I can speak for the quality of Nino's uppipe firsthand. I bought one of his uppipes and installed it 2 weeks ago. Initially I was impressed with the power gains as per the butt dyno. Well this past weekend, a few of us headed over to Atlanta for the SoA and SoG tour. I won a chance to dyno my car for free and here are the results...
211 Wheel Hp and 208 Ft/lbs
Exedy Organic Clutch Kit and Ededy Lightweight Flywheel
Borla 2.5" single tip cat-back
K&N Filter in the stock airbox+silencer delete
Stock engine management
To get a feel for what these numbers mean, a stock wrx dynos 172 Wheel Hp on that particular dyno
Another WRX went on the dyno after mine
He put down just 215 Wheel Hp on more boost
I am 19 Hp shy of Prodrive's Stage 3 setup for considerably less money (prodrive stage 3 runs upwards of 19lbs of boost)
Just wanted to give you an opinion of the quality of your part Nino, since you asked about it when I called about the status of my order 2 weeks ago.
