I know many people on here with a supercharger are getting good gains with headers and 3inch y-pipe compared to the regular y-pipe ( stillen, budget,wsp, but which would you think gives the best gains? I know that 3inch is good for top end power but also are headers but which do yo think better? not being one costs more or cheaper than the other just peformance wise.

Which do you think gives better opposed to each other?


1) y-pipe (stillen, wsp, cattman, bugdget)
2)hotshot/ cattman headers
3) wsp 3 inch down pipe
4) shorty headers

 

sorry i could edit the poll title , but u know what i mran

 

I voted 3" y-pipe pipe but everything you have listed there will really need a "mode of realease"....What I mean is, everything you have listed there increaseses the air flow alot out of the motor but if thats ALL you have you will see very minimal gains from it. What you need is a full 3" exhaust or a 3' y-pipe matched with a stock cat-back and a 3" cutout that you can open when you want it ( get the driveablitly of a really quiet exhaust for every day driving, then when you want it, open up the cut out and wake the neibors)

If you do a full 3" exhaust RIGHT, it will not be loud. Quality muffler, and quality perferated core resonator

thanks matty for response

 

I would call Cattman and ask him if you could make me the headers but instead with a with a 3 inch collector. and then get a 3 inch exhaust.

 

from what i read both the headers and 3 inch ypipe have good gains but i trying to get to where does exactly how one would be better as far as powerband and were the gains are 3inch ypipe and headers does any body have a dyno's to compare 3inch ypipe vs headers with sc.

 

you can only use cattmans headers and the y-pipe that comes with it.

 

I know that . i am asking which one is better than other headers or 3inch ypipe with asupercharger? which one gives better gains then the other?

 

My plan is since I allready have the headers is waiting for the cattman 3 inch cat-back.

 

I don't know if I'd call the gains minimal.

Here is what happened when I went from a 2.5" setup to 3" (Y-Pipe back - still stock headers) - nothing else was changed:

 

try searching... I believe Stephen Max did some before/after dynos on his supercharged max with Stillen headers

*edit* here

 

i went with hotshot headers and 3" boost actuated cuttout. I figure its the best of both worlds

 

Los I never seen a dyno chart of a SC max with 3'' y-pipe before, but I have seen a SC one with cattman 2.5 y-pipe in comparison with their headers. If remember correctly, the gain was about 11whp (the guy made a total of 340whp in a 5gen).

 

Where did you purchase the Hotshot Headers bro ?? do they have the stock flanges on them for the y-pipe ?? Anything need to be cut ??

Thanks

you can get hotshots headers through hotshot here the link

http://www.hotshotperformance.com/ho...ers/ns3017.htm

no i dont think the have stock flanges for the y-pipe becuase they send u there own and these are only made for the 3.5 liter , but they still work on our 4th gens. There not like the obx ones i dont think you have cut anything to get them on only obx i remeber being the pain in the *** to put on.

I seen the shoty headers in person and i personally lined the flanges up the oem y-pipe and they fit exact so you will be able to use those with aftermarket ypipe 2.5 or 3inch. but the only thing is with the shorty headers they look like inside the holes sto be ported out some more the holes look really tiny for headers.

 

ghase we all know there is a big diffrence between the 2.5 ypipe with sc and headers and also the 2.5 vs the 3inch ypipe , but which makes more power between the 3inch vs headers? That the question if two 4th gens running the same size pulley with exact manifolds and injectors and tuning who make more power if one was using headers and the other was using 3inch exhaust?

That why i doing this poll to get opinions, becuase both give good gains but which is better?

 

Well what are the Shorty Headers that someone was selling on the .org about a week ago ? They look pretty stock me

-matt

 

Well they fit the same and are not really any larger terms of exhaust size than than the oem ones. I think the ones i was playing with (which these belonged to a friend). He had bought them off ebay and i am not sure the brand thou but they have been referenced on the org as being the shorty headers , matter of fact the set he had came with a ypipe too. They came as a set of three pieces to headers and a ypipe . The headers thou did line up with the oem ypipe flanges.

 

i think, unless u have a 99, all our pre cats are in the y pipe not the headers....but thats N/A talk...as far as boost goes...someone posted a dyno result, and went with headers on a 2.5" full exhaust setup and got 20whp gain with just headers (SC)...iansw is showing wut happens when he changed everything else...so u can use that info to compare the two... regular y pipe shouldnt even be up there as an option...

and not to hijack, but can someone link me to where i can find a retailer for 3 inch cutout exausts, or explanation?

 

by the way ppl are gonna vote cattman headers because they assume ure talking about the headers that come with the y pipe....and also its cattman.....

 

Maybe i am typing in japanese, but we are not alking about 3inch cat -backs vs 2.5 cat back We are discusing headers vs 3inch ypipe and which one has proven better gains with a sc that is the discussion. This is what i am using so others can compare also. smart guy ..........j/k

 

lol, jerk...that wasnt wut i was comparing, i was comparing a set up where they changed just the y pipe back, and one where they changed just the headers...., get shorty headers, 3inch y pipe, and 2.5 with 3 inch cutout...thats it, i have spoken....go do it now....

 

lol u would be the only dumb *** willing who would by all exhaust componets. u got the money. so u go buy all them , install them , dyno, then repeat and let me know which one works so i could post it money bags.

 

naw....my vote is on cattman headers.....SC = u must have money, u know that already....in if/when i boost, i damn sure will do wut i said....

 

yeah i was i had money too do this also. damn i need a good job
