Hi & welcome
I also came from a mk2 350 upgrade,& althou I loved it this mk3 is a brilliant car & handles so well.
Like you I’ve had the fpm upgrade with the scc ( sound suppression chamber )fitted. It has transformed the car so much from standard. I’m a commoner, nitrous blue, lol, keeping it as is now for warranty.
Don’t be put off by any crap you might read on this forum, am RS through & through & live the brand.
Many happy miles motoring ?
