ITB Golf exhaust

[racer_tim]

Ralf, it's a RACE car. Expect some dis-comfort. I too run the exact same setup on my Limited Prep G (H now) Wabbit GTI. Header to a flex pipe, to a cherry bomb glass pack, to a 45 degree turn down in front of the axle. I did have a full system, over the axle through a flow master exiting out the stock location, but needed to knock off some weight, so I went with the simplest solution.

I don't wear ear plugs and also think the ringing in my ears and head ache after a session could also be adrenalin.

I ran without ear plugs once in a morning session and never want to do that again. I didn't regain my hearing until the next morning. I'm already collecting disability from the VA for slight hearing loss from 20 years in the Air Force. I've been around full throttle engine runs and lots of take offs and never experienced hearing loss like the 20 minute qualifying session without ear plugs in.

A body/brain that is not under stress from sound or heat will go faster over the time period of the race. If your head really likes the car shut off at the end of the race, chances are the exhaust is too load for you to make good racing decisions.
IMHO the pipe stopping under the middle of the car just makes the car a sounding chamber. The power increase might be nil over the turn out to the side,in front of the tire.
As an old guy that did not wear ear plugs sooner,and cant hear sxit now, put the pipe out the side and/or wear plugs.

I would not drive my car with any of the exhuast configurations I have used, without earplugs. Did so once by accident. It is bearable with the rear exit, but way more comfortable with the plugs.

I need to add "earplugs" to my shopping list.

Sorry, but I have to comment one more time in order to post a link in a new thread.

Seems one reads rules over again when building a new car. These two rules would seem to NOT allow the use of an under body, or turned down exhaust...I believe.

IT rules paragraph 1 g. "Exhaust shall exit behind the driver, and shall be directed away from the car body."

Glossary defines "Body - All parts of the car licked by the airstream and situated above the belly-pan/floor with the exception of the roll bar or cage." (Bold and underlined are mine.)

Since the "turn downed pipe" is below that point defined as the "body", I question its legality.

Plese show me how I can use the pipe below the car...I really need it. I have raced three cars with the pipe ending in a turn-down, and only now saw the words clearly.

Any thoughts?
