hey
i have is350 and i am considering to get i muffler delete
if anybody done it ,did you notice some power loss?

 

Are you trying to get a LOUD car vs. True power gains + Sound?

 

Response to OP:
No loss in power on my IS250. The drone is minimal and can be easily drowned out with music. Highest amount of drone in 2K-3K when you're hitting the gas, but when you go cruise, you can barely hear it. Everyone tells me they can hear me down the road with the muffler delete but I wanted something louder and got the resonator deleted. The car is super loud now and it drones which is noticeable. I think it sounds amazing and the drone doesn't bother me.

Response to question above: you're going to gain 3-5 hp with a $1K+ exhaust, not worth whatever you're going to mention. My muffler + resonator delete sounds just as good, if not better, than any exhaust set up I've heard on YouTube. You can't modify this car for HP unless you do that turbo build that one person is doing from Dubai / Saudi.
