Ok, for those of you who do not know what I mean, exhaust cutout was installed today, along with a 2.5" straight pipe from the end of cat to the first 90 degree bend. As time goes on, I will be purchasing the following: a 2.5" 90* bend pipe, the first and second sections of the neon piping from bend to muffler in 2.5" then a dual outlet muffler in 2.5" also with 3" tips. Maybe 4.5" ricer tips, haven't decided j/k maybe.

BTW - I started it up without the plate on (cutout open) and this thing sounds like a BEAST! I wish I could run it open all the time because it reminds me of my old 73 Monte Carlo - such an awesome sound!!!

Anyway, pics are here -

Badass dude! You need to get a soundclip of it...damn, I knew I shoulda kept that, hahaha, j/k...looks good though!

Im confused..

Why a cut out.. then a straight exhaust?


You should run a cutout.. then on the other half BONE STOCK exhaust....

BTW: You can find the ecutouts for round $100 to bolt onto that

Cutouts are meant to go before a cat to give serious gains. Kinda pointless for anything other than sound when put after the cat.

so when u want the cutout off u have to crawl under there and unscrew the plate? seems kinda lame, u should go for an electric cutout my friend has one and its fuckin cool.

No they are not - do some more research. You can place after a cat for more gains over stock - it is like running an open header.

I am, as soon as I get the rest of the exhaust installed, I am going to get an electric attatchment for it. As for being lame, why is that? I aint going to be running it on the street... only for the track, and on those days I can get under the car and get it out.

Ok, not straight through to the rear, it will be stock, only 2.5" all the way through - the straight pipe for now was for resonator delete and begining of my exhaust. The rest comes later, when I have more moolah. And where do you find the ecutout for $100???

Looks nice man. Looking forward to hearing it next friday. Clean up the chopped up tunnel heat shield though....

Looks really good now for a soundclip. The thing i'm trying to figure out and maybe you can help me. Does it lose power when the plate is on, you would think that it would create turbulence because of the exhaust gases bouncing off the plate. Thanks in advance.

I had it on my SRT.. I loved it.

Thats a 3", I need 2.5" - but AWESOME find... I think Diablo0 is looking for one just like that. And, I will clean it up, eventually... I know, looks bad right now, but will be better next time it is up on the rack.

As for power loss, no, none, nada. Actually, since I have the larger pipe in place now, it made the sound a lot deeper. I am sure that eventually, I will get a dyno - then put on the rest of the 2.5" piping, and then will dyno again - better see a gain!

why not just use an open head, much much better flow!

Actually, if u have an R/T u could always just take the rear exhaust part off, save some weight and increase exhaust flow at the same time, and the best part about it... it's free!

i wanna put a cutout on my car too. how much did yours run you?

why not just get the one from modernperformance.com?

http://www.modernperformance.com/all/qtp_cutout.shtml

"Available in 2.25/2.5 and 3"." Plus it's only $154.99.

30$ shipped, brand new in box from here on the forsale boards - brand new anywhere else, pretty much the same, maybe a few duckets more.

As for sound clips, I will have to get some this weekend, have to use my iPod, so I do not know how well it will sound

Anyhow, I am going to get the auto openener thing-a-ma-jigger next - then comes the rest of the exhaust - I actually may just wait and get the exhaust first, as my car pulls pretty hard right now with larger diameter piping up front.

No they are not - do some more research. You can place after a cat for more gains over stock - it is like running an open header.

How can running a cutout after the cat be like running an open header? This makes no sense. A cutout before the cat is running an open header. If your exhaust is really complex and full of bends, a cutout after the cat can give small gains. However, bypassing the tightly packed emissions filter known as a catalytic converter by putting the cutout before it will give much larger top-end power gains. How do I know? Because I've done it!

Don't believe me if you must. It's your loss.

Indeed.. this is true.

AFTER the cat is just like running straight piping without a muffler.. that's all you are by passing... The cat is more restrictive though.

well, he could always move up to a high flow cat or gut his stock one...im sure then he'd see better gains...plus high flow cats are pretty cheap even with an 02 bung.

nice job man - good price

Just get an electronic now : ) and maybe gut that cat out - youll be screamin : )

Def agree.....nothing like open header. I used to build drag cars I know from real world experience....not what research on forums says.

Ok, so do you all feel better now? I stand corrected. As a matter of fact, when I can, I am going to buy a new cat and move the location of the cutout. As for the way some of you approach feedback, you really need to work on your personal skills. I never once made mention of NOT believing you, I was going off of the info that was gievn to me, and that which I had my hands on at the time. I figured I had the best I could and went with it. As for research on forums, if your real world experience is supposed to help me, but I get the info from here, then by your logic, I should disregard it. Help me out. Excuse me if I sound defensive, but if you re-read some of your posts, you can probably see why.


As for sound clip, I have one, but it DOES NOT do it any justice - it resonates really bad and the clip was not done on the BEST mic. The first part/30 seconds, is stock, second half is with cutout open.

But here it is anyway: Click here to listen to ACR-exhaust cutout

edit: at the beginning of the audio, at idle, do you here that 'rattle' sound? Any idea what that is? Is it typical neon stuff, or signs of something internal needing looked at? I have heard it for as long as I can remember.

I think its the lifters mine does it to. That mic does the sound no justice. Do you have a camcorder if so film it with that.

yeah, it sounds a bit muffled with it open...try just using a video camera and put it down at the end of your exhaust and then when you open it, put it by the cutout...still sounds beefy and mean though.

There's no need to get defensive about anything. Remember that you're the one who told me to "do more research" in the first place.

As far as re-doing your exhaust in the future, just have an exhaust shop replace your stock cat with a straight pipe and then add a smaller, high-flow unit about a foot past the cutout. If they charge you more than $100 for parts and labor, you're getting ripped off (assuming you provide the new cat).

Custom exhaust work is 99.9% likely to be cheaper than any preassembled unit and is almost always more to your liking. I have never purchased a premade exhaust setup for any of my cars and I never will.

my 2001 R/T does the same thing..... it was the first thing i noticed in your clip.... "I was like hey his does the same thing!!!"

its just the lifters as far as i can find out... I got about 155,000kms on my motor and it did it since i got it at 60,000.....



edit.... the cut out sounds mean..... we need a fly by though...
