This is the same question you had over on SIP where you said you didn't want to fit a snail system,right?
I think you can discount all down and forwards given what I've heard about them,Mike will be better qualified to give you an honest opinion though.
Which leaves us with a guess providing you're staying with the standard barrel position and not going reverse.The Polini Evo which looks the business but I don't know how they perform nor how durable they are.
I can't think of anything else on the market which may fit the bill,hopefully someone else can.

IMHO thats quite tall gearing so steer clear of revvy exotica.

i always go reverse barrell then fit a left hand zirri pipe looks nice on left hand side or if you fancy spending a bit i think b-race tuning would knock you one up

IIRC the 90 gearing is 3.00 and too tall for a 4 speed 'box.Maybe look at 2.56 to give you more options?

;D errr too many stellas deleted my last reply , but in short :-
revvy kit and no cylinder reworking and 2.86 or 3.00 gearing and zirri short 4th = simo D&F , zirri silent
revvy kit off the shelf 2.54 or 2.56 gearing and no short 4th = PM40. gruppo pillotti or Leo.
revvy kit with additional cylinder work, zirri short 4th and 2.34 gearing with a fucking huge reed block = zirri, sip evo, JL/RZ SIP curley.
This is just what myself and lads I know have tried out on different setups, some running reeds and some running rotary valve, with varying carb sizes and varying performance goals ranging from high speed touring to TnG racing round the streets.
I believe the PM40 is the best all round exhaust as it is capable of HP achievement on a myriad of setups (yes I said Myriad), but the Leo is a great value exhaust for the paltry amount of money it costs.
Most importantly though I am full of shit and once again on the Stella which tastes fucking great. Merry xmas to u all ;D
