electric exhaust cutouts?
Hey guys....
Just thinking about doing an electric cutout on my exhaust system. Couple of questions...
1) Does anyone here with a C32/srt6 have electric cutouts on their car?
2) Many C32 owners on mbworld have tried many exhaust setups and have seen minimal to no power gains. Anyone attempt electric cutouts here (srt6 or c32)?
3) Should I expect to see gains by doing this?
I also have VRP Headers coming so that should help increase exhaust flow as well and maybe see more gains. But if I'm not going to see any gains (besides noise), I'm not sure I want to do it.

Re: electric exhaust cutouts?
I have DMH low profile cutouts that were made for the GTO. I have not been able to test them at the track, but it's on my list to do. Currently they are blocked off and need to bee sent back because they were leaking.(3 year warranty). I really hated the sound of them, open V6 just sounds horrible. I could feel a definite loss on low end torque and top end seemed to be stronger. Sadly our track has been closed for a while now and might never open, so who knows when I will get some real 1/4 mile data. Rob says they are good for some power on his car and 1-2mph in the 1/4.

SRTpowa, you dont have any sound clips by any chance, do you? what size cutout did you go with?do you feel that that gain on top end is worth the loss in bottom end? do you have the same setup as rob?

and yes you are right, i am ALWAYS looking for some new power adding mod....its just the environment i'm in. constant competition with some good buddies at the track (and in Mexico) with crazy swaps (like my roommates) and fast fast cars (like my buddy's supra trapping 135) and total sleeper (like my buddy's turbo'd g35) and the such.....always trying to find that little bit of extra to give me an edge. Nitrous is coming soon too.....lol. Hopefully by summer.

Re: electric exhaust cutouts?
i know that the lost backpressure is the biggest hassle and debate over e-cutouts.
would it be possible to do a minimal cutout, where, when open would not completely divert all exhaust through the cutout, but rather only a partial pressure release... if possible, couldn't this also be engineered for optimum backpressure on the SRT6/C32...
just a thought.

are these post y pipe or pre y-pipe (not sure if srt exhaust is the same as c32)?
any sound clips?
Re: electric exhaust cutouts?
here's one of rob's car with the cutouts open.

There is some math involved in this one, and I'm not about to start tackling that project........yet
