You guys aren't doing any before/after dynos, are you? So we don't have a measurement on gains, right? (I'm not knockin' -- just asking.)

i have a stock dyno run from K&N because K&N is using my car for the R&D on there intakes. the car has to go back in november to get fitted and dynoed again to make sure the K&N intakes are perfect, so when i go back ill ask them to do a run with just the exhaust and without the intakes cuz im curious as well

Im scheduled for 3 o'clock.. they are doing GTM resonated test pipes and adjusting the exhaust..

i may not go up there tomorrow now cuz the new pipe from HKS is coming the first week of november so i figured i would go up there the first week of november and get the new piping from hks and the cats installed and the suspension adjusted

Looks good bro.... Can't wait to see the gains... post a video so I can hear how it sounds...still figuring out what exhaust I want to get....

im def going down there, haha, see you tomorrow

posted one of the videos in the OP under the pix, thanks to SEMTEX's help

well went back to amplified today and got the exhaust fix and HFC's installed. the exhaust note sounds even better than before and has a few more ponies. still no droning, did 75-80 all the way home and still hear nothing inside the car, but outside is a very exotic sound and is pretty loud. overall im very happy with the exhaust setup. thanks Lou again for hooking me up!

new pix have been posted in the OP and the HFC's are kinetix.

im going to sleep, im tired

nice vid sounds mean

I'm glad your happy R. :tup::tup:

I'll keep you posted one your new mid pipe arrives from HKS.

updates on the new vid? NEW VID! in car! Drive by! wooooooooo

:P

Nice vid! What was that little stutter before takeoff? Thats caused by the throttle lag in a MT right?

looks pretty.. not a fan of the sound tho sorry bro :(

Ya an updated clip with hfc installed would be bad ***. I am looking to get HKS soon. This would be a helpfull tool for many wanting to buy the HKS and HFC's. Thanks dude the setup is nice.

How much power can you put out with this exhaust before it becomes a bottle neck??? If I were to do a turbo set up with only about 450 hp would this restrict power??

sounds great man! good choice!

I had mine installed along with an amuse catdelete. I'm happy with the sound but not as impressed as the videos/sound clips from stillen and 5zigen.

Unfortunately, I also installed hks intakes and I LOST POWER. From 268 whp to 257, dynojet. We let the engine cool and put ice on the intake tubes and engine and it produced 275. The Shop engineer thinks it's the intakes and suggests that I put back the stock box. Admittedly, it's about 4 degrees warmer, but that shouldn't result in dismal numbers.

Well try to do some custom intake box/enclosure and see if it gives cooler air. If not, it's back to the stock intakes. I hope hks kansai produces a similar intake box seen in evos.

Nismo 370z

nice exhaust, looks awsome, cannot be any hotter!!!
what is the weight savings and power gains compare to the stock?
