Looks to be quality built. Install was seamless with tsp titanium studs. Also installed with Prl front pipe. I cannot comment on performance or sound as the car is in storage for winter time. I only have one complaint the heat shield holes don’t line up perfectly and had to drill them out.
Should definitely flow better than stock. Easy install and comes with everything you need. I can’t comment on sound or performance as my car is put away for winter. I will add another review in the spring when the car comes out of storage.
I highly suggest this. It woke the car up especially with the tsp tune. I highly recommend doing the clutch upgrade as map 3 will slip the stock clutch. I’ve been tuned on the stock clutch for 10k miles and it just started to slip. I keep it in map 3 religiously, but drive like I want the car to last. Planned to do the clutch upgrade while the car was stored this winter. With that said I was really testing the stock clutch the last 4k miles
I used this cam plate when I installed arp headstands. Hopefully it gets rid of the leak I had with the oem one.
