--- Quote from: Adam0604 on February 13, 2016, 07:29:44 pm ---Yeah, I'm definitely going to be getting a full turbo back system
Just undecided on whether to get decat or 200 cell.
I want decat, but worried about MOT
So when hoping Nige will be able to advise difference in performance between the two when I ring in coming months.
Also don't know difference between the two different full exhaust systems he mentioned on the group buy thread, so want clarification on that when I Ring as well.

200 cell all day mate. It's more expensive, yes, but you dont lose flow over a decat with these like you might do with other exhausts. It's oversised to compensate.
I couldn't be arsed with a decat with MOT and all that so it's the obvious option.
Powervalve Nige:
hey Adam - happy to chat at any time to discuss all the variables with you...
Cheers
Nige :happy2:

Ah never mind. I've decided to spend out on new wheels and tyres instead.
Will be in touch in the summer though!

You'll be very happy mate. I did LOADS of research on it, watched all the videos, studied the before and after dyno graphs, and I made my mind up to just do it. I couldn't find a reason not to, and I'm the type that deliberates for months over pros and cons when it comes to mods. I couldn't find a reason not to.
I had expectations, and it's blown them out of the water. It's unbelievable. Looks, sound, performance. It's special. There's no other word for it.
And dealing with Nige and the team is an experience in itself. He looks after you. He's so switched on and he's got a damn good team behind him.

Have you got the full turbo back system? And this powervalve thing just bypasses a silencer under load for more noise like the R32 yeah? I'm like you, I need a lot of convincing and research because I'm not unhappy with the OEM exhaust, I just want to reduce EGTs to allow a bit more boost and timing.

Yeah, full turbo back Powervalve mate. 200 cell oversize cat. Proven power gains. 3" all the way.
My normal Sports Powervalve is a little louder than oem off boost, but with a much deeper note and some nice crackles and burps on the overrun. All very subtle. On boost it's full on group b rally. It scares pedestrians.
I'd suggest the Prestige Powervalve. Same as mine but with a bigger front silencer. In fact Nige could make a system as loud or quiet as you want.
Great exhausts.
AJP:
Just to add, there's no drone on the motorway. There's a sweet spot at around 80mph indicated, where it's pretty much silent on a tiny bit of throttle (enough to maintain that speed).
Also worth noting the fact that back pressure and EGTs have really been nailed. I think it was danish on here that swapped to a Powervalve from another performance system, running a big turbo setup, and made the same power at 1.5 bar that he was making at 2 bar with the other system. The info is in the Testimonial section on the Powervalve website.
Nige is creating exhausts at the very top of the game.
