Don't touch the up pipe, the headers and upipe and just right as they are, even Harvey couldn't improve on them...and they were his words , Miltek do a sports cat and a decat downpipe, both of which come up for sale second hand, I've got an RCM sports cat system on mine with a Blitz NUR back box, It's a little louder that what I'm used to coming from a miltek but got a DB test at 101db at elvington so not too bad :/

I'm in the same boat as you all I no is classics all this Newage / twinscroll malarki is new to me also so learning as I go along....

I think scoobynet needs to set up a section dedicated to twinscroll so all the info is stored in one location just a thought


It's already stored in one location...... my project threads!


I've tested the **** out of the twinscroll.

That was a pathetic answer though. lol


Depends on what size blower you're going to run, as the boost will then be very relevant.


I ran a GT30 sized core @ around 1.8 peak and tailing off to around 1.7bar at 7k. That was enough for 490bhp on Methanol.


All on the OEM bottom end of course.

I had the nur spec on mine fully decatted and it was unbearable,seriously loud. I had the nur on my Classic STI decatted and was no where near as loud as my twinscroll. I actually had the police round after getting 3 complaints from different neighbours,changed it for an afterburner vortex.

I tried a Blitz NUR on my Blob spec-c with full decat and it was mental...fitted and removed it the same day and went to a miltek back box which was perfect, The Hawk ive got has an RCM sports cat and centre with Nur backbox and its not too bad...It was noise tested at 101db...Time will tell if i can live with it but its nowhere near as loud as my blob was.
