XForce 4" to 3" Turbo Downpipe & High-Flow Cat Kit - Audi RS3 8V & TT RS FV - ESRS317KITB

Unlock the full potential of your 2.5L TFSI engine with the XForce Turbo Downpipe kit for the Audi RS3 (8V) and TT RS (FV). This premium upgrade is designed to maximize exhaust flow by replacing the highly restrictive factory component. Crafted from high-quality 304 stainless steel, the system features a massive 4" inlet that transitions smoothly into 3" mandrel-bent tubing. By deleting the secondary catalytic converters and utilizing a 200-cell high-flow metallic race cat, this kit significantly reduces backpressure, resulting in improved throttle response, increased horsepower, and a much more aggressive, visceral exhaust note.

  • Secondary Cat Delete: Replaces restrictive secondary cats with a tuning pipe to ensure unrestricted power delivery.
  • Direct Replacement: Designed as a bolt-on replacement for the factory downpipe; no cutting or welding is required for installation.

Budget Seiko Prospex this is not
Color: Black/Orange
Bought this as a cheap work watch, but I guess all the budget went into the solar technology. No date adjust feature, gotta crank the crown over and over to adjust the date. (Also no screw-down crown, but that's expected at this price) Fake diver bezel. Lol why? Cringe as heck. Should of just put a compass bezel on there instead tbh. Cheap plastic crystal, scratches and mars just by looking at it. Okay NATO strap. Falls apart quickly, but it's easily replaceable with a better quality one. Decent lume on the hands, but none on the hour markers even though it looks like there is. Looks cool.

Simplicity
Color: Black/Orange
This watch was received exactly as advertised. First off the watch is economical compared to other watches that advertise the same details. I will say that I have gone through numerous Luminox watches only to be disappointed. This watch fits the bill. It does have solar cells which mean it needs to be exposed to light to keep running, not a problem. Three minutes under my surefire light I am golden. The bezel doesn't rotate actually no big deal for me. I have always required that the bezel moves not anymore after having a bezel that rotates I use it next to never. Here's why, the more I rotate the bezel the more the numbers wear off. The strap on the watch with the catches for the strap are perfect. They actually hold the watch strap in place in lieu of like other big name brands that just flop and slide. As far as everyday use goes this watch is my go to. To be honest I have purchased three. This is the only watch I will wear moving forward, yeah the glass my scratch but even the big names like the Luminox I spoke of earlier scratches too.

Companion to the best map markers ever!
These are a must for minor corrections when using their pens!

Didn’t know what to expect and was pleasantly surprised
Purchased to go along with the staedtler color markers. Mostly writing on laminate and loksaks. Works well and allows you to easily wipe off any permanent marker. Curious as to how long it’ll last. Keep a small cloth to wipe nib clean after use.
