Guys I need help.... I have been invited on a track day next week and the decibel level is 98db which is obviously quite low :( Does anyone know what the db readings are for the GT-R with a Miltek Y-Pipe fitted for a stationary test but also whilst giving it large round the track? Any help would be much appreciated.

The Milltek wont do much more than 90db, stock is 88db, the full GTC Titan only does 98db and thats far less restrictive.

I think i read somewhere it was 92db the Milltek.

I wouldnt worry about removing it.

The Milltek should be fine for trackdays,static readings on the GTR are very low,driven should be fine too....:thumbsup:

Goodwood?

Think you'll be ok with the y-pipe, just don't have any overrun near the sensors :chuckle:

Way out - mine has been tested at two different tracks with two different meters and was well over 103 at 3/4 throttle.

I think the OP is talking about Goodwood my home track and they are very very strict on noise levels.

Have to agree with kp that Robsm's figures are way out.

I was tested at Oulton park in November. Standard car with no mods other than a Miltek Y-Pipe and i hit 105db. (the allowed limit!)

Tested at Bedford yesterday measured 98.1 db static at 4500 rpm, Miltek y pipe with oem exhaust, if that helps. Drive by was also fine, said they would give me a warning if getting close to limit but never heard from them.

That is very odd as mine was way over that with the same setup - How old is your Y Pipe and do you know if they have changed the design at all.

Had it fitted two weeks ago at Middlehursts, not aware that the pipe has changed at all, was yours at 4500rpm or more?
