need some advice on what to use for headers/y on my VQ30.

Im doing an 00vi shortly and eventually SC.
I have a high flow cat, 3" SS tubing from MES w/ 80mm APEXi NOIR enroute....but getting nervous...as i dont have anything in place for headers/y
yet.

Any suggestions?

not sure if the OBX VQ30 is worth it? i hear the HP gains are minimal....and cant find the VQ35s to mod

might just go w/ a warspeed Y as last resort?

appreciate it!

Where are you located? Do you have emissions tests in your state?

I installed a WS Y-pipe with Magnaflow High-Flow cat (also from WS) this spring. I would say that mod brought more bang for the buck than anything I've done do date outside of a bunch of suspension mods..

The OBX VQ30 headers are ok, its the y pipe that they come with that does not line up. You can either cut and weld the y pipe to fit or chop the y pipe off and make a new one. As long as you're in there, it wouldn't hurt to add an o2 sensor bung to the front (bank 2) header where the o2 sensor can reach.

I live in Mass....and was got the heavy loaded cat in case for emissions.

Does your warpspeed sound raspy/ricey?

thanks - Im crazy busy with work and dont have the time for the custom work - Im taking time off to do my 00vi....this doesnt seem worth the effort when I can get 15-20hp with the bolt on warpspeed Y....assuming it doesnt sound like a rice-rider

The WS alone is not so bad. I have a high-flow cat with a glass pack and straight pipe with a silencer. If the silencer is out -- no doubt it is loud. The silencer makes it cool for around town. Fortunately, the V6 sounds better than the typical 4-cyl ricer. I've listened to some youtube vids of Maxima's with a Y-pipe setup and stock resonators that has a nice deep tone.
