A y-pipe necessary?

A y-pipe necessary?
I have been seriously considering purchasing a y-pipe for a while but am concerned about a few things ..... yes I am a noob. First off, my car savy co-worker says it is a waste of money because your headers and cat-back are still stock so air flow won't increase. My second question is emissions. I have read in some posts that you will fail emissions and others that you have to warm up your car first before you do emissions. My third is what Y-pipe does everyone recommend. I was probably going to do cattman cause they are very prevalent.
So to sum everything up ... should a y-pipe go on my stock 95 GLE with the exception of an intake that is going in this weekend and how much can I expect out of it.

it eliminates the precats (before the cat fires up) so you will only fail emissions if your car is cold.
Y-pipe was my first mod and it was one of my favorites. its third next to my supergcharger and vb.
i would totally recomment it, your butt dyno will feel it instantaneously.

"it eliminates the precats (before the cat fires up) so you will only fail emissions if your car is cold." slimer
OK, but what if your state (Ohio) doesn't do the normal tailpipe testing, etc. and only hooks something up to your car computer and gets info of it?
I just had an emissions test done two weeks ago and they didn't put my car on the rollers and rev test it, etc., they just hooked some wires under my dash and viola, I was done in 1 minute. I guess they only do it that way for 1998 and newer cars.
I was happy, but would a Y pipe affect this type testing?

Cool.
Can you have a Y pipe installed by a muffler shop or performance shop? Or do you HAVE to install it yourself? I certainly don't have the tools/knowledge to do it. Plus, I'm afraid I'd **** it up.

Yeah, I figured you could, but I've seen posts where they said shops won't do it because is affects emissions, etc. Maybe that's just CA stuff?
Seems to me if you can buy a Y-pipe for $200 or less and get it installed for $200 it is kind of a no brainer mod imho. Even if I did nothing else, I should at least do this.

Go with the new superflo y-pipe from warpspeed. It does not have a flex section so "no bees in the can" is guaranteed. It has these springs instead that do allow the y-pipe to flex in the area of the "flex section" so it's perfect IMO. I will get it soon:

I got a budget y. No bees in can sound, no fit problems. inexpensive and stainless. I have the budget B pipe with resonator too but hooked to stock muffler for now. pre cats are the choke point for sure.. I honestly cant see spending more cash for basically the same thing. Its not like it is a visual piece, if it works without problems why spend the extra cash? Just so you can say "I have (xxx) brand"? Not saying they dont work well or that they are junk, very good stuff from what I hear but for the price of the y from other companies you could get the y and b in stainless.

first of all when ever you go into a emissions lane, your car should be warmed up, your car is in open loop so your o2 sensors wont be up in running until it gets to about 600 degrees. your car will run rich on start up, and when the car gets warmed up, the car will lean it self out. i have a wsp y-pipe and it does its job, little rattling, but it was the exhaust hanger.
#19
I apologize for teh simplicity of my question, but in reference to the emissions test, when y'all say "warmed up", do you mean just that the ignition's been fired up for 10 or 15 minutes or that you've driven around for a couple hours? Also, what if you bring your car to the inspection place and it takes a while before they do the test?

If the budget stainless steel ypipe is just as good as cattman's, why do people praise cattman's ypipe? there should be a reason for this right? or is everyone just thinking "you get what you pay for" without any proff of which one is better than the other? because cattman's ypipe is a lot more expensive!
#23
I honestly don't know anything about Cattman's Y. It could be very possible that people assume that they get what they pay for, and think that for 200 bucks, something must be cheap about the pipe. So far, I haven't heard any negative feedback on Budget or Cattman, so I would buy whatever is going to save me money if I can get the same performance.

yeah, that is true, because i had the warpspeed ypipe, and i have no idea on how many times that ypipe have given me cracks, and i had to re-weld it together and had my flexible pipe busted once also. but at the same time, it wasn't stainless steel. ill give budget a try. i think its worth it.

i have a question regarding backpressure when adding a Y-pipe while keeping everything else stock
will i have abnormal backpressure which might affect exhaust flow out of the engine.......and also do aftermarket Y-pipes use larger diameter piping compared to stock?

#26
I believe it's more like they're the same diameter in piping, but it's more bored out so more flow. What restricted the flow was the pre-cats but with the y-pipe it eliminates that problem and gives higher flow to the muffler, thus being able to push more power (hp/torque)
#27
Massachusetts just passed a "more strict emissions" law or somethin not too long ago,and since then,I've gotten inspected with a y-pipe all the way back and passed.I'm sure you'd pass with just a y-pipe if I did in MA.
#28
So to answer my own question ... a y-pipe will add even if I don't upgrade the rest of the exhaust system. Also .... where is the B-Pipe ... before or after the cat? The thought of a 200 dollar mod + 200 installation is killer. My debit card isn't too friendly to things over 125.
#29
b-pipe is from cat-muffler (not including the cat or muffler).And yes it'll add some power without the rest of the system.
$200 mod,but if you do it yourself,all you need is a jack,jack stands,pry bar,14mm socket i think,and a few hours later you should be all set.You're in GA so there shouldnt be too much rust on the bolts.
