Exhaust tips

At that point, you're better of going to a Universal muffler that already has the tips on it, and your muffler shop will have to lengthen the stock pipe going into the muffler to bring the muffler further to the rear of the car.
This is beacause the factory tip is so long.
I'm planning on doing something similar on mine in the next two weeks, so stay tuned.
Looking at my system, it appears that there is an additional silencer in the system that can come off and a different muffler can be used.
