Why is our Exhaust so SMALL!
Man I almost forgot with the hesitation issue. But when we were installing my HFC's I noticed that I had two Honda Civic's exhaust pipes on my car .. What in the hech are these two straws doing on my car???
This is probally why me exhaust tips sound like there are gong to rattle of when my wife drives away in the moring..

Don't you think it's rather impressive that the two pencil's create that much power?

I accully do think that Nissan did a GREAT job making power with those toothpicks bowdown: by why not use something a little bigger.

Larger diameter pipe just weighs more....HAHA
Large diameter pipe doesn't make the car go faster, 2 1/2" pipe is large enough
up to somewhere around 400 RWHP. Almost every exhaust system that
company's like Magnaflow sells doesn't exceed that 2 1/2" figure! Unless you
have a Twin Turbo motor putting out major HP is there any need to move up
to a 3" system. Our cars will lose HP if you installed headers, test pipes and
a lager diameter system!

I know that but there is now way our exhauts is 2-1/2. 2 if its lucky. I was not expecting 3 inch dual exhaust like I had on my Monte( 650hp) but Civic exhaust just looks funny. We lose power from headers, Test pipes. That I don't agree with. I have HFC's and the car is pulling harder. Power still equals how fast the exhaust gas can leave the engine, to allow the pistons to move faster. I do agree that to large you will lose power..

My STi had one 3" pipe and smoothly pushed the 300HP & 300ft*lbs...
The G has 2 2.5" pipes. So total cross sectional for the G is about 10sq in., and the STi was about 7sq. in. Looks like the G has plenty of volume to flow the power, I trust the designers on most of thier set-up. Only thing I scratch my head on is the "Y" design into the one 2.5" pipe (cross sectional area here is about 5sq. in). To "solve" this I was thinking of trying the "H" I have seen on here a bit. Only posts showed butt dyno results. If anyone has more on NVH loss and performance gain please PM me (I dont want to hijack the post).
