No this isnt your typical exhaust question. If it has been a repost then ill delete the thread.

I Wanted to ask before i purchase a catback. I currently have a Warpspeed y-pipe, stock cat.

Here is my question read it carefully this isnt your typical 350z/g35 exhaust question. I know the VQ30 will never sound like a g35/350z theres just too many differences one being displacement.

I am wondering which catback would increase the sound to around the same sound level as a stock 350z/g35. Also which catback sounds decent with an un-equal length y-pipe?

Im leaning towards the Apexi WS2, because i dont want ricer loud or anything.


If i could hear some feedback that would be great. Thanks.

With that unequal length y-pipe, you're not going to get where you want to be.


I've been through so many damn exhaust set-ups on both these cars, and it's not even funny Mixing between sound and flow.

Without sound clips, this is as useless as an MPG post. All set-ups progressive.

A32


1.) Added custom catback, Magnaflow muffler = cool tone
2.) Added test pipe = more throaty, still cool
3.) Added Stillen 1st gen y-pipe = Raspy as all ricer heaven.
4.) Turbo muffler = Lower tone, stil raspy as sin.
5.) 36" louvered core res(LCR) = FTMFW. Slight drone in 2200-2400, but nothing that could not be tolerated. Gotta love that 1st gen Stillen y (equal length)
6.) Added WSP Y = Tractor sounding/out of sync & drones slightly around 2200.




A33B All w/ 1GCM headers.

1.) stock everything else = Quiet, mousy.
2.) CMB = Nice mellow tone, me likes.
3.) test pipe = Holy rasper ricer boy.
4.) 25" Louvered core resonator + spiral flow muffler = Too quiest, & loss of flow
5.) Substituted 25" LCR for 22" Perforated core resonator = I'm sticking with it. Nice sound, improved flow over louvered core.

Alright thanks for the informative reply. I understand any catback with a un-equal length wont sound too good. But its not going to be un-equal lenght for long (cattman headers FTMFW).

Which catback would you recommend, apexi ws2, greddy sp1/2. i was thinking about the stillen..but un-equal length y-pipe, no resonator...i think i know how it would sound like...crap..

i got the sp2 with budget y. clip is in exhaust clips thread.

its kinda loud. i like it but its a bit loud at times. still when u do step on it u gotta love the roar the sp2 makes. plus last time i checked apexi ws2 catbacks for the 4th gen max were on national backorder. i think if u want to go for something quiet get the cattman muffler and then a bpipe from budget

no what youre missing is the dual pipes all the way back you have room to run 2' pipes with an x-pipe after the cats all the way back to your mufflers the unequal y pipe dosent have anything to do with that if you look closeley the 350 z's/g35 pipes arent exactly equal all the way back close but not that close so in other words hack the y pipe run 2'o'd pipe for each bank to your cats then x-pipe, o2 sensor bung should be there in the x pipe then run your pipes all the way back that should give you your desired effect

Sorry to go off on tangents. but the G35/350 do NOT have dual to the mufflers. Right after the tranny it goes to 1 single pipe with a dual exit muffler.

Im not looking for G35/350Z sound/tone im looking for a sound LEVEL around the same as a stock G35/350. Its not too loud but not to quiet.

Thanks for the reply though

heres another ive been under plenty of stock g35's and 350 z they have dual exaust back to the rear muffler i dont know what you guys seen but i KNOW whtat i have http://www.mjpauto.com/graphics/5033...%20exhaust.jpg and stock or not its all about the concept of having a better exaust note

It's off topic because we are not interested in a dual set-up, or at least I'm not.

Cattman B, A33 rear.

No. The point is even with a very expensive custom job to setup the max like a g35, it sounds nowhere close to the g35 so really has no relevance in the long run. y-pipe, cattman b, and either stock/a33/cattman muffler.

and side note...this has turned into the typical exhaust thread. Time to .

so i take it someone has tried a xpipe and duals with a max and it wouldnt be expensive to setup over your greedy setups cat man setups so on and so on the only diffrence between g35's and us RWD and .5 liters more of displacment which will not havean effect on the sound of the exaust but hey you can be close minded if you want but to speak on what you dont know

Look under your car. The X piping you're speaking of can not really happen unless you hack where the spare tire goes. The G/Z have their engine positioned in a different angle, and their piping is different compared to out VQ30. the .5 will make a big difference, and trying to replicate will cost a pretty penny, and will probbaly mean doing a lot of custom work that is not practical. I mean we all need a spare tire in case of a flat.

no the xpipe will happen before the cats just like the pic i posted earlier ive done 3 motor trans swaps in these cars now x pipes arent wide at all and like i said 2 pipes running next to each other all the way back it can be done cheap as well but if youre not a DIY guy or have no means of a good exaust shop that wont rape you then yea itll get into the 600 plus range + but a maxima first is something i can live with

So your saying the unequal lenght y doesn't affect the exhaust note?

OK

slinky87..i work at nissan as an apprentice tech, ive been under more 350z's then you can imagine...just roughly estimating id say atleast 25 differnt ones(early Z's have tranny issues more or less input shaft bearing noise). There exhaust is NOT a true dual, after the tranny there is a y-pipe so to speak, both pipes merge into one and it runs back to the muffler. tht picture you showed was NOT a stock 350z exhaust. if they had nice and shiny stainless steel exhausts like why would people get aftermrket? Also if you notice the stillen design on the catback, it is a true dual, it also has dual mufflers.

I think im going to get the Apexi WS. I found one for sale, so i think thats how im going to go, after talking to another org member he said he liked the sound of his WS over his WS2.

Thanks for all the help guys!!
