I just received my Nizpro 4" system. This thing is a jaw dropper when you see it in real life. It's huge. I will post up the details on how the fit up goes because I know that their has always been some concern surrounding this system in regards to fittment.

that looks very nice, a mate of mine has one and he seems to like it a lot

That looks awesome !! Will be interesting to hear what it sounds like

I thought only nizpro and nizpro sellers fit them because there such a pita?

But they sound good and flow awesome you'll be wrapped if your after a quiet idle and tuff nite when under it. Think there will be some swearing during fitting though.

hay spoolxr6. nice system Nizpo 4 system.. what power r ya hoping to get out 4inch system mate.???

seems like a waste with twin tips at the end ...

^

Why? I saw a fg on stock boost pick up 40rwkw with just one of these. Rated at 600rwkw by nizpro with cats in place.

I'd say going off the rest of the system that the rear twin tips should merge and then taper pretty well unlike the xforce which looks aweful inside.

The twin tip is quieter though than a straight through rear muffler and that nizpro rear muffler looks HUGE which will be even quieter, or atleast should be!

Hey mark. I'm not aiming at any specific power level. Just want to ensure that back pressure post turbo is minimal for the new turbo.

Mic the design of the rear muffler is real good. It comes in 4" and then uses a y design and goes out to true twin 3" tips. Looks more standard than a 4" Canon in my opinion.

I'm in the trade so was able to score one. Nizpro ran me through the installation and these are test fitted before they are sent out. Basically when you install the dump and cat you have to shift the Turbo slightly via the four bolts that mount it to the manifold to ensure you have the right clearance at the cat. Once this is set the rest of the system will follow. A couple of mm off at the front can equal about 10mm out the back and a lot of swearing lol. Let's not forget that this is probably the largest system you can fit so it will take some tweaking to ensure a snug fit. Then again talk is cheap so I'll keep you all updated with some pics and info on the install.

good luck with it mate. 4 inch nizpo system makes good power.. cheers mark
