I am getting a little bored with my current exhaust system and want something to give a bit more rumble. Currently have a 2005 sti with the prodrive pack, so basically prodrive sports cat and backbox. I want to keep the current sports cat too, so don't want to decat.

I have been looking at the Milltek non resonated centre and backbox, has anyone made the change from standard PPP to the Milltek, and where you happy with the results?

Also are there any other alternatives? I was looking at the Ninja 2 silencer only but I am not a big fan of this style of exhaust (the look, not the sound). I just want something that burbles a bit more, and will give the odd pop and bang without going all out fart cannon.

 

afterburner vortex

 

I couldn't wait 5 minutes after posting and ordered the Milltek, will try to get some before and after videos posted next week

 

I was in the same predicament as you last month. I too have an STI with PPP sports cat, decat, standard centre and PPP back box. I recently bought a milltek backbox from a member on here. It's a little quieter if anything while driving, but on hard acceleration it comes to life and sounds incredible. I'm looking to mate it to a matching unsilenced centre in the very near future for a bit more sound. Did you go for the unsilenced version in the end?

 

I also had the Prodrive exhaust on mine. Now have this one.

Lovely deep rumble, but not silly loud either.

 

NUR SPEC R

 

I went for non resonated version, hoping there is a bit more noise than standard PPP

 

Good stuff, will be interested to see your thoughts when fitted!

 

genome,blitz or invidia n1
milltec is silent -sounds poor

 

if its silent how does it sound poor................

 

We will see next week. I had looked at Genomes but too rare and expensive for a second hand back box.
Invidia and nur spec is the complete opposite of what I want.

 

The place I ordered this from say it will be 2-3 weeks as they are waiting for stock from Milltek, so might be a while before I get back to you.

 

I have the Milltek non-res cat back with the Ninja race cat from Scoobyworld and I think it sounds great. It's loud enough to hear when cruising about town, but when you hit the throttle it really opens up and sounds fantastic. It doesn't drone either which is good if you do long journeys. Oh and it passed its MOT last week with flying colours
