what down pipe back exhaust (3inch bore) would you chouse to product the best power, and will be ok to use on a track.
i have a 3 inch decat down pipe and blitz nur spec r on at the mo, and am going to have probs on the track.
what do you recomend?
thanks

have seen a apexi exhaust valve, like a butterfly falve that can close off the pipe work abit, but i think it will be to restrictive,
sooo many different exhausts out there, but not sure what to look for, i love the nur spec, but it is just to loud for the track

We fit quite a few Milltek systems to classic and newage cars, they are true 3 inch systems, good for power. At SSO one of our customers ran his newage car with one, 12.34 1/4 mile and 89db on the static noise test.

H+S Headers, and turbo back Revolution on my 400 bhp classic, passed all noise tests at Castle coombe and they are pretty strict.
Other than that, as Pavlo says.
Full 3" decat Miltek.

Its quiet on cruise but fruity and deep when opened up.
Mine got a static 94db at Snetterton on Wednesday but i think I revved a little higher than the 2/3 max.

would a resonated centre section be enough, with out losing power, and if i get one that is 3" where it joins the down pipe, it will be a full 3" system, unlike how it is now, where the centre section joins the down pipe, it goes down to 2.50-2.75 from the nur spec centre section.
so bu fitting a resonated centre section, will it be quite enough, and will i lose any/much power?
thanks

i have got a 3" decat all ready, that mates onto a blitz nur spec r system.
i really like the sound the exhaust makes, but with the bung in, i think it is tooo restrictive.
so i was thinking of replacing the centre section, for one with a resonator in, but am unsure if it will make it quite enough (105db) and still keep the power up.

i am sure Paul would agree that noise doesnt necessarily mean power.
just be done with it, if you are keen to do more track days, and get a system that will produce the power and pass the noise tests.... Miltek is a little louder than Revolution and for a full decat system isnt expensive at all considering you can sell your Nur Spec on to anyone not on track and probably cover half of the costs.
All 3 inch system will give a nice sound on boost but with the larger tailpipe of the blitx the sound is too loud for most track officials unless you are lucky

You either want it to pass noise tests or you don't??
Keep the Nurspec back box then and have it modified to fit the rest of the revolution when not on track.
Track = full revolution
Road = Revolution downpipe+centre, nur spec back box.
