Newage exhaust Q adding to the prodrive?
Hi All,
I have a 05 reg uk300, with the PPP as std, I have bene doing a lot of thinking about changing the exhaust, ideally would like to keep the prodrive back box and replace the other sections, i.e. centre pipe, middle de cat pipe or/and even downpipe. I understand it would have to be 2.5". Just after peoples views, good/bad, what gains theve noticed etc as I am aware many just go for a whole new turbo back system in 3". Hope this makes sense Cheers |

Hope this makes sense Cheers What gains from 3" against 2.5"? 3" is louder than 2.5",2.5" will be restrictive at around 400bhp+(on some cars make with 2.5" 450bhp) On 3" you will be restrictive,just your pocket(i mean deep pocket) Jura |
Thanks for your reply, yes noise is a factor for keeping the 2.5", I believe the prodrive is 2.5" therefore would go for the rest in the same yes, are you saying you would recomend a remap after swapping just the middle cat and centre section ? I woul dof thought a remap would be a must if I did the downpipe/cat.

But if you want change Downpipe to Decated Downpipe,you will need remap. Jura |
That clarifys what Ive bene told already. Hopefully ill get some feedback from people who have kept the prodrive and added to it.

I've got the prodrive back box on mine with a full decat. The only part which is 3" is the turbo downpipe, but that goes down to 2.5" before the next section joins it. Mines a 05 WRX with TD05 and some STI parts and runnin 317bhp at 1.5bar. A 3" system would lose you a little bit of torque over a 2.5" at these kinda power levels too

I'm running 330 bhp / SC36 Turbo / Full decat with 3" down pipe down pipe into 2.5" centre into Prodrive back box.
Makes a very nice sound but not too noisy. |
