I've been contemplating whether or not to do a res/ muffler delete. I was planning to run the invidia midpipe+HKS exhaust setup, but after hearing just the invidia midpipe alone most people said there wasn't a significant difference until the higher rpm.
Would it be a good idea to do a res/muffl delete for now until I can run the invidia+hks? I hate how quiet the is350 is. My goal is a more aggressive deep tone, especially in the lower rpm since I usually just cruise.
Nothing excessively ear-bleeding loud, but noticeable.
I went through the same exact back and forth when I was deciding on doing a res delete. I also didn't like how quiet my IS350 was and wanted a more aggressive/deep tone.
I had the HKS Hi-Power exhaust installed and noticed very little difference with the sound until higher RPMs.
I ended up doing a res delete and had the aggressive sound I was looking for. However, that did come at a price...
Deleting the resonator, especially with the HKS Hi-Power exhaust, tends to cause a lot of drone. At highway speeds or at fairly consistent speeds, usually anything that has you steady at 2500RPM or so causes a loud drone.
If you don't mind the drone, I would say go for it. But if you care about the drone, and I guarantee that if you don't most of your passengers probably will LOL, I would suggest that you find another solution to just deleting the resonator.
Have you already bought the HKS exhaust btw? What year is your IS350?
maybe try the mufflers first then go onto the resonators
