Exhaust back pressure

Dessertrunner · #1 10-24-2007, 03:27 AM

Has any one mesured the exhaust back pressure before and after they changed it. I recently read a artical were they tested it before and after to see how good a job they did. I will try to find it again.

All should thank you Tony, well worth posting.

In the past there has been some absolutely stupid stuff posted in regard to tuned length by one in particular, together with lots of carry on about cat back stuff. All should note where the important tuned length starts and finishes, i.e., at the first point of expansion.

The after market thieves, knowing their market is restricted to the exhaust system only convertor onwards, whistle some outlandish tunes.

BY the way, a couple of times in different threads I have suggested that a few words from you, regarding your off road experiences, would be well received. Did you miss my posts?

Thanks again, Trevor.

Thank you for sharing. That is a must read for anyone contemplating exhaust modifications.

Autospeed has some nice articles. They influenced me into making a ram-air setup with one of my XT6s with the stock box (Negative Boost Article). I like their articles but some people do not.

Would be interesting to see what the stock SVX exhaust back pressure is measured at.
