I actually quite like the sound atm with the small rasp. So removing my cats wouldn't be the way I should go? |

The easy way to explain it would be you can hear the difference between shifting at 5, 6, and 7k. Before, the rasp would mute any tone so you couldn't really tell the difference at the higher rpms. Worthwhile mod in my opinion. Totally changes the dynamic. Something was missing in the sound with the secondaries still on and the vibrant resonators fixed that issue.

But in terms of actual Db increase, will it make the whole system louder? You said your pops were louder right? Last edited by TheMidnightNarwhal; 10-17-2018 at 06:52 AM.. |

I'm either doing second cat delete with resonators + X pipe or get a VRSF cat back. I think the first option would be optimal correct since IS already has a sporty muffler? Can't wait to hear it. Do you have any videos of your sounds by chance? |

H pipe will give you deeper sound. X pipe will give you more HP. |

I'll start with the resonators and we will see how it sounds. I might take a peak and compare inside my muffler box with OEM exhaust mod see how it looks inside and might make them straight pipe in there (if they are not already). |

New exhaust tips and second cat delete. I was wondering do you have the OE exhaust mod? I was considering removing all perforations but I think it might be loud. Would like to remove perforation only on one side of the exhaust and have the valve controlled by me (so less loud mornings starts) but I read that's not good. You 3 feet of SS pipe only has to be straight, not a curved one? In the picture it seems like the gap of a straight one would be to wide for welding? |

There isn't an up side from performance standpoint to modifying your muffler... I removed the secondary cats and the exhaust was extremely loud. Cold starts with the flap closed didn't help. I imagine that will be similar to your setup as the 1792's don't muffle much, but will certain help with the rasp.
