Hey guys had a question for ya. Someone gave me the idea of putting 2 cutouts on my car on the Ypipe (one on each side) I would get the sound that I want and also be able to cover them when emissions time comes around .Also if I got an electric on and saw a cop or whatever i could flip the swich and sond goes away and no pull over by mr police man. Is this a dumb idea or could it work?? and...

my questions are
1. How far down from the O2 sensors will i need to go?
2.Price on an elctric cutout. I might consider a used if it works but does anyone know what combo sells them for??

 

Why two? You'll get a great sound with one cutout after the Y.

If you go with one, put it right after the Y. If you still have your heart set on two, run an approximately 6" (or longer) extension after the header.

Prices and quality vary....do a search on CZ28 and you'll find plenty of threads about a few different types.

 

I'd prefer 2 as well, but remember, with the electric, there's twice the cost and 2x's the stuff to break Electric cut outs are prone to failure.

I'm still gonna og with one 'cause I ain't crawling under the damned car everytime I want to hear it!

 

don't do it. if ur gunna put in a cutout in do it in the I-pipe.
by the way this is straight from the mouth of an exhaust specialist because i had the same idea.when you have ur exhaust coming out of ur y-pipe it is hella bad for your car. you are losing a huge amount of torque cuz there will be no backpressure. also it will *pop* like crazy and occasionally suck in cold air back into the heads which will warp the **** out of ur valves.

 

Might want to do a little reading on the whole "backpressure" issue.

Also, you aren't going to see any outside air sucking all the way up the header and into the head....just isn't going to happen. The exhaust pulses are FAR too rapid to even think that outside air is going to go all the way back up from the y-pipe and through the headers or manifold and into the heads, I'd probably have a better chance of a purple dick growing out of my forehead than that happening.

I really don't mean to sound like a dink but it's the spread of so many internet fallacies that perpetuate these myths....I heard someone say that backpressure absolutely destroys your torque so it must be true. As I said, might want to do some reading on that or kindly post up some hard facts to prove me wrong.

 

only thing i dont like about putting one on the I pipe is that the cat is right there and I would have to move it. Plus If they are on the Y pipe all i have to do is close them and it goes to stock sound and emissions. Ie.I wouldnt have to move or even worse take off cat.
Dont know if it is a totaly stupid idea but if it is something I can do and it wont hurt my car then im on it.

Just wondering

 

haha.. Neil needs to read this so he can give me his cutout... lol

 

put the cutout on the I-pipe beneath the rear axle or just a little before it.
and the whole backpressure and valve warping thing i heard from an experienced car guy who has had his exhaust business for 20 some odd years. He has had experience with fbodys and people trying to do this. If you want max power then you should just run strait pipes.
oh and ghostz you might want to contact your local purple dick remover and get that checked out

 

Nope.....Mr. Muffler apparently doesn't know what he's talking about. Do you realize that you have four separate exhaust pulses per revolution and at 2000RPM's you're seeing 8000 pulses per minute which is 133 per second...please tell me how outside air is going to get from the end of the header, travel back up the exhaust tract the four or more feet in order to hit the valves?

That's right....it's not going to. Sure it can travel the short distance between the end of the header and the O2 sensor due to negative pressure but making it back up to an exhaust valve....don't think so.

And as far as backpressure, here's a little read for you:

As I said....post up some hard facts aside from what some guy at the local muffler shop said once over coffee.

 

Humm so does this mean its a bad idea or good LOL

Heres my story...I had an exhaust problem ( well i thought i did) So what I did was I un bolted the exhaust pipes where they are bolted at right under the O2s. I started it up and drove down the street(to find out if a clogged exhaust was the problem I have been having with my car) Well it turns out that an exhaust clog is only part of my problem. So I bolted the pipes back on. While they were off the car sounded freaking awsome of course. The whole reason I asked about the dual cutouts is because I want that sound but I dont want to take my cat off and I dont want to spend a ton of money so it seemed like a pretty good way to go. That way at any point I can flip the switch and they are quiet and emmissions legal.

Thanks for all the imput hope to have this figured out soon hehe

 

I would run dual cutouts but that's just me. Like was said before....that's twice the money and twice the problems since electric cutouts have a tendency to fail.
