I'm looking for advice on what I could
do to make my Evo sound a little bit
meaner. I feel as though since I spent
close to 600 bucks it should sound better
than it does, but being that it doesn't
sound that great, I feel as though I need
to do something to make it sound better.
So my question to you is... what would be
the best thing to do to make it sound better
but not incredibly louder, just a little bit
louder. Along with that, where could I get
this and how much would it cost?

Thanks alot.

 

Get the Y-pipe from stillen or cattman, and also get a cone intake or CAI, I'm sure, it will sound, real real mean.
Good luck.

RPNY.

 

I agree... a y pipe and CAI will make your car sound meaner.

 

These two posts bring up several other questions.
1. I already have a JWT cone intake, do you really
think that a CAI will make that much more of a
difference sound wise or performance wise?

2. As far as the y pipe goes, how do they both
compare to one another as far as price, hp gains,
and decibal levels?

3. Will an exhaust shop install a y pipe for me
being that it's before the cat?

4. Will a high flow cat make any sound changes?

The reason I feel I need to make a change is that
the exhaust sounds ok, not great, in low rpms, once
I reach about 3500 the hum is lost.

 

Yes, the CAI will make a difference performance-wise. You can't see the CAI gains on the dyno, but you will definitely see better 1/4 mile times.

Both y pipes will increase your noise level, especially with an aftermarket muffler. Since you're on the East Coast, I recommend the Cattman pipe because it is SS. HP gains will vary depending on what mods you have on your car.

An exhaust shop might or might now install it for you. Try asking the East Coast forum(s).

The cat quieted (is that a word?) the droning on my car.

With the CAI, you'll hear it once you get past 3000. I'm sure you seen this already:

PR CAI, Stillen Y, Stillen muffler...

 

Have you noticed any real performanc/power gains with the Greddy? Just curious if you have done any dynos as well? I agree once you put the Y-pipe on your car is going to be way louder than it is now for sure!

 

No I have not done a dyno.
But if there is any gain at all
I would say it pulls a bit more quickly
when I am already going like 45-50 mph.
I really feel a loss in the take off.
Like 0-60 mph.
Hey kev sounds really good. Are there any
more of those Vid links you could send me.
Or any how to's on the CAI just want to
see what it takes to change it....
Thanks

 

Nope, no more NA vids.

Pioneer has a good CAI writeup. I believe it's also stickied in the How-To thread.

 

whats up dude.. i'm expecting my PR CAI in the mail any day now.. if you want, we can meet up when I install it so you can see what it's like if you have any questions.. just let me know

hopefully it'll persuade you to get one

 

I have no proof & Kev is a lot more knowledgeable then I'll ever be ... but the debate of SI vs CAI has never been settled one way or the other ... right? I thought Cheston was a huge supporter of the SI ... they even performed a multitude of crazy-as$ tests at one point .. or was it Nabil?

n e ways ... loss of low - end .. is that from the JWT or catback? I felt a noticeable loss in low-end with the JWT ... the Y-Pipe more than made up for it @ all ranges of the RPM band ...

 

I have the cattman y and RT cat with stock b-pipe and muffler currently. The car has a pretty nice growl to it. Its not loud at all, but sounds kind of mean. The cat did get rid of some of the raspiness and added a deep tone to the exhaust. It sounds nice after 4k rpm. Anyhow, if you get a y-pipe, it will surely make the exhaust a lot meaner.... VROOM VROOM

 

Email me in advance and let me know when you might
be installing it. If I am around and not doing anything
I would definetly like to see what the install is like.
Thanks
I should be getting my max.org stickers in the
mail any day now. Maybe I can install those
while you install your CAI.

Those stickers are good for like 5hp so I've heard....
Thanks
Howie

 

let's see....i didn't know you didn't have a y-pipe, so when i first read this post, i was like 'what the...'....

anywayz...yeah, the y-pipe will make it much louder..trust me...mine is loud...

i used to have just the Stillen hi-flow before and right after my exhaust..recently, i've converted my intake from just the cone filter to short-ram air set-up...bascially shorter CAI...the cone still sits in the engine bay but the rubber piece is replaced by annodized aluminum piece...it's much meaner sounding in the higer rpm especially near the red line and when i let go of the throttle in the top-end...

i took my car out for the Willow Springs race-track last Sunday...i was having a blast...no cops to cite me for noise-violation...

 

Is it really that loud? Not unbearable, is it?
I wont regret it will I?
About what did you pay for your Y pipe?
Will it make the torque better? (0-60)

Is there anyone in your area maybe at a
mini-maxima meet or something, that would
be willing to let you use there Video\Audio
recorder? In order to post something we can
see and hear, for the entire ORG's sake
and mine of course.

 

I took the liberty of #ing your questions ...

1. Do a search for Irvine's orig post ... titled .. My Greddy Catback is freaking loud! That should answer your question

2. They had / have some used ones throughout ... Alberttan & someone else was selling theirs for $300 shipped .. phenomenal price!

3. YUP!

 

maxin i just went from a stillen intake to a PR CAI and it feels a little better on the low end, my stillen intake was taking away from low end but so far it seems the CAI isnt as bad, havent driven much with it yet though

 

The tests cheston and Nabil did showed the SI gave better top end for 4TH GENS. Because we have variable intake runners, we breath completely differently and get a ton more power up top after 5200 than the 4th gens. So, their research really doesn't apply to the 5th gens.

From real world testing between almost identical 5sp maximas, the CAI has a little more pull at low rpm in 1st 2nd gear than the SI. In fact, I'm gonna change to the cAI.

Dynos are in my sig. Ignore the dyno with UDP, it appears to be an error.

 

With my exhaust setup.
Punching out the cat and having a y pipe and custom b pipe will make your GReddy sound much much better

 

i havent read the whole post but does it have the resonator on it possibly?

 

Hey nice tail lights. They look sweet tinted that dark, or painted to match your body color. They look REALLY nice that way. Sort of GT-Rish which must give you a few extra ponies.

 

i bought my y-pipe way~~~ before my exhaust...i think i paid around $340 for the y-pipe...and yes, it helped my mid-top range...quite a bit..i could see the rpm needle just swooping up after 3,500rpm...but the exhaust added little bit more top end to my car..and this was felt at a drag race track...

i don't know if there're anyone i know who has a video camera in Irvine...i know Mr. Nismo has one but he lives no where near my town...

the noise is not unbearable..but then again, that's also a subjective field...you might find my exhaust noise unbearable while it could be music to my ears...
it's loud and it gets louder in the higher rpms...but i like it..i really liked how my car sounded like at the Willow Springs track.

 

10hp to be exact, i had it dynoed
