Yep and when you win the first thing they'll do is re administer the test correctly i bet. Now they won't know you have adjusted your exhaust so you can be smug and say i told you it was legal.

I wouldn't do this, I mean tell them you have made the exhaust quieter. The reason being after all this they WILL retest your car, the police are petty like that, when they test it at the lower rev limit and it passes, you have an even bigger point of saying "I told you so" it'll shut the smug bastards up.

you're right there, just don't understand why Norfolk wants to smell of cow poo rather than the perfumed aroma of Essex

This is good advise regardless of how loud your car is or is not, too many web fingered inbreds round there......

Interesting, will be following this as the GTO at 3/4 revs will shake your windows, unfortunately 3/4 revs 5250 and it makes max power at 6000rpm so falls into the 375 test. Now that is much MUCH quieter, but going back to the difference in testing methods ie drive by and static, i can without doubt say the GTO is much quieter under load....

This is how I see it: Car built for the Japanese market = JDM Car built for the Japanese market and modified with Japanese parts/brands = JDM Car built for the Japanese market and modified with non Japanese parts/brands = JDM but diluted somewhat. Car not built for Japanese market = Japanese car Car not built for Japanese market and modified with Japanese parts/brands = JDM styled Japanese car Car not built for Japanese market and modified with non Japanese parts/brands = modified Japanese car

What annoys me more is when people claim parts are JDM when they're just late spec/facelifts parts available across the globe. For a car to be JDM in my opinion, it should have been originally sold in Japan, as the JDM models all have a different (normally better) spec' compared to the Europeon/USDM equivalent. However to keep a "JDM" car JDM once imported it needs to be modified with Japanese parts. Too often I see nice cars fitted with cheap Ripspeed/ebay toot. If you want to modify it, use jap brands like HKS, TEIN, Kakimoto etc, only then will your car stay true to being JDM In my opinion.
