Guys, YesterdayI fitted my Tubi on my 348 Spider what a difference. My other sports exhaust sounds lounder on idle and has a more V8 sound. BUT, The TUBI sounds awesome when you open the car up. That is pure F1 noise. I catually think the 348 sounds better the 355. More hardcore some how. I got pulled by the Police last night for noise. Actually they thought I was racing when they saw me on the oposite side of the carriage way (Cops where travelling down the opposite carriage way). They actually turned around to get me because they could hear my exhaust. I was doing 30mph to 40mph in 60mph in Second to hear the noise...... They had a look under the engine bay. They asked if the car was different from the standard car, "No officer its catted can you see where the LAN sensors and thermal couplings are screwed into the spool pieces". "they are small cats arent they officer". The exhaust is standard, the car is LHD from Germany, but passed inspection at the DVLA in the UK. They just looked around the car. I actually revved it again at stand still so they could hear the exhaust. They actually said "keep to the Grand prix circuits and not on the public highway". They were going to noise test the car but could not get hold of a other response car that had the equipment for testing motor bikes. I got a warning and went slowly away.... Thanks officer. I am not sure if they were bullsh@tting about whole thing. Maybe a bit jealous.
