Look at this Thread and let me know if you need anything

[4drmadness]

Hey guys i have been thinking of selling my tanabe catback, and stillen y pipe for a stillen catback exhaust gen 2. I know this guy who basically wants to trade his stillen gen 2 for my tanabe catback and stock y pipe. do you think that would be a good deal. i need to do something to my setup anyway because the tanabe catback is very sensitive and after i installed the stillen y pipe, its giving me too much rasp, and im almost embarassed to drive my car. lol. Anyways let me know your thoughts. I was thinking of putting back the stock y pipe, but i think it would be a better deal if i would go with the stillen. I already have the stillen HFC, so i would basically have a complete stillen exhaust system, except for headers.

If this goes through i might be selling

-oem stock midpipe-oem stock muffler-oem springs-oem shocks and struts-Engine cover-complete oem intake system-oem shift knob-Stillen y pipe

I have a 04 g35 sedan, and all these have been on my car for 3 years, except for the spacer which has been on for a just a month. If you guys are interested in any of these products email me with offer at [email protected]. i will post pics if anyone wants any of these things. I want to get rid of all this stuff so please just shoot out offers, and help a nico member upgrade. Allof these things are out of my car and i can ship as well. let me know guys.

[tollboothwilley]

why are you getting rid of the plenum spacer??

[4drmadness]

want to go with a motordyne one

[tollboothwilley]

why?

[4drmadness]

easier installation of strut bar, looks better, performs better

[tollboothwilley]

doesn't "perform better"

they found that there wasn't "significant gain" to have a larger size. There was some gain, but not enough for size. Higher top end gains with larger spacer, better average gains in low rpms for the 5/16

[4drmadness]

hmmm im just messed up today man. im taking everything negatively cause of the raspiness. i shouldnt sell the blox spacer lol. u need anything stock?

You might want to do some research before you back up that statement.

My understanding is that Tony at motordyne tested all the way up to a 3/4" spacer (which was once offered for sale). The problem is that the spacer's sole purpose is to help those front two cylinders breath. The increase in plenum volume decreases intake pressure which can have a negative effect.

The dyno sheets I've seen show that the 5/16" spacer offers the best gains. The 1/2" improves the peak hp near redline but actually loses power in the midrange. We're not talking huge numbers here, but a rounder power curve is a rounder power curve.

So we could almost say that the larger spacers are for bragging rights and the smaller ones are for actual results lol.

I got the Motordyne 5/16 spacers

[kmckis1029]

damn thought you have a coupe... i wanted your midpipe to hold me over til i buy the stillen gen 2 exhaust next year...

[4drmadness]

lol. im getting the stillen gen 2 installed this weekend ftw. ill let you know how that goes as well. stillen hfc and a complete stillen catback system. should be a beast setup.

they did test all the way up to 3/4 but the reason that they use the 5/16 and 1/2 is because there were some lower end gains that were better with the 5/16...it was a more well rounded gain throughout the band. The 5/8 actually had higher gains but it was more top end. I've done my research.

that setup should be sick. make sure you post a vid up of the sound when you get it on.

I think the rasp that you got is from your cats...but the tanabe seems to be a raspy sounding exhaust to me anyways. Maybe thats why they don't replace the y-pipe??

Either way, i think you will love the full Stillen sound.

[BrandAidDesignG35]

Yeah, this has been discussed at legnth, and I'm hoping this is true John, it seems that the Blox 5/8" Gains were better HP numbers, but only achieved in the high rpm... ie: 4500 + RPM... Like Nate said, it's only in the high rpm... but when your racing... your only in the high RPM

Track tested and proven, I'd just stick with your blox.

I remember when I first installed mine... I was like, hmmm, nothing... then I cranked her open and I was like ... It screamed at me past 4-7,000... like really loud, and angrily like.

Now it just roars outside my car, if I have my windows down it's quite impressive

And the larger spacers showed losses or no gain down below. I love bragging that I make 273 hp at 6900 rpms, but for track and highway use it's pointless.

*EDIT* Motordyne's dyno sheet and the some of the independent testing differs in data. I'm going to bow out of this debate because I don't have conclusive evidence on either side.

Based on motordyne's data, the 5/16 has better gains from around 2500-5300 and then the 1/2" takes off from there with gains of 1-4 HP from 5300-redline.

[4drmadness]

yea it seems like its likely from the cats, but i was thinking why put the stock cats back on when some one is buying my tanabe and stock y pipe for their stillen gen 2. i wanted more power, and i think stillen will be perfect. i know its gona be in top end but thats what i was looking for.

[4drmadness]

BUMP

[Sentientbydesign]

Honestly Vivek, your car is starting to sound like it belongs to a Honda owner.

I consider you a friend, but damn do you need some help in the taste and money budgeting department.

I don't see your OEM stuff being a big seller. Why would any of us want OEM suspension, mid-pipe, y-pipe...etc.

Maybe the cats you could sell, but not for much.

[4drmadness]

yea lol. looks like no ones interested. lol i might need some help.

[4drmadness]

You gotta understand that this the first car im modding. i have so many ideas in my mind, and some are ricey ones. i just want to make this my car. u know that i work for mods, so thats why im being extravagant and buying a lot of stuff. if my car gets too hondaish please look the other way . i know that i dont have the best taste, but im jus havin fun.

[Sentientbydesign]

My advice is to mod for a reason, not just for the sake of modding.

Individual experession CAN be overrated.

I'm modding slowly. Probably too slowly for your taste, but when I'm done. I'll know that I have a very highly tuned G that will be the way I planned it. Not the way it just happened to be when I stopped.

[4drmadness]

that seems fair. good luck with that.

[toddnos]

my thoughts are that while cheaper mods are nice, taking your time, and saving for a mod that has real gains is a much bigger feeling of satisfaction.

nitrous/turbo/SC. ..Or a nice brake set up. or a set of off set rims, maybe even a ECU tune.

just my .02

[tollboothwilley]

Vivek.

HFC's have been known to add rasp between 3-4K rpms

My guess is that the Tanabe sounds very raspy when you add more free flow to it. Get that Stillen and with the HFC's I think you will really begin to enjoy the sound that you get out of it.

As for the OEM parts that you are selling....sell them on that "other" website. There are people that are returning to stock frequently and you might be able to get something out of them.

[4drmadness]

yea im gona put it on the other website, but i dont have permission to post on the for sale section because i dont have enough posts or something like that. The guy i was getting the stillen exhaust from is having 2nd thoughts, he will let me know tmrw. if he doesnt sell it, sould i only remove the stillen HFC or the stillen y pipe as well. kinda confused. I might need to get like professional help or remove one component and see how it is, and if i still dont like it, then i might have to remove the y pipe as well.
