I have all 3 exhuast at home and currently the mugen full cat back is on my car rite now. Which exhuast do you think would flow the best? I had to skunk on there before but it was way too loud and i got pulled over a few times for it. Then i decided to get the mugen but the mid pipe looks very restrictive. Then I came across the comptech one which seems like the one that i am going to go with. What do you guys think?

 

dyno test all three - then post the results

 

I wish i could but i dont have the time or the money to do so.

 

if your going to street the car then mugen all the way love the tone of that exhaust. If your going to max power (maybe like 2-3 more hp at most) then something like skunk is good but it will sound like *** and be VERY loud. I'd keep the mugen all day long

 

The mugens are probably the quitest thing you can find that suck the least amount of power from the car but if power is what you want then something like a BC would be good but as you figured out too noisy.

I have had friend flow 210 over here with mugen exhaust system on a B20.
