I got the Sikky Headers installed.... removed the cats and resonatory... Got the chip on the ECU to fool the car to thinking I have Cats. I am running true duel exhaust to the back of the car. I wanted to insure max horsepower so I installed Flowmaster 40 series with 2 chambers. Car runs well, but damn it loud. Especially driving down the highway in 8 gear. I am willing to put on quiter mufflers for exchange for some horsepower. I do not want to put the ISF tubs back on.... Does anyone have a recommendation for some conventional mufflers that would fit and quiet the car somewhat?

Thanks

Wes

So you used the stock mufflers. I have gotten rid of them. Looking for a bolt on aftermarket muffler. I was sure if the IS350 muffle would work on it or not.... Just searching for ideas.

Thanks,
