Finally got round to getting my cats and stillen y pipe fitted.
First of all many thanks to Tarmac for his fortitude when it got rough getting them from the states, well done and I am sure like others we do appreciate what you do for us .
So I took the ride over to RS at Leeds and had the berks and stillen fitted by "specky", boy do these guys kow what they are doing, even met a lad who came down from Scotland because like me he believes these are probably the best car engineers in the north (a bit like Carling). During the fit I was able to go under the ramps and helped with bits and bobs and also he answered all my inane queries about who what and where was everything. The job was done within 45mins, yes you were right Tarmac this combination went on like a dream, straightening up the exhaust first time into it correct position, didn't even have to cut off any bolts or nuts.
Paul the owner of RS took over next and undertook the remap using up-rev, as I had the licence from them it took under an hour and the cost was vastly below the original price,just the charge for dyno time per hour. I never expected any huge power increase and this was more about tailoring the new exhaust with the rest on the engine to get its best. However it took my 04 350z from 292 (previous remap) up to 300BHP and I was more than happy about this. On trial around the estate the sound does change from a stock scorpion to a pitch slightly higher and a unusual rasp sound that fits perfectly well with the car. My boy who has a BMW series 5 M3 had a run around with mine and came back saying how much better the torque was and given the choice he would go for the Z, there you go.
A big thumbs up for Paul and Specky at RS leeds lots of free advice and good day spent with them. Costs were £100 uprev and £50 for the exhaust well worth the money.
For those who want to know whats fitted to my car, and I know some out there are interested, a quite normal one, JWT popcharger, plenum spacer 5/16th, Scorpion box and middle pipe, Stillen Y pipe and Berks Hi-Flo cats, all combined with the Up-Rev re-map.
So just to finish, well worth the mods and yep driving around the last few day with a stupid grin probably looks out of place on a 59 year old
