I'm interesting in getting some backpressure reading (actual numbers) from the exhaust from all you people modifying their stock exhaust(i.e. CTC Motorsport) to see what's the back pressure from the exhaust and where the back pressure develops and how much there? For example at cat inlet, cat outlet, downpipe inlet, downpipe outlet. I'm interested in getting new exhaust system, but would prefer the upgrade only the most restrictive section(s) for pure sense of better flow capacity rather than louder exhaust tones. Also I know backpressure is good for cat and emission, so I don't want to eliminate too much backpressure, so as to not be able to pass emission test. Thanks in advance.
