1. Finish and fit are awesome.
2. Took about 2 weeks.
3. Not sure exactly what you're asking. But it flows through the chambered mufflers.
4. It's not real loud inside the car if it's mostly stock. It gets much louder with a cam though

indy 93 and all who answered thank you on ? # 3 i mean are there any restrictions on this system kind of like the stock system where there is 1 pipe in and 2 that exit that kind of distrupt flow unlike the borla which has a bypass. i was told through a shop that all catbacks flow about the same which is true but the borla with its bypass flows slightly more . i can see why, there is nothing to distrupt flow. i was wondering if there is any restriction in the chambered muffler on this system kind of like what corsa claims that they have a non restrictive muffler. any more info will be greatly helpful and thank you all once again. chris.

No it's not straight through it flows from the I-pipe through dual outlets. I doubt other systems outflow it by much if at all. Even with better flow numbers another system wouldn't dyno much higher if at all.
