I recently replaced the original mufflers with the twister mufflers. These have a similar sound to the cherry bombmuffler but are shorter and fit perfectly in the same place as the originals did.Agian the sound is a very deep agressive sound.
I'm an LS1 owner. I am looking for other things to do for more torque and top end results. I'm going to the track tommorow for the grudge runs and already have an 02 vette that wants to follow me down the track. Any idea's. So far I have the exhaust and a K&N CAI that i have wrapped with header wrap to keep the hot air from the radiator off of it. I added the NGK iridium plugs also. Not much of a budget right now. I just moved from washington state to north carolina.
awesome sounding exhaust
