I recently changed my Prodrive back box on my MY00 UK Turbo PPP from the original version to a newer box for the MY05 STi.

I immediatly noticed that the box feels lighter and when fitted to the car is quite a bit noisier especially when warm.

Is the newage box packed with much less sound absorbing material? Is it possible to cut the box open and pack more in. Would this help?

I have been told that the newage box flows better than the Classic so would like to keep it rather than reverting to a Classic box.

Hope someone can help. If not is there someone I can contact who will now?

 

10 years on but i didn't realise a Newage one would fit, aren't the hangers in the wrong place?

 

I believe one of the hanger is in the wrong place, but it will fit

 

Yeah that's what I thought.

 

the two at the rear valance are basically the same, the front one on the silencer box faces the opposite way but most simply ignore with no issues..........

 

Also, isn't the New Age downpipe slightly longer? So, if you were to fit it on a Classic - but still using the Classic centre section and back box - then wouldn't that throw their hangers out of position? (As well as having the tailpipe sticking out beyond the bumper a lot.)

Or am I talking crap?

 

Iv got a newage sti Prodrive full exhaust and Prodrive sports cat if anyone is after one for sale. Has done 59k Great condition

 

the thread was about a back box................

yes the UKDM 2pce down pipe wouldn't mate to a claasic style ecntre / back box due to differences in length BUT you could use a complete system turbo back on each other

 

- That'll teach me not to 'skim read' in future.

- Sure.

 

I was wondering if there's any way of telling from a picture?
