Well worth the wait for these GESI Hi Flow catted Downpipes. Thank You APEXBuilt, INC (Graham Conron)
I didn't believe that these downpipes would WoW! me with any noticeable significant throttle response once installed.
But, But it was mind blowing. Driving the Car home form the installer was like driving a totally different car.
The Throttle response was so aggressive. I wasn't expecting this at all.
I was blown away. The Car accelerates so much faster than stock. yellow on the Tac comes so quick and it feels like i have gained more than 50HP. Maybe. No regrets. If you can afford these. Get them. You wont't regret it. Can't wait for my next drive.

Very high quality product here. My installer (who's installed every downpipe there is on this platform) commented on how well it was built. Fitment is good and the sound and performance is awesome!
