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

Very comfortable Slippers. Great buy!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
I bought these to replace a pair of slippers that I have had for years that are very similar to the slippers I bought, but I had worn a hole in the leather on mine, so I had to find something new and similar. These slippers are worth the money they are very comfortable, and I am sure they will last for years. They are a little tight around the ankle cuff but they are still new and I am sure they will wear in a little more when I start wearing them more.

Great slippers but disappointing quality.
Size: 7.5-8.5 Women/6-7 Men, Color: Ash, Size: 7.5-8.5 Women/6-7 Men, Color: Ash
Extremely comfortable, attractive slippers but the stitching came loose on both leather trim areas almost immediately. I tried to sew/glue down the stitching (as seen in photo) but it kept unraveling. Disappointing as these slippers are great in every other way (though they do run a bit big...I wear a 9 but ended up with a 7.5-8.5 which fits with a bit of room to spare even with thick socks). I just hope they hold up after my latest attempt to stop the thread from pulling out any more as I do really love wearing them. Perhaps I just got a bum pair?

Quality and comfort
Size: 10.5-11.5 Women/9-10 Men, Color: Black
Comfortable and fit well. I got these to replace a very old pair that finally wore out! Warmth is medium (I wear puffer booties for when it's really cold). Quality on these is great!

Can't go wrong with Acorn for as long as they last!
Size: 12-13 Women/10.5-11.5 Men, Color: Charcoal
Acorn is just a great company all around. I had bought my husband these slippers over 20 years ago. They are still in great shape although the sole has worn in some places. But nothing's coming apart! However, I decided to replace them for him. His foot is 10.5 and they are a little hard to get on right away-of course, after over 20 years of having "worn in" the original pair, anything would feel tight. So I'm not holding this against them. They will relax with use. The only difference is that the original sole was black and these are tan. I think I would prefer the black, but since it's only being worn in the house, no big deal. My husband has really cold feet and these slippers never fail to warm his feet right up! He said they feel really soft to walk in and like the cushioning. They're not too heavy and fit him great! I have Acorn slippers myself that I've worn every single day in the house and outside to the mailbox too. They last.
