Walker 17843 SoundFX Universal Muffler
This is what I put on my car last year. Sounds old school and quite inside the car. I also have a crossover pipe, my tips extend beyond the bumper.
I just swapped the mufflers on my car. Went with Walker Sound FX with an 18" body replaced the Summit Racing turbos with 14" body. The harshness in the passenger compartment has been reduced greatly and the exhaust tone is still nice.
