I'm planning in installing a y pipe (down pipe) on my 99 Max.
I have some questions about Y pipes:
How loud would the car get if changing only the Y pipe? ( I have the 2001 variable exhaust muffler installed.
Would I lose low end power ( my max is auto)?
Should I have a problem with the emissions?
Does the gas mileage vary, would it get worse?
which y pipe would be the best?
and last, how many HP would I get?

I will do my best

Actually not too bad. At wide open throttle you will hear it more but it is reasonable. I have the warpspeed pderformance version and love the sound.

I have a 5 speed maybe someone else can answer better.

Drive it around for a bit before (like 10 minutes or so) and you will have no problem.

Better actually. It allows better airflow making the mpg go up slightly. But alot of people think it goes down because when they first get it they are driving harder and stuff testing it out.

Like I said I love my warpspeed.

Roughly around 15+ HP.

Great choice

you got questions.. i got answers..


if its just the y pipe.. its not going to be loud at all.. a nice sound at WOT..


no

technically its illegal to remove your two pre-cats.. but its been proven that if you warm the car up first... you should eek by..


shouldn't really matter

in my opinion? cattman.. but thats my opinion..


probably 7 - 8 wheel hp

I cant believe this you guys even compete here , but Sprinty will help you out though, and give you some good facts etc.. ,

as for my reply Son go and get a Y pipe you wont regret it trust me, it will increase your horse power. As for what name brand I personally like my Cattman.

Eric L.

I just had a Cattman SS Ypipe installed and the noise increase is hardly noticeable. In fact, all you hear is an increase in idle noise (turns from quiet smooth to a slightly less refined sound, but not too bad). In terms of power, expect approx 7-8hp to the wheels without an intake, approx 10-12hp with an intake. Don't confuse horsepower to the wheels with hp at the crank.

If there is any loss in low end, I have not noticed it. I do notice that I can spin the wheels a little more easily now, which suggests extra power on tap.

Craig Mack

And you are automagic right !? Yup it seems the better air flow has made the power to the wheels greater and spinnage is easier. aint i a genious

SuDZ

If it helps any just remember. You max is much faster, and better looking than mine.

For now.

boy don't you know how to kiss a$$

clee130

No, because you spelled "genius" wrong.

SuDZ

nah just saying, you got the rims,the tails, the clears, the drop, the Nitrous. All things I want. But dont have yet. No need to start kissing though.

oh UDP

SuDZ

Your pretty much against the UDP huh? I never got to run a before and after test really. By the time the weather was nice enough I installed my Ypipe.

congrats on the y pipe.. i love mine i should put the stock one on so i can appreciate the power again

SuDZ

I might try giving the clear tails a run on my own eventually but if I decide to buy them from you do I need to send you mine or do I just buy new ones through you? This is not for sure but just thinking.

2 options

1) you send me $170 and you come pick them up
2) you send me $190 and i ship them to you

i will never see your stock tail lights..

SuDZ

Ok cool I will keep that in mind if it ever comes down to it.

Thanks

Get the Y-pipe, you'll be very happy.
You shouldn't notice much (if any) noise difference.

I prefer Cattman's Y-pipe.

why warpsped is superior

Sudz.. i am here man.. you need to find me.. i don't sleep .. i post 24/7 .. i never log off..

SuDZ

I have noticed that. Must be one of those benefits us in the IS dept have since we are always connected.

DSL at home adds to that equation too

How did you installed the 2001 variable muffler?
direct fit or some mods? Any noticable gains? cost?
thanx.

Ralmada

No, I did a little mod, as it didn’t exactly "get" on the space on the fender.
I keep the right backpressure, and noise, doubling the exhaust volume when you need it.- I did notice a slight difference in power, but the major advantage was with the sound, as in WOT, the original muffler sounded like a bad vacuum cleaner (hissed a lot). I expect to have still a greater difference with the Y pipe. I don’t know the cost, as a friend gave it to me when he changed the muffler of his max 2001

HAHAHA
you guys are hilarious
