And who knows, a 10 might have been just as comfortable or even more comfortable than the 11... but, I didn't take bother taking the chance to find out when I ordered my second set because the first set (size 11) made me so unbelievably happy that they literally changed my views about underwear for life. This whole "pants come off after work" thing or the memes about people working from home (due to covid restrictions) and not wearing pants never jived with me prior to having these boxer briefs, but now... omg... these things are super inexpensive and somehow still suit my somewhat "caviar taste" perfectly (have a good handfeel and are just so unbelievably super comfortable), PLUS... they're opaque and they basically fit (and look) like I'm wearing a loungy pair of bike shorts, so... yeah, I've spent some time over the last 2 months actually chillin in my house in my freaking underwear!!!! Life. Changing. :D
