im amazed with the results of just a cone air filter, dumping like theres a dump valve, took a lot of work to get the old air filter/box out and the piping, but we got there i the end, best £16.95 i've ever spent
It hardly sounds like a dump valve really but it is close enough! Haha! Not loud enough for me I'm going to go and see Forge to see if they will look into developing one for the bravo and grande punto t-jets because they dont make one!!!!
If yours is as ;pud as mine I don't think you'd want it any louder, these are only 1.4 engines anyway... overstating them would just be lame. The sound you get from that cone filter, well mine is amazing!
