Z1 VRX60B vs?

I understand some people have emissions tests to worry about, but aside from those cases LDP's always seemed like a useless mod to me. You are still leaving the biggest restriction present in the exhaust - the primary cats coming off the turbos.

While I've heard some say that you can get some catted downpipes and have the CEL tuned out, that likely won't leave the car able to pass emissions (though I've heard depending on the state you can have one readiness monitor showing 'not ready' and it is passable, but that's very much a 'ymmv/check your states guidelines' type of situation.

If you have no other option but to only do LDP's, you will already be in better shape with those, intakes, cat back, and a tune as opposed to spending all that money Z1 quoted for mostly supporting mods that aren't needed at the stock level.

I did get a bigger Cat Back exhaust.

With these engines I wouldn't go with small turbos.

Bigger turbos= less boost to make the same power + less pressure on the engine + less heat = less issues.

If Greddy release their kit with the 18Gs it would be a big mistake. They should at least offer the kit with 20G turbos.

I spoke at length with Justin at SOHO and he mentioned the same thing with the bigger turbos. Less effort to make the same power, less heat, etc.

But the power comes on later. OK for track not so good for street.

Looking more closely at the dyno charts and speaking with Justin at SOHO it's actually not that much different. It is different, but not that much

Thanks.
