It sounds good g35/350z-ish i don't think so, maybe 300zx-ish :D
it's deafinitely the muffler giving you that little rasp but its not bad, maybe sell that muffler and try a diffrent one out.. if you would have left in the stock cat and ditched the resonaters i bet it would have been a little less raspy/quiter like my set up

Didnt wanna keep the cat. Im building for FI and am trying to rid of the bottlenecks. Resonators are there to get a bit of both worlds (flow/sound)

Can I ask why you wanna keep it all OBX? Just wondering

VQ'rInWLA 08-12-2011 07:52 PM

To be the first of a kind. A pioneer. Ppl tend to be on the fence on decisions for trying or using untested parts/setups etc. Just giving back to the org.

renots 08-12-2011 11:23 PM

I always thought that hittin the rev limiter was bad but maybe not.

An I was gonna say it sounded g35ish but still wasn't sure, I can't wait to hear it tho!!

VQ'rInWLA 08-14-2011 06:11 PM

I think Im gonna end up keeping the setup. PPl did say it sounds different in cabin but its a "good" rasp. (thus g35 ish) I keep getting the same compliments so it stays.

Oh and Jim, raincheck on the BBK. Trying to use my bracket as a template to make a whole batch made.

95Maxed 08-14-2011 06:19 PM

I think it sounds really nice. Maybe a muffler sway would get rid of the rasp, but when your going down the road it sounds amazing

VQ'rInWLA 08-14-2011 08:37 PM

The rasp is really heard from the cabin but im now subliminally telling myself that its that g35 rasp. So alls good in the hood

aackshun 08-14-2011 09:01 PM

G35s have rasp if they just do Test Pipes and a cheap catback, which a lot like to do... So yeah...

Thought Id add a cold start to warm idle sound clip. Starts off idling on a cold start and waiting until it goes warm followed by a few revs (near a wall). Excuse the poor sound quality...I used a cell phone. And yeah, she's very filthy atm...sat in the elements while I was gone :(

carsnwomen91 05-19-2012 09:34 PM

that sounds very good, exactly what i want out of a vq! much better than this **** rasp garbage http://www.youtube.com/watch?v=xiAT3QuVLng. so you get the rasp of the test pipe and the rasp is accented by the terrible tone of an unequal y pipe and stock, unequal shorty headers. you could've edited the 2 min warm up lol, i sat there for a whole minute before fast farwarding :p

i've got WS SS y and 2.5" magnaflow high flow cat and an ebay SS mandrel bent, resonated cat back. http://www.youtube.com/watch?v=J0y98h5PJbA&feature=plcp there's absolutely no rasp at all but i don't like the tone, nothing like a g35 but sounds much closer to an american ohv v6 lol. the idle is nice n burbly though. if you have a stock cat with an aftermarket y and cat back it will be raspy. its a 2.5" much higher flowing collector going into a 2 or 2 1/4" cat and then exiting through a 2.5" cat back. i believe the smaller cat between both 2.5: pieces is creating rasp. all you need is a same size cat as the rest of your single pipe exhaust or a same size high flow cat.

i've done extreme researching on exhaust so i can make my car sound as close to a 350z/g35. i knew any vq, regardless of intake manifold, engine size or engine layout should sound similar so i got to searching. all you REALLY need is an equal y pipe. you can keep the stock y pipe (more equal than current aftermarket y's but not as equal as the cattman or obx) and straight pipe it back and it sounds pretty nice http://www.youtube.com/watch?v=RSG9d...eature=related but yields little gains because he hasn't touched anything before the cat.

you could also get a cattman setup with matching headers or the obx v2 system and make it sound 90% like a 350. infinimax96 has some sick in car vids of him racing where you can truly hear the sound of headers and equal y pipe (obx v2) http://www.youtube.com/watch?v=3Mmzjov17rc

and cattman's http://www.youtube.com/watch?v=jFOKnm5LBqU here this guy is still running a stock b pipe with the smaller diameter piping and a huge quiet resonator so its not fully uncorked. once he gets a new muffler and b pipe it'll sound a lot more like the v2 setup on infinimax96's car.

VQ'rInWLA 05-19-2012 09:40 PM

Its pretty well known by most on here that I have cold start issues so I made that last sound clip specifically to highlight the exhaust note change from cold to warm....

Fly by and in cabin sound clips are within this thread.

And yeah, going = length is the way to get it to sound more RWD VQish.

ahh so you're 00vi'd... i have the same issue except mine misses sometimes on start up, thinking old coils (i'm the 2nd owner of this 00vi 'kit') but the lower high idle to higher rpm high idle sounds exactly like mine

does your start up issue involve:

rough start followed by a slight rough idle w/ no readable afr's for the first 2 minutes at like 1100rpm and then slides up to 1200 rpm (@ 2:58 in your vid) where afr's go from unreadable to 14.7 within a matter of about 10 secs?

VQ'rInWLA 05-19-2012 10:15 PM

DE-k. Been running pig rich ever since I went 3" back. EMU tune coming up soon. And no my idle is just really low at first. Gotta gas it a bit upon startup to let it catch (cold) and let it warm up. Startup idle=550...warm idle=750-800. Once its warm all day, it wont need to be gassed upon startup.

:( lol oh well. thats weird how it goes rich after installing a more flowing exhaust on a stock ecu... the tune will make a world of difference considering all the mods on it already. gonna make some dyno vids? i'd love to hear it under load with the v2's and 3" :happyface

VQ'rInWLA 05-20-2012 03:43 PM

Dyno vids yeah but later on. No time soon. As soon as I get my tags right, I'll take her out for a spin with a bumper mounted cam so you can hear her under load.

carsnwomen91 05-20-2012 07:55 PM

Wooot Thanks man can't get enough of obx v2s clips! there aren't many videos on YouTube with 4th gen and v2s

VQ'rInWLA 05-29-2012 09:46 PM

New OBX rear sec is on. Sounds VERY clean. Similar sounding to cattman/greddy sp/se series.

http://i1180.photobucket.com/albums/...h_M4V00840.jpg

But Im putting the old one back on....clearance issues with my stance :(

VQ'rInWLA 05-30-2012 10:35 AM

Yeah got fam out there who're dying to see me. And vise versa of course!

VQ'rInWLA 05-31-2012 07:16 PM

In cabin sound clips of new setup:

For this one, the raspy siht you hear while I was stopped (1:53) was a nasty azz prelude revvin back just because I was :lol:.

http://i1180.photobucket.com/albums/...th_twstart.jpg

Another one

Terrible attempt at a fly by. My brother is a wack cameraman :facepalm:. Too late to do another one now. Im back to the previous setup.

A guy (2-slow-50) from Cali moved over here and he's flipping out over the fact that you can have intakes and exhaust on your car and still pass, basically you can do anything that won't trip a CEL and you're good.

We're sooooo off topic... WE DEMAND VIDZZZZ

I live in CA.
I have a CAI
Its not CARB legal
I still passed smog legally. :cool: ( I just had to switch back to stock y-pipe)

LOL @ the ricer rev :laugh:

VQ'rInWLA 11-21-2012 11:24 AM

Back in my old thread again. Bought a 3" SP2 to frankenstein it together to this setup. Swapped the can out yesterday. Highly fucckin disappointed....

http://i1180.photobucket.com/albums/...120_222317.jpg

IDK whether to keep going from here and add the SP2 resonator too or cut my losses now rather than hacking it up and killing resale value more than I already have....

Dont wanna go back to the OBX Forza although its the best balance of proper fitment and sound.

litch 11-21-2012 11:59 AM

VQ, just a thought, you tried the HKS can for your setup?

VQ'rInWLA 11-21-2012 12:00 PM

Nah. Im already in deep with experimenting. And I really wasnt trying to stray too far from OBX even though I kinda did getting an SP2.

u <3 obx... AWWW its cute. I get you man. If this thread is still alive when mine gets dynoed I will give you a compare & contrast if you want.

VQ'rInWLA 12-13-2012 09:48 PM

Shiit I forgot to update this. Threw the SP2 resonator on as well. Results:

http://i1180.photobucket.com/albums/...h_M4V00907.jpg

Cam phone mic aint the greatest at picking it up....not to mention being against a wall. Will try for another video over the weekend. Overall, Im pretty satisfied. In a nutshell, can for can, OBX Forza>SP2. Yes I cant believe Im saying it either. The Forza sounds damn near the same way by itself. I can only imagine if I swapped the muffler back on leaving the SP2 res on :drool1:
