Title: Milltek Help !!
Post by: gazrn on July 10, 2014, 10:11:41 am
Hi I am looking at Milltek catbacks online and there seems to be two different types on non resonated, an ec approved and a non ec approved (smaller volume rear silencer) can anyone tell me if there is a big difference in sound between the two and in everyones opinion which sounds the best ?

Cheers guys

Milltek non res is only a bit louder than the stock system, had one on my last GTI. Just ordered a BCS Sport cat back for my ED30. Loads of happy owners on here that have them. :happy2:

I don't know what level your car is power wise but, we (the shop i use here in Denmark) have a customer with an Octavia VRS with a fully built engine and GTX3071R turbo which ran a full Milltek system 2,1 Bar of boost and made 445bhp. When it was changed to a non powervalve system from BCS he makes the same 445bhp but at 1,5 Bar instead  :surprised:
Thats' a whooping 0,6 Bar lower pressure on the system with same bhp  :surprised:
So for lower backpressure and less strain on the whole system, i can only recommend BCS or similar systems regarding back pressure.  :happy2:

Had a milltek catback non resonated fitted to my GTI about a month ago. As said not a lot louder than stock, until you plant it or lift off at high revs.. Glad I went with non res for sure.

Yeah I'm set on a non res but there seems to be two types, ec approved and non ec approved ? Is there much difference in sound between them ?

I've got a Milltek TBE Non Res R32 style exit sounds savage on boost.

I would google what the EC means. As another Miltek user, I'm not overly impressed with mine, not much louder and rear silencer is huge and hangs below the bumper. I'd go for a BCS system if I had the chance again.

I think ec is European compliance, I'd get approved if it were me tbh

Milltek resonated is just pointless
