New long tube headers for our cars
 

sooo i haven't seen theses before. they look promising tho. dyno and track proven performance out of the box, and ceramic coating available. am i just late to the ballgame on these?

Long Tube, Equal Length Race Headers (VQ37VHR) :: Monsoon Motorsport

hmmm seems interesting. not sure if this is old or something new.

Looks new, but ghetto as well

idk, i actually kinda like the look. for the price they are a nice way to bridge the price gap between PPE and OBX headers

uh oh! DE is here.

now its a party!

The way they slipped bigger piping where the pipes join is ghetto. It'll work, but it looks ghetto.

technically if they work well then who cares about the look? they are tucked up under a low car lol only person who sees them is you and your mechanic (if you use one).

i'm more curious as to the 23whp gains and what the diameter is.

I agree... BUT if they're going to take the easy bullshit way out, their headers better cost even less.

23 WHP gain for ANY LTH doesn't surprise me. Most test pipes offer like 15-20 WHP of that gain anyways

agreed.

plus it then drops into dimisinishing returns for most of us anyways who are already modded.

seems to be a slightly cheaper, less quality, in stock way to go intstead of waiting for FI LTH's

wonder what the gains would me going from test pipes to these.. we talkin like 8-10whp tops?

probably not even.

maybe 2-5whp.

the majority of gains comes from the removal of the cats which test pipes do on their own.

I gained this with my obx header. I'd invest elsewhere.

was that Gain over the stock exhaust?

Looks Just Like PEE LTH's ..

Agreed. This looks like a well built rip off of the original. FYI, I'm sure these are better than FI's headers in terms of design, they look just like PPE's. PPE's are top notch... And expensive.

I bet it's 409ss

Nice find. Get them Ethan. I'll help with installation

Agreed with the others who said this: those are the same (or damn close!) design as the PPE's, which are ******* awesome. They picked a good design to, er, mimic...

The claimed gain is the same too... but where are their dynos?

The only ways I could see the original PPE design improved on would be (1) Make out of titanium or some other uber-pricey and light metal and (2) experiment with the design further to minimize the slight low end torque dip while maintaining all the gains up top (very likely impossible without some sort of variable runner design).

As to TP's vs. LTH: Here is a(n imperfect) comparison between my 2010 370Z with resonated TP's and Nismo weldina (Y-pipe version) vs. my 2011 370Z with PPE LTH + Nismo take off (H-pipe version). Both runs are under nearly identical ambient conditions and both have K&N panel filters plus the smooth tubes and a tune.

Because these are technically two different vehicles (although, of course, same engine model and on the same exact dyno...), these results should be interpreted with caution -- but I think are informative, nonetheless.

I think we can tentatively conclude that the PPE LTH + Nismo H-pipe set up is far superior up top (a whopping 13 or more whp), but a bit inferior down low (about 5 whp lost in a fairly narrow area).

Here's my "ebay header". Only 13hp/17tq peak but over 20 each in the mid range. Best $350 spent so far.

the ebay mods still cant crack the 300whp mark i see :stirthepot:

:wtf2:

Well my highest was 295HP that day with no tune, with that header, my cbe and my cai and I don't cheat like everyone else. If I was on STD like Z1 and everyone else shows then I actually made 308 untuned :). Not bad for under $900 in parts.

Obx LTH?

not sure. garageline here sold it to me and said it was a protype made for them. BS! its 100% the same as OBX. same with their CBE. its 100% made by TurboXS and they even use TXS pics on their site which TurboXS is made in China.

Think you've told me that before. You must have changed your profile picture.

with that many mods why wouldnt you tune is the better question?

just doesnt seem logical at all to have that many breather mods and not tune it for proper use of the mods. the ECU on the Z is awesome to where i can adjust itself but only to a certain point. probably doing more harm than good honestly.

plus a tune would have brought some nice numbers with those mods regardless of their brand name.....well maybe lol

and yes we all know the infamous Z1 dyno numbers to sell their parts. sorta like the one guy now saying he has 500hp NA with a 100 shot of nitrous :facepalm:

i do believe my dyno session was done on a dynojet as well. cant remember to be honest what dyno AAM uses off the top of my head.

A CAI, CBE, and header is "that many mods?" To me it wasn't. I had more mods to do before a tune was needed. Besides I was still running rich so there was zero need for it. No danger at all.

It was logical to me. Again I had more mods to do and the car was running fine. Slightly rich, no knock, and I only dyno'd it that day to see the safety of the motor and we logged it. Turned out it was safe as hell so no need for further intervention. Even after my new CAI, ported TB's, ported upper and ported lower I ran it again before I got tuned and it was still running rich! Still zero knock! Still no issues. The car IS awesome and can adjust for everything so zero harm was done! At least on my 13. Maybe my ecu is smarter and faster than others. I know I don't have to reset the windows when the batteries unplugged.

Here's every single mod I have. Reds before the tune. New CAi that's 2.75" up from 2.5" except the MAF housing was stock size with Z1 post tunes, LTH, straight pipe CBE, ported TB's, ported upper and lower manifolds. Still running mid 11's with no knock.

And here's what my tune got me that day leaning it out with a little more timing.

thats fine just me personally would rather be safe and tune it than maybe hurt something.

yours worked fine so power to you. well power to you at least, car however i mean a tune could break that 300whp barrier i'd hope :stirthepot: :bowrofl:

Lol that's why I had it dynoed and logged. That was the safe thing to do. If it was lean and knocked the first run I'd of backed off, scheduled a tunning appointment and would of come back after driving like a grandma for a week.

The car is tuned now and is does.

It looks really cool but that's not important. Is the coating worth the extra cost?

I've never seen one last. Chips off eventually. Just wrap it.

stepped headers are nice! definitely not ghetto. even the collector looks good!

Really? That's interesting and the coating coming off. Good to know. Wouldn't warping be more?

More money? Idk, I got this. http://www.summitracing.com/parts/dei-010127

Or this http://www.summitracing.com/parts/dei-010130

Rated higher than a coating, lasts longer, and now that I look back way cheaper too.

The coating on my FI LTH's is holding up great. :tup: But yes, I've seen some that didn't last a year with winter road salt.

well i dont know how much wrap each side takes but for example the coating on the FI headers is $365 extra. with info on how much wrap it requires im sure you guys can do the math lol

you didnt take your Z out last winter did you rusty? :eek:

It doesn't see snow. That's why I have this. :D

i know you have that lol

just making sure. the Z needs it's winter hibernation just like mine. heated garage with a cover on it :tup:

More I think the more I believe I got the 100ft at $79. This did both headers and like 60% of the X pipe. So as far back as my seat.
