^ I concur. Pretty sure that's why my car stinks at WOT, despite the ypipe and gutted cat and intake/exhaust and all. You'd think it breathes so much better and would be more lean but nope it still dumps too much fuel at WOT.

I need a tune...

 

Oh ok I stand corrected.

 

So an safc tune would be in order after gutting the last pre cat. Ugh, this exhaust tuning is always a wormhole...lol

 

AFC could be done at anytime, even stock.

 

I wish I had done all this when I bought it 100k miles ago..lol. This is the car I "wasnt gonna mod"

 

I noticed today that it IS in fact right after slowing down from WOT that I smell the fumes in the cabin...lol

 

GO Big HALTECH

 

Same here man, same here.

I dont mind the smell but a tune would definitely be good for the car plus would make some more power.

 

Haha...be a bit much for NA. I'm thinking used safc

 

That's what I'll be picking up too...

No cattmans or obxs but well see how my exhaust flows and smells change after install...

 

Shiny

 

Indeed well I'll have to buy the safc and get a bung welded in than that will change

 

You have to weld a hanger on the Y pipe if it's missing.

 

Nah I'll just use a wire hanger...

 

My exhaust is actually unsupported between my y pipe and the muffler hangers..lol. It's bolted so tight though it's like one piece. If I get the resonator welded in I'll have em fab a hanger if they think it needs one..

*correction..the b pipe has a hanger...lol

 

On a side note...getting dynod tomorrow. Should be 65° ish when I dyno too...so very neutral temps.

 

Video plz...:

 

How about dyno graphs...lol

 

Next to a vid of the vq going vrooohhhh,vvrrroooohhhhh,vvvrrrrhhhhhhhhhhhhh,vvvv oooohhhhhmmmm!!!!

 

Yeah I can see one problem though...it always takes the guys 2-3 tries to get a good power run in third without the car downshifting...lol

 

So you do have a hangar stud welded on the Ypipe right? Cause the OEM exhaust has the hangar mount @ the ypipe then the next hangar mount is after the resonator!

 

Nope...but I will have one put on by the exhaust guy if he thinks I need one when I get the glass pack welded in. The y pipe came with a nice hanger, but the way it's supposed to work is virtually useless. Thankfully the back of the y pipe is bolted straight up to the manifold so it's really solid. Not much movement at all from the test pipe to the next hanger back.

 

Just to clear up possible confusion. I have either a thrush or cherrybomb glasspack as the resonator. There are no louvers inside it... Guaranteed. Straight-thru design with perforated core tube. im running no muffler, stock ypipe with non-gutted precats, and main cat...sounds throaty, no rasp, but drone between 1800 and 2200 rpms. Partly due to the idiot who welded my exhaust.

 

^
I HATE the damn 2200 rpm drone

 

I love my exhaust, including the drone and all....Passengers who are not into cars, welp they dont really love it the same.

 

should I just stay away from WSP y-pipe , if I am worried about noise !!?

 

The drone comes from a straight through muffler design. If you have a chambered muffler it won't drone much at all

 

in other words OEM then? awesome thanks!

 

Yeah the oem muffler is actually really nice. It was modeled off of the gtr muffler according to literature.

 

Sorry for bump from the past but..
I had my brother drive my max while I drove his car to hear what my exhaust sounded like and boy.. I didn't realize how raspy my baby sounded until he WOT it.

I believe the stock muffler inlet is 2"? How is it that 2.5" piping works well with the 2" muffler?

(Address performance question then the rasp please )

 

I need to hear my car with someone else driving it...

 

Yeah you could only imagine my disappointment..
I found out that i sound like a rice rocket..
Any solutions anyone?

 

Feel free to chime in folks..

 

Generally, the bigger the resonator or muffler, the less the rasp. The OEM mufflers are giant, so that would probably eliminate all of the rasp, but It will also quiet it down quite a bit. If you like your exhaust loud, then you might want to look in to getting a bigger resonator instead of the OEM muffler.

 

Thanks for the validation Isaac, was looking at the carlonator thread and decided I'll get the same one just with the 2.5" in/out

 

I'm scared LMAO! Mine gets extremely loud going up hills in the 2200-2750 rpm range... To the point where music goes bye-bye if it was at a decent level before the hill.

I'm probably going to be disappointed but there's only one way to figure it out.

 

LOL.. don't get your hopes up.. what's your exhaust system like?

 

Stock with a Magnaflow 14816, I'll record a sound clip one of these days.

 

Looking forward to hearing it, I think it'll sound good since everything else is stock.
