srobrien Posted August 2, 2009 Posted August 2, 2009 I am thinking about an aftermarket exhaust and am deciding on the K1 or K2, I love the sporty look and sound of the K1 and am more weighted towards that. The thing I am wondering (bearing in mind i know little about exhaust systems) since the K1 is a "straight through" system will this hamper any possible power gains from a remap due to an uneven pressure balance in the system? i.e If i am after powergains should I stick to a backbox? Cheers R Quote
IanS16 Posted August 2, 2009 Posted August 2, 2009 Best person to ask would probably be Adam@Z1Auto. Me and nurrish have both been dynoed at over 300bhp (fly) and we both run the K1 though. Quote
srobrien Posted August 2, 2009 Author Posted August 2, 2009 well 300bhp aint half bad, the difference in the 2 would probably be negligable then. Decision made.......almost. R Quote
BladesGrant Posted August 2, 2009 Posted August 2, 2009 Hope your friendly with your neighbours!!! I have just had the K2 fitted, really happy with. Heard Ians and Nurrishs and it's going to just be what you prefer, hopefully going to get tuned this month so might see some differences but think they will be minimal. Quote
GT4 Zed Posted August 2, 2009 Posted August 2, 2009 K1 all the way baby I was reticent about the K1 about being able to live with it daily and this is so with bungs on(reminds me of my Tuscan ) and then when i want to play for limited periods only bungs off Quote
pyn888 Posted August 3, 2009 Posted August 3, 2009 i havea K1 just now and just about to switch to K2 K1 sounds great and looks great but i cant live with it on long journeys and it just doesnt look right with the bungs in i know once i get the K2 fitted ai am goign to complain its too quiet though Quote
Chris`I Posted August 3, 2009 Posted August 3, 2009 K1 will help you get more power if you have a remap. It might make you run a little lean until then as the stock ECU might struggle to give enough fuel for the airflow, but nothing dangerous. Dont think it will loose you anything at all Quote
srobrien Posted August 3, 2009 Author Posted August 3, 2009 Hmmmm mr DHL may have a delivery for me tomorrow morning from CS! R Quote
pyn888 Posted August 3, 2009 Posted August 3, 2009 just got K1 off and K2 fitted what a difference car doesnt even sound like its started now that the K2 on , i miss the K1 already although the K2 does suit teh 350z much better Quote
BladesGrant Posted August 3, 2009 Posted August 3, 2009 I do love my K2, certainly best thing I have bought so far. It actually makes the Zed sound like should (if you know what I mean!! ) Quote

It actually makes the Zed sound like should (if you know what I mean!! ) yeah i ve not been in stock standard Z before so is hard to judge how it should sound, all i could hear before was the K1, i hope the K2 gets a bit louder once some carbon builds up oh well looks like i need buy a plenum spacer and cai to add some more grunt :O Quote

The extra sound and grunt were great, wanted to enjoy the engine noise before going for the K2. I just love the sound of both and they compliment each other so much. Quote

The K1 obviously suits the Zed when its a highly modified monster like yours. Quote
nurrish Posted August 3, 2009 Posted August 3, 2009 No.... i mean this being your best mod and the best thing you have bought so far..... Quote
