Exhaust Cutouts and Custom Tips!!!

Definitive · 07-30-2010, 02:42 PM

I posted some of this in my build thread but never built a thread just for the exhaust. Below are some pictures of the installation.

The cutouts are Race Ready. The actual cutouts seem to be really strong. The other pieces that came with the kit, not so much. We had to re-fabricate most of what was needed to set it up. I did the wiring install myself. There were some tricks to get it to work right. But its flawless!!!

Install

Here is a sound clip from the day of the installation.

[u2b]<object width="640" height="385"><param name="movie" value="http://www.youtube.com/v/vvzsU26p2vY&hl=en_US&fs=1&"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/vvzsU26p2vY&hl=en_US&fs=1&" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="640" height="385"></embed></object>[/u2b]

The switch.

Here is a video of the switch in action.

And last but not least, here is a video of the car on a dyno, opened and closed. Not much HP difference, but at least Im not losing HP.

And a driving video open and closed. I didnt go up past 5k in this one...

wow thats absolutely awesome. The welds are super clean and im digging the black tips.
Wheels look great too BTW

LateBraking · 07-30-2010, 03:16 PM

Such a clean job! If you don't mind me asking, what shop did the fab work, and where in SoCal are they?

Definitive · 07-30-2010, 03:26 PM

Thanks! It came out way better than I ever expected!

It was actually a hod rod shop here in Camarillo. Goodfellas Hod Rods.

Came out way better than any other cutouts I've seen too!

Props to all that legit custom fab work.

That's amazing, very clean install!

Get rid of those cats and I'm sure you'll see some nice gains!!

Agreed. More info on how to do that style button would be awesome.

tightie · 07-30-2010, 04:27 PM

wow.. good job man..
those switches are the best part

Definitive · 07-30-2010, 04:38 PM

Thanks again.

I could write up a breakdown of the switch build but it was not simple and I dont have many pictures of the process, just what you see here.

I went though my first PC board experimenting and then was successful with the second one. At this point you would have to use the Race ready system, or source the exact switch for it to work.

Whats funny is that the switch they use is an old OEM BMW window switch. I could defiantly help someone trying to do this exact thing. But with a different switch would come more experimentation.

I am more than willing to help anyone local with this solution.

KiokenM3 · 07-30-2010, 04:57 PM

congrats. just wondering if i did this with my supercharger, would i lose any hp when the cutouts are open or should i gain?

Definitive · 07-30-2010, 05:13 PM

You should gain. We dynoed at a place that specializes in supercharging vettes. The owner has cutouts on his car. takes it from like 750HP closed to 800+ open. From what he says.

1. Very clean install - exhaust and switch. Had I not gone with the V. exhaust this was my exact plan - cut outs and black tips. Thanks for all the pics, documentation and dyno run!

2. It is not all all surprising to see such small gains on the dynao. The OEM exhaust is very well optimized from a major OEM supplier. They don't leave much on the table. Of course other systems will leave a lot more on the table to be gained by cut outs.

jml · 07-30-2010, 10:31 PM

Perfection, I wish my cutout install was that clean.

ium3 · 08-01-2010, 11:35 AM

Sounds awesome, do you mind telling me where you got the cut outs from? Thanks

sehrgut · 08-01-2010, 06:13 PM

Definitive - you're the man dude for this legit finnished project!!!!

kaykay · 08-01-2010, 06:47 PM

Clean install!

Love the switch, super stealthy look.

lm1z · 08-01-2010, 06:53 PM

well done!

xsilvor · 08-02-2010, 08:31 AM

Agreed on the switch - nothing beats a clean install. Well done!

Read the original post, "Race Ready" is the brand then use google...
