I'm knee deep in my winter project/ upgrade/ repair, & just general maintenance...I've decided to remove the silent choice & replace my Corsa baffled tips with straight tips with flappers. I'm running a 454 mag mpi, will this effect anything by eliminating the back pressure that the Corsa tips provided? Or will the computer adjust for this? Will I notice any performance gains? Or is this just a waste of time to replace the shiny stuff?...

It should not hurt anything. You wont notice any big difference in power or speed. Sometimes you gain no extra power or speed and other times you can gain 1-3mph at best depending on how choked up the stock set up was.. If you already had thru hull it probably wont be very different from where you were already, but on occassion ther are some small suprises.. If you do swap the tips It will however sound much meaner & cooler.. Jamie / Lakeside

Like Jamie said - the sound is the biggest differnce. It will sound bad azz. You may get a little more midrange punch - maybe.

If your Corsa tips have the dual baffles, they are pretty restrictive. You may see 50-100 RPM increase at WOT. I recently dyno'd a 496 and we installed a set of single baffles to test. They cost 10 HP over no baffles.

You guys seem on track too.. I would figure mainly no difference in bottom end. Mid & Top only maybe a little depending on set up & overall application.. But it shouldnt hurt it & It should sound cool... Jamie / Lakeside

Thanks for the input, I was actually suprised to see that the baffles were fixed, & looking at them, they do seem quite restrictive. I am looking forward to the better sound, & whatever, if any, gain will just be a bonus....

The tips are restrictive and you should gain some power with straight tips. The merc computer does not adjust itself to conditions other than the knock meter. It has a fixed fuel and timing curve.
