Description

PRS presents an affordable, market-leading solution in the aftermarket downpipe space, designed to offer peak performance on stock and upgraded turbocharger applications for the VW MK7 & 7.5 Golf GTI.

Featuring a market-leading 4 inch top section, leading down to 3.5 inch end-to-end post flex-join for absolute maximum flow and 304 grade sheet-alloy blanketing, preventing drivetrain heat soak. 

Why is a 4 inch downpipe the perfect way to go?

4 inch downpipes have been tried and tested for years on the VW MK7 & 7.5 Golf platform, showing an increase in turbo response of up to 15%. This is not just limited to upgraded turbocharger applications either, these improvements can be experienced with the stock IS38 turbocharger as well. 

Why only 4 inches at the top and not throughout? 

After extensive testing via bench-flow simulation and dyno tuning we have discovered that the difference between 3.5 and 4 inches post flex-join is negligible at best, however, when comparing to traditional 3 inch post flex-join sections we saw a 30% + increase in flow, meaning that a 4 inch top section and an end-to-end 3.5 inch post flex-join section is the perfect combination. 

Heat shield (sheet-alloy blanketing) looks funny, cheap even, what's the point?

Most stock cars will see exhaust systems exceed temperatures over 500 degrees Celsius after an hours worth of urban driving, this is why we are now seeing manufacturers apply this race-derived technology to every day consumer cars as it is proven to contain heat emissions by up to 70% which if not contained will ultimately spread throughout the drivetrain and hamper performance. 

Now imagine how much hotter your modified car can get after a spirited drive or even a night at the strip/track? Trust us, if you want to prevent drivetrain heat soak and maintain peak performance, you'll want the heat shield.  

See below the benefits of heat shielding.

Some of the more "boring" "bells and whistles" you'd expect from a "top shelf" downpipe such as:
- Argon gas treatment
- SS304 grade steel material
- Tig welded joints
- Mandrel bends
- Oversized flex-join
- Heaty shielding 
- Cerakote finish (In areas without heat shield applied)
- Up to 40kw gains when ECU tuned
- OEM mounting positions
- Built-in reducer (For 3 and 2.75 inch exhaust systems)

INCLUDED:
- Downpipe
- Installation hardware

Get a longer launcher. This only throws 30 ft
Size: 1+3pack
Buy a longer launcher!!! I got what I paid for! A 12.2 inch launcher does not build up enough energy to throw it very far and it is tweaking my elbow. The dog is very disappointed since the ball only goes about 30 feet. I’ll keep it for small dog park use. The balls are hard and my 22 pound Cockapoo can’t get it to squeak.

These are dog tested and approved.
Size: 1-pack
The launcher works very well and will probably last forever unless your dog chews it up while bring it to you to get you to play, but the balls, well, they're not made for labs, that's for sure. That's the bad news. The good news is that worn out or abandon tennis balls fit the launcher just fine. Save your throwing arm. Do your dog(s) a favor. Buy this thing.

No angle for correct throwing
Size: 1-pack, Size: 1-pack
This item does not work. It is about ) inches tall. It’s tiny to bend over and pick up the ball. Has no angel for the ball to throw accurately. Ball goes downward. Would not recommend
