Anyone Running Full Catless w/Muffler Delete? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

djliquidsteele · 04-25-2013, 04:03 PM

Just curious if anyone is running this setup. I am currently catless with muffler delete from the header back. I really like the sound and am just wondering how much louder it is going to get without the cat in the header when I buy headers.

Thanks

If it doesn't bother you now, odds are you are deaf and its probably not going to matter anymore once you do the header. My car is loud with the stock front pipe and SRT catback at WOT, maybe not illegal for track use loud, but loud enough.

I can't even imagine how loud your car must be. lol you should just a big vinyl that says pull me over on the side of the car

I live in Kentucky where hot rods and big muscle cars are the norm. We have no laws about how loud a car can and cannot be. And at WOT over 4k rpm, it gets pretty quiet. Almost stock quiet. Its only about 90db inside the car.

Stock exhaust is in the low 70s dB range OUTSIDE the car.

I'm cool with it. To each there own, right? I think it sounds great, others have said so too.

I love my exhaust set up im currently running borla uel headers catless perrin front pipe stock midpipe and berk muffler delete single tip exhaust. I dont usually have an issue with loudless as long as I drive through neighborhoods conservably which isnt very hard to do but it deffinitely turns heads in a positive way and was told at the track my car sounded like a wrx driving down to the starting line. Just an all around great agressive boxer rumble that can get loud really quickly but sounds bad ass regardless.

I have this set up, I just haven't tried it. I'd imagine it's pretty loud. Similar to a race car. Probably sounds great around 5k rpms but it probably gets old.

I can't say for my FR-S, but i've got, basically, straight pipe(no cats) on my Triumph Daytona 675. It does sound great when i'm in the mood for hooning around at 13k rpm or at the drag strip, but cruising down I5 at 75mph for an hour get a little tiresome.

Basically if you doesn't bother you then go for it, but it will certainly be loud.

Ok, so after this I went and tested again. its actually 68db inside the car at idle. Its 90 db inside the car at 80mph.

So at 4K RPM cruising or 4K RPM WOT it's 90dB?

At about 3500 cruising. It actually gets quieter as it moves up the rpm range. I'd have to go check, but I don't think it ever gets about 93db inside the car going from 2k to 8k in second with Visconti tune.

You might want to put in a big resonator somewhere to kill the rasp. With a header an no cats at all it'll be REALLY raspy.

ftc~brz · 04-26-2013, 06:13 PM

It's borderline painful at higher rpms. just be prepared. its a personal preference and everyones sensitivity is different.
