I have it on my car..recently I replaced the cat with a 108 mm 100 Cpsi made by them, so now I have the full exhaust line plus the 182 manifold, all 63mm diameter.
The car sounds great, and it's very strong at all rpm.
Kam racing is offering it at a good price and the system is available now.
the 14kg is from cat back, not just center section...? Got a link to the race cat or canyou pm a price to replace std 172 cup one.He has the mid silencer version. That weighs 14kg
