Was happy with the Magnaflow exhaust setup on my '14 IS so went ahead with a similar setup. I kept my previous '14 IS' OEM exhaust piping which I now had Coachworks Automotive weld the Magnaflow offset/center 4x9x11" mufflers to it and make a bolt-on axle-back. I also wanted the stock look for the tips so I had him place the OEM tips on my new exhaust.

Watch the video to listen to the setup below which includes the first phase res-delete with stock mufflers @0:21, then the final phase with the Magnaflow mufflers @0:50

Sounds tasteful! I'm always very close to buying that lip spoiler but I'm on the fence about it. Looks good!

Thanks. For the trunk spoiler I was on the fence but for 60$ it cost, it was an easy decision. So far, I like it but if and when I don't like it, well, it's just $60...

does removing the resonator affect performance at all? i was told removing the resonator reduces horsepower

Besides sound, I didn't notice any difference either way.

If you plan on just doing the resonators with the stock exhaust, I don't recommend it since the sound did not improve at all to my ears (unlike the RCF which it did).

Hi there. I actually found your YouTube video first before looking for your thread here in CL. Do you think the sound will be similar in an NX200t/300? That has one single mid-pipe, whereas your IS300 has two split ones. Thank you.

EDIT scratch that - I thought the IS200t was renamed to IS300 like how it was in the NX. Didn't realize this is still a V6. Cheers
