Hey Guys & Girls,

I just got back from the muffler shop, where I had my Tanabe Medallion Touring exhaust bolted up (special thanks to Luis at Carson for hookin us up with the GB). The set up looks and sounds great; I just had one question about removing the resonator. If the resonator is removed will my car still pass an annual emissions test? I am sure that removing the resonator is a pretty common occurrence for those of us with upgraded exhaust systems; I just don’t know how many of you live in an area where a vehicle must pass a smog test or an emissions inspection before registering or renewing it.

I am now going to go give my left arm to fill up, and then may cruise around some…
Thanks in advance for your input.

 

You'll still pass. The resonators are there to quiet down the exhaust. Think of them as mufflers.

 

this is true but the one thing you want to be careful of when removing the resonators is droning or in-cabin resonation. so do this mod at your own risk and with no benefits other than sound...you will get no increase in power from it as the resonator does not restrict any flow. if you want a little more power remove the 2ndary cats and/or get race cats but if you comppletely remove the 2ndary cats you prob wont pass smog...

 

For our 2nd Gen GS, our cats are not even close to bein restrictive. They are the most free-flowing cat I have ever seen for a stock car. I'm going to remove my resonator soon because my Borla exhaust itself is too quiet. Can't wait!

 

thanks a lot guys, ill leave it as is for now, since there is no power gained from this mod. obviously, it will be a diff. story if i go with FI though

 

My pass side pipe between the cat and the front resonator is leaking (rust from the heat shield clamps) and I need to repair, was thinking of taking out the pipe and front resonator, just not sure just yet.

 

whats going on im from brooklyn, I have a Lexus is 250 2008. I want to get my resonator and muffler delete. Will it effect my car in any type of way? Also do anyone know where i can get it done at in New York City? Comment some suggestions please.thanks

 

This is the 2GS section, try the IS section and someone should be able to help. Good luck
