The only exhaust I have found to flow well and be quiet enough to no annoy and attract attention is the revolution 3inch exhaust.
But I find it great for a month or so and then two quiet so I swap about

I agree about the flow and your analogy to a hose, but was thinking more about the heat and density being far greater at the header end compared to the tailpipe end. The tailpipe bung when fitted to luckys probabley has a centre bore of around 2.5 Inches in a 5 inch tailpipe, which is no smaller then the rest of the system. He also still has both cats in place which are going to be far far more restrictive then a 2.5 Inch straight through bung.

It's a fairly standard car so not maxing the extraction capabilies of the exhaust system.

Lucky, best thing would pop over and i'll strap all my bits on and double check it. if I can detect det or any major change you can then decide whether to live with the noise or go see Simon for a tweak.
