Can you just slip fit them into the end of the pipe? Just for a sound test? I think you’ll have enough room to just stuff it on for a sound test. Maybe not so much driving with them in though... LOL!
Well, I have turndowns. So, I'd have to cut off the turndowns and slip them on, trying to bend the exhaust below the bumper. So, I'd need new exhaust tips if the resonators don't work.
