I know exhaust threads have been exhausted but I am experimenting on mine to get it quieter and am curious what you guys think. I bought the car with this installed: PCD, Endless J pipe, XLR8 high flow cat, resonated Endless rpm catback exhaust. I enjoy the exhaust sound but the drone has been killing me with all the hills I have to drive up to work at 2500 rpm. I removed the 6"OD x 14" long magnaflow resonator and replaced it with a 4.5"OD x 22" long magnaflow resonator (10436). It did not change it at all really. Has anyone put another resonator where the mid muffler used to be in and have two resonators with aftermarket (magnaflow) mufflers? I am thinking of placing the 14" one in that spot but am not sure if it will make a difference. Is there a high flow mid muffler that people have installed?

I would try removing the pre cat deletes and putting stock cats on to quiet the exhaust down...from what I read in multiple forum posts, most people are wanting their exhaust louder that that is commonly recommended. Hope that helps.

I agree with Matt, removing the pre-cat deletes should quiet things down a fair amount; but you will lose power with the stock cats.

You could try adding something like a Vibrant Ultra Quiet resonator to the mix (Vibrant Exhaust Fabrication - Ultra Quiet Resonators UNIVERSAL - Excelerate's Honda & Acura Store - Japanese Performance Specialist), but I'm not sure if that will be enough since sound is a preference based thing.

If you need help finding something or would like a quote feel free to send me a PM!

Good luck & happy modding!

So do you think adding the second magnaflow 14" resonator will do anything?
