3" Straight thru exhaust?
 
straight thru exhaust? (stainless steel), with no muffler / cat / resonator? will it sound good at all?

currently all my car has is a huge muffler underneath the body (no cat)....it's the tanabe muffler or something the previous owner said, all I know is that the downpipe / midpipe is 3" stainless steel (tanabe downpipe, and a midpipe.)

how loud would it be with the muffler off, and how would it sound? does anyone have a video clip of it? thanks.

Everyone has their own tastes (sound level and character), but I know I would hate a 3" straight pipe. It would be too loud and raspy for me.

It would sound like shit and be way, way too loud.

TrevorC 03-02-06 10:06 PM

anyone have a sound clip of it? I'd like to hear what it would sound like.

everyone has different sound tastes. :)

I have three inches straight through with a streetport sounds great. That is my oppinion though lol, I got the JIC Spec 90 exhaust...

mine is street ported also.....is there anyway you could record a clip of it? idling / rev? Or is there anywhere where I can listen to exhaust sound clips kinda like the LS1 boards?

If you want an idea just take off your exhaust and run the car...It is very loud and IMHO it is not recomended

Aeka GSR 03-02-06 11:46 PM

ive got a straight through exhaust with a straight through muffler, I hate the sound, raspy and loud. I'm currently working on fitting an apexi active silencer on it for daily driving.

Prince6599 03-03-06 12:02 AM

Yeah I can set up a sound clip... I am not going to be around the car until Sunday but I will take a clip, I don't know how to host though... I dont know about the quality either... All I have is a digital camera

Wargasm 03-03-06 10:01 AM

Mine is straight but with a Racing Beat single tip muffler on the end... and it's plenty loud.

In fact, if it were a little quieter, it wouldn't be a bad thing. Keeping a low profile is worth a few HP :)

Here's a hint....undo two bolts and pull your cat-back off. Then you'll know exactly what it sounds like. I really don't get threads like this!

In my opinion it from my '91 rx7 it would be Way to loud and have backpressure problems.

sound clip would be much easier than going outside and sweating my ass off in texas heat

....if no one has a sound clip, then I guess I'll just have to experiment and goto a muffler shop & get a test pipe fitted and see if I like it.....

Ive seen a couple for sale in classified section in the past, but those were for "racing only" exhaust and definitely not for the streets. I would imagine it being light as hell w/ the cats, resonators, mufflers and etc.. Good luck.

RX7_Fanatic 03-03-06 01:20 PM

it would be too loud for a camera to actually capture the sound accurately, but trust me, its raspy, pulsy, and only kinda sounds good at WOT, but hopefully you wont be at WOT all the time in your "texas heat"

I don't WOT very often in this car, not untill I get an aftermarket temp gauge atleast.

jic 03-03-06 01:46 PM

ive had a single tip catcback with no resonator and a test pipe
i would never recommend goin back to that ever

I don't think it would be too bad.....the car as it sits now has no cat / resonator's, and a 3" downpipe/midpipe, still has the stock exhaust in the rear portion though....and a single tip muffler welded in (aftermarket) at the end and is not loud at ALL. It's too quiet personally....

I can hear the turbo's over the exhaust still right now as it sits when boosting. =O(

Mark McGuire 03-03-06 03:25 PM

I was configured exactly like Wargasm, with DP MP and RB muffler. Was a bit loud at WOT.
Sounded nice to me, but the police would definitely not like it. I'll be putting a high-flow cat in there next week to keep my noise profile lower, and to be legal. There's a big fine for no cat here.

axr6 03-03-06 05:58 PM

It really comes down to a matter of preference. I would get real tired of such setup for a daily driver. But, for my toy beasts, I always had as open an exhaust as I could get away with. My present FD has a DP, a practically open pipe performance Met Substrate Cat and an huge straight through Corksport exhaust. I love that wild, angry, snappy tone that reverberates between the hills of my homecountry. Still, it is nothing like the hordes of Harleys that frequent my Gold Country neighborhood with their obnoxious straight pipes.

I remember when I ran dual 3" straight pipes all the way from my front engined V-12 Lamborghini engine. As an owner of any Italian exotic, it is your undeclared duty to rev your engine to the enjoyment of the wider public. The sound from that exhaust had caused orgasmic joy to thousands and permanent anxiety attacks to the rest. I was usually AHEAD of the sound and I loved it. Was music to my ears.

Each to its own....

RX7LINK 03-03-06 06:53 PM

i picked up my car w/ just a pipe & tip. had the cats, but no exhaust. and the car sounds like a JGTC race car. its CRAZY LOUD. not recommended.. so i can't imagine completely strait. cuz u won't be able to hear your radio or anything at WOT. Plus Rotary exhaust sound is higher pitch than big blocks, so the sound isn't so pleasent

angelck022 03-03-06 07:38 PM

My fd has a straight through exhaust set up with a custom dp, mp, and greddy exhaust. The car is fucking LOUD!!! But I like it -- it all depends on what you're into. It definitely sounds like a lawn mower on some serious steriods at idle. And at wide open throttle the tone is like nothing else, definitely sounds like a race car. :)

Thats a good thing. You got a PFC? It WILL sound like crap. All straight pipes do. Ive never heard a good sounding straight pipe in my life. My car is absurdly loud with a resonator and straight through muffler. Why would you waste money on a test pipe? Your local shop cant mandrel bend and crimps are absolute shit. Seriously. If you want straight pipes buy an ebay midpipe and cut your catback off. And yeah its 2 bolts to unbolt your catback. Dont be so lazy. This is a horrible idea. Thanks.

yeah I know what you mean, it sounds sounds like ASS!!! I wish I didn't ever do it now.....it's so freaken loud!! =O(

I have to wait untill this friday to get the muffler re-welded in, the HORROR!!! =O(

yeah, the back portion is crimp bent (I know, not good.) but the DP/mid-pipe is 3" stainless steel tubing (mandrel bent)....

also the boost is out of control now that the muffler is gone, it creeped up to 13psi!! I immediately let off though, so no more boosting untill I get the muffler put back on. =O(

ehos 03-07-06 01:40 PM

And you're going to drive it like that on the street? If you do, get ready for some exhaust tickets.

If it's for the track, it would be banned on ours (98db limit, and that think will be closer to 110+ at WOT).
