I had my resonator replaced with a section of straight pipe (the rest of the exhaust is stock). The job took 15 mins and cost $40. I start it - sounds as quiet as stock. I drive a few miles - 98% as quiet as stock. I take her out the hwy - still very quiet (zero interior resonance). Up to 4K RPM this mod sounds so close to a stock it's actually sad. Above 4K RPM it's a bit louder but it doesn't sound good. IMO this mod is a total waste of time and money! Now I'll have to have the stock Ford resonator welded back in and get a Magnaflow.
