No problem

Also, in all sincerity, I think if you picked up a "take off" Nismo (the one with the H-pipe) at a decent price, you aren't going see much more springing for a different cat-back. Really to pick up more you'd need either headers or at least high flow cats. With either of those you will DEFINITELY need a tune.

With your current mods and OEM cats, a tune might pick some more power, and you could improve throttle response (and shift speed if AT), but otherwise I'm sure you are running safely without a tune at present.

Hey there,

It's hard to say exactly, but probably a solid 10 -15 whp or more over stock at various points in the rev range on a dynojet with SAE correction.

If you search through my thread with all the dynos (search for "proven power dyno" and my username) or look over the dynos in my gallery (most are in "Back in Black") you should be able to get a good idea as several of the dynos are of those or similar mods before and after tuning.

The sport package is totally worth it. For ~$3000 more, you get syncro revmatch, 19'' wheels w/ tires, bigger brakes, VLSD, front lip, and a rear spoiler. Aftermarket wheels and brakes will cost...

All I can say is there is a 100% night and day difference between a Z with an open diff and one with a properly setup aftermarket LSD. To date, with all the work I have done to my car, I still think...

to the OP there is another thread that goes through the differences The Carbonetics is a nice unit. Some (350Z's) have experienced issues with premature disk wearing, even using Carbonetics...

Depending on how hard you drive you can really overheat the VLSD, even on the street. I did it last year at ZDayZ, and there have been other discussions from 2009/2010 about it. But I do agree...

The Z1 Silicone tubes seem to fit better than the HPS tubes, didn't have to trim the passenger side tube at all, perfect fit. The overall quality seems to be better as well, a bit thicker than the...

I installed the tubes and took more temperature measurements. I don't see any difference in temperature between the HPS tubes and the stock plastic ones.....which is pretty much what I expected. ...

I just placed an order for the tubes from your web site and I already have the filters so hopefully the tubes will be in stock soon. I recently installed a Kenwood DNX9980HD along with the...

I wanted to write a small review now that my tubes have been on the car with the K&N drop ins for about a month. I have noticed 0 gain in hp or sound and maybe about .5 mpg increase in gas mileage....

I have had two different types of intakes installed on my z and it's all been a waist of money. Stay stock and keep a fast z. Intakes will make your car louder and slower. You will loose all the...

Its still slow

Fast Intentions, why? because I have it and I love it & because I was told by a really good mechanic that that's the best one you can get. That's it, question answered. Your welcome.

WOW...... That looks like someone stuck a trumpet as their exhaust. Does not look good to me. Actually EPIC FAIL.

It's just inherent to an X-pipe. H-pipes tend to sound "fuller" at lower RPMs vs. an X pipe, which sounds hollow. I used to run a off-road X pipe on my Mustang and there was a hiss-like sound from...

Certain X-pipe configurations cause the hiss. It will be amplified by the addition of HFCs, TPs, or LTHs. I know with FI's X-pipe, even with stock cats, there's a good bit of hiss on decel in...

Coming from owning a G37 and having an SS catback with 18" resonators...and later adding Resonated HFCs, I knew I would be running a similar setup on my Nismo. I elected to go with a NONresonated...
