**98T/A.SNAKEATER_** · 10-07-2008, 04:45 PM

just bought my first trans am and im about to do the exhaust... hooker headers and 3 inch all the way back but ive heard about cutouts but not sure exactly wut they are?? could somebody fill me in?

They are a y pipe you add behind the headers. They have a cap that you can take off to run open headers. Or cap them to run through your exhaust out the back.
Here's a link for some on ebay !!!

^^^General idea, but bad description. haha

It's a y-ed section of pipe you weld onto your exhaust. It essentially dumps your exhaust when it is uncapped, and when capped the exhaust runs like normal through the muffler, bullet, or whatever you have. Some people put two cutouts in right behind the collectors, and others put one cutout in their i-pipe.

I'd go with an electric cutout...very handy!

when I was on stock manifolds and cats I was the same way. I would've never bought a catback if I had done that mod first.

quick question whould i need 2 or 1 cut out i got lts ory and full 3" cat back..

for track use!

**0rion** · 10-09-2008, 09:10 PM

I would ( and did) just do one under the rear passenger seat area. There's a grommet there to run wires if you go with an e-cutout at some point.

**Adam_WS6_** · 10-09-2008, 11:50 PM

so just one? and and were was that grommet excaltly located at i was gonna go with the e-cutout. do you know/have any pics on that?

**NorthwoodDavid** · 10-10-2008, 07:31 AM

that grommet is right above that position pretty much. You can see it if you look under the car. I pulled the passenger seat out and ran the wires under the carpet and up to the front of the console. Then I ran the power wire over to the fuse box and used a quarter inch spade connector and plugged it into an aux. spot in the fuse box.

Ive been looking into these for a while. Ive got the true-dual exhaust on the GTO, and was thinking I should go with a pair of these right after the headers. Problem is, it seems my cats are bolted straight to the headers, and I wanted to bypass them. Any suggestions on how to splice in the e-cutouts and retain the ability to pass inspection?

**0rion** · 10-10-2008, 09:24 AM

So you're running headers with catted mids? I personally would put them a little further down stream than right off the headers. I would put them just behind you in the catback portion of the exhaust.

**devil6rr** · 10-10-2008, 09:47 AM

sounds like this !

**PatrizioD** · 10-10-2008, 10:29 AM

Im running completely stock right now. Not trying to hijack the thread at all, so Ill try to keep this beneficial to the OP...

Im thinking about grabbing some black-coated Pacesetter LT's eventually, but was gonna put the cutouts on first (sounds like a bad idea now that I typed it out...)

So I guess I should order the LT's and cutouts at the same time, and have them installed together. Cutouts sound soo badass. I think i'll go for the electrics.

On a mostly stock car (and most cammed cars) I do NOT recommend dual cutouts.

There are some instances that will gain power, but for most cars it will lose some.

not the OP but patrizioD has a gto....true duals. If I were putting cutouts on my gto they would be in the catback just after the mid-catback connection.

So dual cut-outs could lose power?

Yes.

**PatrizioD** · 10-13-2008, 05:19 PM

Ok, so which side do i put the cutout on? Wont it cause a lopsided pressure buildup in the headers? I mean if one side goes through mufflers and one doesnt, wont the muffler side be more restricted?
