it looks like removing them drains power, the BC test shows -6HP and -10 lb-ft TQ, that was only brought back close to stock by adding the CAI....they failed to really complete the test by running it with the silencers and the CAI combined.
But in theory if you leave them in and add the CAI that test suggest you would be +5HP and +5 lb-ft TQ; add in a tune and you are probably getting even more out of it.
either way...my original question still stands; does anyone have a set the pulled out of their Expy that they’re willing to part way with for a reasonable price?
