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...

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...

Revolution is what I'd go for if I was to get rid of my Nur Spec.

 

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.

 

Here is my old scooby with a 3inch full decat from Revolution on the rollers at Scoobyclinic:

James, someone is currently selling a full Cobra 3" system (centre and back box) on SN!...

Thanks. Flamer kit though

 

I agree but er, you dont have to fit it ... You could then flog it on to the neds

 

hi mate the aps 3" is one of the best,excellent quality,and not too loud but excellent burble

 

Revolution for me.......loud enough driving but quiet enough to keep the neighbours happy

Not loud enough for some though !
