This exhaust is completely sick. It literally gave life to my VB + when driving it close to redline it has a nice pop🔥

It sounds phenomenal and I am so pleased to hear that you guys did a phenomenal job on this F1 Valvetronic exhaust system. It's a chef's kiss to this product that you produced!!

Looks amazing and sounds amazing very easy to install just wish it came with the intermediate pipe for the price

Sounds really nice! Not as loud as they make it in the videos if you only get the catback. Needs the midpipe too for an additional $400. Personally, for the cost, I think this should be included. Great quality overall would recommend!

Awful hardware
Sound is decent and valves work nicely for now. Fitment is meh, partly from the ball joint things being annoying to make both sides even. BUT above all else the hardware and clamps are utter garbage. After less than 2 months on the road with no snow days all of the bolts are already pretty rusted and the bits holding the exhaust hangers on have broken off so I had to make up my own to keep it from dragging the ground
Hi Jack, please let me know which hardware you need. We will resend some Stainless Steel ones.

Nice product. Quick shipping. I purchased the first V3 and was happy with the price for something that was going to see abuse from the height of my WRX. After finally breaking it I ordered a V4. Mounting points lined up perfectly. I use plastic body rivets for ease of mounting and break away simplicity.

It was easy to install with the help of a friend. Love the look it gives and I can’t wait to get my front lip from them is next.

Easy install
The corner pieces have screws, which I was happy about, but I did have to partially remove my mud flaps to get to them. The center piece does not have screws and I just recently put some protectant spray on the black plastic and the tape wasn’t wanting to stick. So I put two screws in just in case. But happy with my purchase, looks so much better.
