I'm not sure If I should run these straight pipes or get a hole nother exhaust which i'm not really wanting to do cause thats pointless money$$ since i'm throwing the motor in for just like a year. This car is loud. I want to know if i should just say f it and keep it how it is or do sumtin about it.

 

I had a full system dual outlet with no cat or muffler. I ran it for 8 months or so. Wasent too loud except wide open.

 

striaght pipes aren't as loud as people make them seem....some of them seem to be quiter at idle than muffled exhaust systems....but they do excell at WOT...if you are running it out the back i'd say go for it, I dont' think it would pose too much of a loudness issue, unless you have a problem with loud noises....i'm running duals dumped underneath with spintechs and its loud as hell, btu you gotta think i'm getting pretty much all the resonance inside the vehicle, none of the sound is going out the back...

 

been running basically straight pipes for quite awhile now. It's loud, but not unbearably. Mine go out the back and are not dumped.

 

damn yeah, I think i'm just going to go off the 350 tpi y pipe with a bullet or some kind of glass pack looking muffler, and then a side pipe shooting away from the car on the pass side, Cause right now I have one on my 6 downed to the ground under the pass and it hits the ground and comes back up its horrible sounding too lol. all deep, glass pack and no cat on a 6 haha

 

while were on the topic of exhaust and streight pipes, is anyone here from PA and emissions exempt. if so how can you get your car emmisions exempt, do you need classic tags or not.

 

I run just headers only on my 87 GTA, i added two 12" extensions to each header and turned them out right behind the front wheels. With a sound like that there is no need for music.

 

sweetness, thats a good idea, Are they long tubes?

 

not really, its got a set of aluminum hooker headers and ive got a buddy that owns a muffler and radiator shop, i took the measurements and he bent the extensions and i just welded them up directly to the ends

 

what where the y pipe bolts to the manifolds

 

its like for instance a dragster, straight headers, nothing else, just with extensions so i dont leave exhaust crap all underneath the car. loud as hell too.

 

I bet its loud. Right now im running a Y-pipe with a cutout welded to it. And its loud. Im in process of redoing my exhaust.

 

i was waiting for someone to mention cutouts. how do you like them? ive been thinking about getting the electric ones. theyre only like 100 bucks right? i can do the install myself.

 

Straight pipes aren't as loud.. they are louder.

Ran around the block with mine just for curiousity sake... yeah.. more quiet than 'muffled' my posterior...



Just my opinoin though.. I could be wrong

 

My flowmaster is louder at idle then my buddies straight pipes. But he was louder at WOT.

 

hey deadbird is that your exhuast??? I would like to do something like that. Thats nice piping too, wheres it fire down at? and how much did it cost? I WANT IT!

 

often times muffled systems are a little louder at idle. it has to do with the fact that there is more air turbulence in the system, more air turbulence = more vibration = more noise. To put it simply.

That's why you will notice almost 95% of the time, that going from manifolds to headers will make your idle tone quieter, but wot louder. At idle there is less turbulence because it flows better, but after that it gets louder because more air (noise) can get through.

My friend's IROC with headers, cat and a flowmaster 3" american thunder idling is as loud as my car when i first start it in the morning. After it warms up his idles louder. But when i press the gas at all it's easy to tell whos flows better.

 

With the straight pipe above mine was open header loud at idle and open header loud at wot.
Louder than when I fired up my old edelbrocks open header easily.
Obnoxious no matter what though.

That's a picture of half of it when I was making the h-pipe. It goes 'straight' out the back. I believe I spent around $220 in pipe including the 4thgen tips.

Here's an older, not quite finished pic of the rear...
