List Some Quieter Mufflers...

I've got a bigger engine then you guys and have a 3" turbo back into a flowmaster delta flow. That's pretty quiet. I'm pretty sure flowmaster makes a series designed for "sport compacts" also, AKA you small engines guys :whipped:

What does that truck engine need a high flow muffler for? It's not like you are going to make any power with it! :stick:

You could keep what you have and add a resonator...

I have 3" downpipe to Thermal 3" catback whick has a can (huge) and a 5"tip, its is just low. Its only really loud at full throttle in upper rpms.

The silencer idea works good too, my friends gf puts the silencer in whenever she drives long distances and it helps alot, tho her car is non turbo.
