Which 3 inch exhaust?
Looking to upgrade from a 2.5 inch to 3 inch. Want something that is not to noisy but does show off the rumble/burble. Also want a straigh exit pipe at the rear (ie, not angled). What are the good options to go for these days?

For value for money, I'd go for this Cobra item - £175 for back box with 3" inlet...

IMPREZA REAR BOX (ALL MODELS)
FLAMEBURNT:
STANDARD (+£0.00)
FLAMEBURNT (+£7.50)
PIPEWORK :
STANDARD (+£0.00)
2.5 (+£0.00)
3 (+£10.00)
SLASHCUT TAILPIPE:
STANDARD (+£0.00)
SLASHCUT TAILPIPE (+£3.50)
QUANTITY:
STAINLESS STEEL T304 GRADE
!!!! LIFEIME WARRANTY !!!!
These are individually made for all Impreza model types -
SPORT/ TURBO / WRX / STI
(Please inform us of your year, model and engine size when purchasing.)
5" Tailpipe (or 4"+ 4.5" upon request )
The choices of 2 bore sizes 2.5" or 3"
2.5" Bore is the quieter of the 2 with healthy power gains .
3" Bore is the louder of the 2 with maximum power gains .
Both bolt to the standard and some sports center sections without any hassle or modifications.
All fittings, instructions and gaskets included.
When Purchasing Please state -
Model, year, engine size and tailpipes required, and click on the options available on the right hand side . £165.00 inc. VAT
------------------------------------------------------------------------------------------------------------------------------------------------
I have the full 3"-inch version of this system (inc. 3" centre) but my tailpipe is a 4" rolled-in - looks like a 22B's OEM item. Also, the lack of a large ugly oval back box looks oh so cool. The tailpipe really does exit the bumper straight too.
These full systems sold on eBay i.e. where I got mine from (I won it for £103!!!). I'll try to dig out a link for you later (and every now and again they offer the back box with the rolled-in tail, like mine).
You might think that the relative 'lack' of a back box' might make it too loud, but not so. It releases the flat-four's # dugga dugga # without it being stupidly loud - it DOES sound fantastic from outside!...

...Or there's this one... which does have the rolld-in tail and a modest oval back box - this does look very similar to the v.3>on STi / RB5 / P1 / 22B, for an authentic OEM pattina...

Not saying they are better or worse than any other system, but they are 3" which is what you are after.
The TSL Group N (relatively quiet) sounds good on a full 3" decat turbo back system.
There is also the TSL Firestorm backbox/system that is much louder but not quite the loudest out there. Mine has quietened down considerably now it's sooted up a bit.
