okay well lets start off with this. I have a 93 GXE and i wanted to know what is the top 3 best exhost set up i can do on my car...dos it take a Y-Pipe and such please let me know sson i want this in before the summer

 

WSP Mandrel Y

High flow cat

GReddy (It's the 'best' but it's not needed...mandrel bent b-pipe will give you the same hp...you just dont get the full on quality/looks/sound)

 

I second that motion...

WSP CAI / WSP Y / CATCO highflow cat/WSP B-pipe / stock muffler.

 

James, you been looking at my homepage again?
But yes, dats the ticket for me too. WSP stainless mandrel bent Y, CarSound cat and Greddy SP. I would do things in a different order if I was to do it again. (And I might on my 5th gen) Do the Y-pipe first. Makes the biggest difference. I did the Greddy first on my 3rd gen. Hardly does squat by itself. Not the result you're looking for after shelling out $600 for one of them. Y pipe and cat makes much bigger difference than a cat-back alone and costs less than a Greddy. Cat-backs are kinda the dressing. Looks and noise, mostly. The Y is where it's at for an NA V6 car.

 

sorry for the stupid question but search is not working, what exactly is the B-pipe is it inbetween the cat and muffler or what?

 

Yep... you got it...

But if you really want the best setup get a test pipe from WSP. It's about $35 and just keep your stock cat and bolt it on everytime you have to do emissions.

 

so the test pipe replaces the cat?

 

aka straight pipe

 

Yep, like the hi-flow cats, it's a very small gain. But, if you're really serious about performance, it's the way to go.




Plus it's way cheaper.

 

Narly, thanks a lot guys

 

Here we go again forsaking emissions for very little improvement in horse power. Two things I have to say about this. In almost all cases it is illegal and secondly the Cat is there for a reason. Take a look at Mexico city and you will see in a country that has practially no emmissions laws the city has some of the worst air quality in the world. The gains in power is not worth a fix it ticket or the pollution it is going to produce.

 

you took the words out of my mouth. But don't forget to ad that if you take away all the restriction you loose power! Go ahead and get a high flow cat or keep the stock one.

 

is the warpspeed y not emissions legal?

 

From what I understand (correct me if I am wrong) all y pipes that remove precats (like those we have) are illegal. You'll still be able to pass emissions. It's not like a cop is gonna crawl under your car and say "well it looks like you replaced your y pipe which is illegal." I haven't really heard of anyone getting in trouble for having one, but technically it's not legal.

-payne-

 

If you have a 3rd gen (non ca emmission) then you DONT have pre cats so, the answer is no they are not emmission illegal. Now, if you have a 4th or 5th gen then that is a different story.

 

you dont loose power from a test pipe but just low end grunt but you gain power past 3k and i passed emisions in MO with a y pipe and test pipe so i think our cars are pretty clean running cars

 

okay good cuz i wasnt quite sure what the precat looked like. im in az but i have had to deal with so much sht even on my old 80's volvo when it came to emissions so just wanted to clarify thanks

 

Dang, am I understanding that if I get the warpspeed y pipe I will be getting rid of the pre cat? Didn't even know our cars had a dang pre cat. This sucks since I live in the great state of California (it was great till Davis bent us over backwards and screwed us into a big pile of debt...) Is it true that by getting a new y pipe I will be getting rid of the pre cat and thus out of reg with California?

 

Ahh....NO 3-gens have precats, ca spec or otherwise.

 

I agree with Adamis. Think of all the extra pollutants you're pumping into the air by removing your catalytic. It's there to burn the unburnt hydrocarbons that don't fully ignite in your engine. You might say "How much damage can be done from just my car alone", well if a couple hundred thousand people in North America have the same attitude as that, it causes a big pollution problem. Be responsible and do it the legal way.

 

Mine doesn't and never did!
