I'm very happy. The truck is so quiet it is freaky. Under boost the Radix is clearly audible from the inside of the truck. It's a big time sleeper now at idle.

The magnaflow sounded great to me until I started pushing a lot of boost. I loved it on truck when it was still naturally aspirated. Once the big boost came, the interior resonance in the cab got crazy.

If anyone with a H2 is interested in my Magnaflow please pm me. I'll make you a killer deal on a 6000 mile catback. I must just be getting too old

 

Boost did not increase over the previous magnaflow levels. That tells me it is not any more restrictive.

 

Thanks to TByrne for the great deal from the Corsa group purchase.
