Looking at adding an electric exhaust cutout to my car, but also the real possibility of cutting up a complete Borla Hush 140053 3 inch catback system to replace my current exhaust setup, with the help of some extra tubing.
The motor ingesting/expelling the gases is as follows:
4g63t, Cyclone, HKS 264/272, EVO3 stock boost to maybe 18 psi, complete to the rear bumper exhaust (2.5 inch press bent, catalytic equipped).
Muffler is currently a rather forlorn, Magnaflow offset in/out unit, faces left to right. It has seen better days and will be replaced with this unit: Borla 3 inch Hush twin tip (cut off tips and weld in L's, single 3 inch in, dual 3 inch out)
Thinking about adding an electric cutout just after my rear axle. Allows for a switch to open the exhaust just before it enters the muffler. I can even add a pipe to the cutout, to direct all bypassed exhaust out past the rear bumper, to keep fumes from getting in through the rear compartment. Torn on whether a cutout should even be at the back, or closer to the front, so that the spent exhaust, see's none of the stock system, and exits outside/under the vehicle as soon as possible. This modification is a straight line, track use type of thing. /ubbthreads/images/graemlins/devil.gif
So, possible scenario's:
2.5" system to over axle - Hush 3" muffler - no cutout bypass
2.5" system to over axle - electric cutout bypass - Hush 3" muffler
I am not a fan of drone, so leaning away from the complete 3" system. Can I expect to see any gains with a cut-out just after the rear axle, bypassing the muffler?
Got a line on an electric cut-out, just unsure at this point.
Anyone install one in a similar spot or close to the downpipe for side exit?
Here are some pics of what is on the table.
Pics are not mine, but help to illustrate where I want the electric cutout.
You can see above (last pic) that just before the muffler is the perfect spot to weld on a pipe before the exhaust takes the bend. Can be made super stealthy with a downturn tip painted black, to not show just at the lip of the rear bumper. /ubbthreads/images/graemlins/devil.gif
