get the greddy evo lol

 

The thrush turbo muffler sell them at advance auto. Has a nice low tone and still non restricting. I hate loud exhaust my cars pretty quiet with it , and im running straight pipe all motor very nice tone.

 

One of the most effective things you can do to reduce noise is add a resonator. Use three inch all the way back with one or two resonators and maybe that Thrush or a Flowmaster. If its still too loud, a Magnaflow 3 inch catalytic converter will bring the exhaust down to damn near stock noise levels but still flow plenty.

 

Thanks that's all I needed to know
