Of a car running straight off the cat no exhaust?

Ideally a 3sgte (st215 PERFECT!). Trying to figure out sound levels to know if I'll get in trouble for starting it in the HOA or not...

A soundclip probably wont give you much of an accurate idea of how loud it will be. I did this on my MR2 though, it sounds like a very pissed off chainsaw, and its pretty loud.

I'd imagine if you didn't let it run for a long period of time you'd be ok, but if you were to have it just sit and idle to warm up or something, it'd probably piss some people off.

I'll be starting it to bleed the radiator and make sure everything's filled/running properly...

Open the First start video in my gallery http://www.celicatech.com/gallery/browseimages.php?do=browseimages&c=3&userid=90&page=11 The video is with the midpip only. It's not too loud at idle but it does get louder as the revs go up.

I have quite a few vids of my alltrac with just an open downpipe, no exhaust.

Yeah, had open downpipe on an MR2. It was extremely loud. Yes it would likely piss your neighbors off, but if you were really gentle with the throttle while leaving the neighborhood and aren't coming and going at all hours they might let it slide.

Maybe the guys that don't think it's loud just have a lot of sound deadening in the car or already lost all their hearing?

Cool.

Not planning on driving it, just letting it idle with an occasionally rev here & there trying to settle everything in.

Well it definitely makes it hard to hear anything going on in the engine bay with the open downpipe.

When I was doing my trucks exhaust I had to make a trip to the store with just the Y pipe and cat on. It really wasn't too bad at all, the bass is more noticeable than the sound.

I wouldn't worry about it.

My car does not have a cat and its not even that loud. With a cat its hardly obnoxious fire it up.
