Some custom mufflers were developed for a vastly improved result. I was also running dual outlet pipes (twin setup), and when the car was back in Sydney I changed to a single muffler outlet for a better result.So I would expect that stating a nominal 600rwkw support level would very much take into account the muffler design, size, and backpressure characteristics required from previous R&D. Mufflers that may well work well at say 350-500rwkw may well not be suitable for a 600rwkw application.Brian Link to comment Share on other sites More sharing options...

Who needs a 4 inch system for stock turbo? The way I see it there are cheaper alternatives for the stock turbo that are twin 2.5 or single 3.5 inch systems. I don't quite understand having to buy a 4 inch system with a dump pipe suited to a turbo setup that will max out at 400ishrwkw. That's only using about 66% of the systems flow. If you could buy this system minus the dump, that would be a winner for everyone and I would certainly consider it for my impending build. I am getting a custom dump made so I'd be throwing away 3 or 4 hundred dollars buying this system.you would think nizpro would invest in a mandrel bender and make all the sections in single pieces "looks good"A mandrel bender that can handle 4 inch pipe will burn a hold in the National budget mate. Not cheap at all. Edited 16/05/09 02:27 AM by straughsberry Link to comment Share on other sites More sharing options...

ebxmple Member 1,322 Member For: 16y 9m 29d Posted 16/05/09 07:50 AM Share Posted 16/05/09 07:50 AM I guess it will always will be there for the future with possibly a custom dump needed if changing turbo but that wont be happening for me anytime soon. May be a bit of overkill for us standard turbo boys but hey,its done and done once with only a minor change needed if changing turbo. Cant wait to see these start going on cars to here results as they will be what says all. Same things happened when their cooler came out but after a while people started seeing the results and started to change minds. Link to comment Share on other sites More sharing options...

Ran 11.77 with Boges at the wheel so it want a slouch.Fitted the system and put it on the dyno and 348 all day. touched up the tune to control boost a little better but it really needs the cooler kit.The cooler is here but waiting on some proto type pipes.Boges is taking it to the drags tomorrow so hopefully he can pedal it done the track for some record run.Thanks Nizpro.Cheers Paul Link to comment Share on other sites More sharing options...
