apexi n1 evo [no cat]

or deep tone ,

hks superdragger [no cat] and remove center silencer for fabricated straight through pipe [30cm approx pipe]

you'll be heard for miles at 6-8000rpm ;)

or custom made 4 inch straight through

or if you need it louder still,

custom made side exit 4 inch straight through with exit 6x4 ( ) shape [like a megaphone] lol :D

above is for single turbo, if you use twins fabricate the down-y-pipe to be a fair bit bigger, dont know nissan y-pipe diameter????


or use 2 side exits straight from the twins about 2.5-3'' inch each, no y-pipe

i have a kakimoto twin mega n1 dual.


loud s.o.b. i have run silverstone though with no problem but i have a feeling it is still over 105db :S

mental note at any point in the rev range. can be a bit loud sometimes but the on boost noise is just purely so insane i would never get rid of it!

is two complete pipes turbo back, decatted and a single muffler each pipe.

just to add to the replys above, you can also get a dual hks superdragger exhuast - one full exhaust per turbo.........., but running the small twin turbos,
a TRUST wider y-pipe and one superdragger exhaust will be plenty [no cat, no centre silencer]

that way u save weight and save money on the 2 full exhausts;)

blocking off the std recirc valves gets a nice chatter and chirp but nothing loud like external wastegates or d/v's

But tbh i dont want psssssssht everytime i come off the throttle, im happy with what mine sounds like.

here is a youtube vid of my 0-60 doesnt give you an idea of normal driving noise but gives you a gist of noise levels YouTube - TRAX 09 - 0-60 [CHRIS GARNER - R33 SKYLINE GTR]

you want super loud? ill sell you mine :p
Trust Type RD, has For Race Use Only stamped on it, is 4 inches front to back, no silencers or resonators anywhere :p just the back box, my car was being pushed for 1000bhp so it was necessary.
Tested it and it sang to the tune of 106Db at 4000rpm and that is with a silencer bung in the back and the middle pipe swapped for a cat pipe as it was going for an MOT at the time.
If you want loud, you should go for one of these, people could hear me coming from a very long way away.
Not completely sure, but im pretty sure it had to be custom made my Trust, cost upwards of £1200CYP at the time, oh and its stainless steel btw
