2-3 hp, maybe


We don't have Hondas. We can't slap on an exhaust and get a billion hp.

2-3 for..just the 2.5 catback right? how much would the headers add?

No, 2-3 for the header+2.5" catback.

I only have a header and I can tell you it added much more than that...

how much would you estimate it added? and did it make any difference in the sound of the car?

tongue.gif you kids...

Go put your stock exhaust manifold back on and do a few dyno runs, then put the aftermarket header on and run a few more. You'll have a couple HP increase. An exhaust isn't going to do much of anything except make you louder. Unless you've got a dyno sheet saying you got super mad jdm tyte power gains then you're butt dyno holds no ground here.

is it okay for a 5sfe to go beyond 2.5"? perhaps 2.75"? or something..

#219
Unless you're going to eventually turbo it, I would stay at 2.5". The larger you go the more low end torque you'll sacrifice.

>umm.... it flows. I think that the engine is "breathing" much better now. but its kinda hard to tell just how much by the butt dyno. I find myself just listening to my exhaust sound instead of paying attention to my rpm's and speeds. But I have no idea how much the hi-flow cat helps.

When I pull up to a stop light and I hear my exhaust, I start to look around for which car its coming from. then I laugh at myself because, duh, its my car.

Edit:
Here's the pics from the exhaust shop. They did a good job running the ehaust over the axle.






this looks like a single solid setup from the flexpipe, are there no joints, or flanges, like to take it out in pieces if needed, just asking.


njccmd, sorry I missed your post. mine is not pieced together. it is all solid and welded together. I think that the exhaust guys I went to did a really pretty job. they even were able to take the 2.5" over the axle smoothly.

Should I put after cat first resonator and after that middle silencer or silencer first and after that resonator? Does it make any difference?

Usually it goes cat---->resonator----->muffler. What do you mean by silencer?

Well I mean muffler. I thought to put two mufflers and one resonator and 2,5" pipe. So should it be like cat - first muffler - resonator - second muffler or cat - resonator - first muffler - second muffler?

I thought to use Vibrant Ultra Quiet Resonator and also Vibrant mufflers.

Unless your running a y pipe, there is no reason for two mufflers.
Standard set up is cat--->resonator--->muffler
If you had a y pipe then that would come after the cat, and split in two, so you would need two resonators and mufflers.

Why not two mufflers? Of course it would be more quiet but does it restrict flowing badly if I have two mufflers?

Are you running a y pipe? Then yes. But if your running a single pipe, two mufflers is pretty much a waste of money. Come to think of it, I have never seen a car running two mufflers in series. Maybe two small resonators *and I mean small...like 5-6 inches. As far as restricting flow, I guess that would depend on what kind of miffler your running.

Nope.

Wow, 3? Thats too many mufflers. If you look at most set ups on here, they only run 1 muffler. Thats all you need. Are you worried about noise level?

Yes. I don't want race car sounds. So would this Vibrant ultra quiet resonator be on of the most silence resonators? Or should I put two of these perhaps?

You don't need to run a Y pipe. Don't listen to him.


Two mufflers is VERY common. It decreases sound without much of a decrease in performance. Run them like this - Cat - Resonator - Muffler - Muffler


Edit: If you run an ultra quiet resonator then there is no need for a second muffler, as thas is basically what Vibrant's ultra quiet resonator is.

Two mufflers isn't a waste of money. And you implied that two mufflers requires a y-pipe.

"If you had a y pipe then that would come after the cat, and split in two, so you would need two resonators and mufflers. " No, that is what I said. I never said that two mufflers requires a y pipe, It says that if you have a y pipe then it requires two mufflers, etc....

I would like to see some pics of a multiple muffler set up running on one pipe. Of all the time Ive been messing with cars, Ive never seen that. The only time Ive seen more than one muffler is on a true duel, y pipe, x pipe...etc...

Temp, if your worried about noise levels, then drop some money on decent stuff. I know my set up is posted on this thread, and its not "lawnmower" loud. Its nice and deep and the only time it gets loud is when I smash it.

The keyword is that you implied it.


Two inline mufflers

OK, first, for me, thats the first ive seen two mufflers run in series. So no resonator, muffler instead? Cant tell from the pic.
And secondly, I didnt imply anything, as I directly stated it. Had I said, your running two mufflers, your going to need a y pipe. Thats implying it.
95CelicaST
#236
Actually, that would be stating it. You're stating he needs a y-pipe.

Ok...this is getting real stupid now. I said if he were to run a y pipe, he need two mufflers. Not that if he had two mufflers he'd need a y pipe. As it is, this is getting way off the subject. Temp, you pretty much want a low exhaust without affecting performance, correct? Do what you feel is right, you want to run two mufflers, go for it. I think that you can get away with running the vibrant resonator (the ultra quiet one) and a muffler, then call it a day. Don't know much about that resonator because I don't have one, but someone on here has to have it.

I am due an exhaust replacement like last year.

Anyway, I have a Magnaflow cat due in soon. I also wano want an OBX tailpipe. What I was hoping for was to go under axle as opposed to over axle. I have a 7afte.

What are the implications of under axle.

Thanks.

If you're going to go under axle then you need to make sure that the exhaust shop fabricates the piping when your car is on the ground. This way they get the most ground clearance.
