hi guys just wanted to pass on my comments just had my mk2 system fitted with 4inch tailpipe and all i can say is wow!!! first of thegarage said it was an excellent system to fit and also the quality was excellent!! the sound is excellent as well not too silly loud or anything i would say a little bit louder than a magnex i was crousing at 80 mph to mirror motorway speeds and it was not intrusive at all which is a bonus....the engine revs so much better now its untrue and even when thrashing home my mpg imporved...anyway highly recommended i managed to get mine for 100 delivered from ebay and it is mint condition think i saw one on there the other day as well starting at 99p!!! an also great poijnt is i cant here now the annoying renault quality build squeaks lol
