I'm shopping for a catback exhaust and noticed that FI now has an "Ultimate Power" version of the regular FI exhaust.

https://x-ph.com/fi-exhaust-for-toy... TIP70114S*2 + CAB-BT2B + ACT-BN&gad_source=1

The ultimate version has larger 89mm piping. I can't find any sound clips for it and was wondering how the larger diameter pipes effect the sound. I was set on buying the FI exhaust based on the countless exhaust videos I've watched but came across this and now not sure which one to get. I want something louder than stock but not obnoxious. Would the larger pipes make it significantly louder?

They do have soundclips on their YouTube channel and it is slightly louder with the larger piping but remember its still dual valved so should be quite in normal. Don't know if you should be mindful with aftermarket exhaust being carb legal blah blah bullshit in your state tho

Do you have a link? The only video I saw was with a catless downpipe.

Then we probably saw the same vid i think the only have 2 vids about it but they pretty much test all their exhausts with their catless dp very few of their vids they give us a supra sound test with stock dp

Also curious if they have a stainless steel vs titanium sound clip.

Are there any updates on this exhaust would love to hear other sound clips besides what fi puts out, especially with stock/catted dp.

I’ve been slacking on posting about it, here’s an install pic. Now that it’s been on for a couple thousand miles I’ll take some sound clips too.

Is cold start up the same or louder than stock?
In normal mode it's not much different than stock, it's pretty tame with both valves closed. Starting in sport is louder since it seems like you can open at least one valve on cold start which is different than the stock catback. My car has been tuned and catless for a while though (doesn't do the higher rpm cat converter cycle) so my comparison is probably not the best. I'll try and do start up videos as well.

Hello ! Exhaust looks beautiful, do you have any sound clips? I’ve been looking into getting this particular one, but not to many sound clips on youtube. Thank you !
