I don't know if any of you will agree with me, but I think it is somewhat hard to make a 4cyl sound good, so I am looking for the best flowing quietest muffler around. Anyone have suggestions?

 

i have a dynamax muffler on my 4 cyl 22re and i would say its very quiet. dunno how the flow is should be better than stock, but i bought it this way so i cant compare.... anyways it isnt loud at all if thats what your looking for

 

you have to get a flowmaster muffler and K&N air filter....worlds of difference!

 

Flowmaster "50 Series Deltaflow" is the way to go IMHO. Quiet inside, deep tone outside. Sounds great on my 99' w/5VZ-FE. I'm sure it would sound nice on a 4cyl too. No droning like the 40 Series or 50 SUV. In fact I know it does cause a guy near me has one on his 22re. Cost me $80 + install.
