custom exhaust

anybody that has a custom catback want to share what they used to make theirs? on a na tha is

if you do a search for "custom exhaust" , you'll find 50 threads on what people have done.

good point...i never think of the obvious things, i decided to go the way of a custom exhaust, i see alot of people used dynomax mufflers in theirs...is there any specific one that sounds better on our cars?

dynomax's website has sounds of their mufflers, the stainless steel ultra flow is a little more sporty sounding, where as the ultra flow welded is a little deeper... I think some guy on 3si sells custom exhausts... he's the maker of the N/A modding bible I think... oh yea and btw dynomax's are really freaking loud so you might want to leave your intake resonator on (just in case you were thinkin' about removing it).... that is, unless you like that loud ass sound...

ok thanks, i already replaced my intake with a polsihed pipe off of ebay...looks mostly...so your saying with what i have now...3sx downpipe and race pipe that a custom made catback with a dynomax will be rediculous...what if i get a high flow cat insted of the race pipe?

You could do what i did, instead of doing a catback have a true dual system custom made, there is a video on here somewhere that shows what my setup looks like, it performs and sounds better than a cat-back would.

3KSL95... a/b how much hp do u got?... and I've heard that the underdrive pulleys are pretty dangerous, especially for 3s's... I've got a/b the same mods... except the flywheel... I was just wondering how much all of that added to your car..

from what I've heard, converting your car to a true dual exhaust isn't worth the HP rating in the end, b/c the extra weight you gain will balance it out... but I mean that's only what I've heard...

And Beef, lol yea if you've got a DP and a race pipe with no cat you're gonna' be really loud... you could get a high flow cat if you want (I know a place that sells em' for like 80 bucks) but I mean it would still be loud... just stick with the setup you got, and if it's too loud you can put on some stuff like silencing tips (IDK if those work or not) and put your intake resonator back on... it's all up to you though man...

i prefer the deep sound myself. custom exhaust from the catback is a cheap gain. in my city the guy customized my exhaust(y piped) for about $120. later i found there are cheaper.
my mufflers are from spw, they sound really deep and powerfull....oh wait........my car is powerfull lol

^lol, yea man custom exhaust is a good way to go if it's done right... but yea dynomax muffler's will probly sound nice with your setup man... the best mufflers (in sound and duration and look IMO) are borlas, but they're really freakin expensive...

if and when you get your setup done man, I'd be really interested in hearing it if you could somehow find a way to record, and upload a sound file of your exhaust setup I'd be really interested in hearing it.

im gonna try to get it as soon as i can but being still being a senior in highschool its tough...i mean i work 5 days a week but i also have to pay for my car and my insurance, and all of the fun stuff that goes along with owning a car...the way its looking im thinking mid november early december before I am able to get up enough to pay everything off that i already owe (thats including the price of the catback...wishful thinking) thanks for everybodys help to

I was in your place last year Beef... it ain't easy... but once you graduate... if you work full-time for awhile... things will come... I've just been setback by so many things going wrong... and this morning my car started making a funny whooshing sound (while I was sitting still)...

I do plan on recording my exhaust sound... I may change the setup, and if I do, I will definitely record it before changing anything... and after as well

Mike, im not sure how much hp i gained from my mods because ive never had a chance to dyno my car, but the gains were very very noticeable especially in throttle response and acceleration. As for the underdrive pulleys they're not to bad, the 3sx pulley is a great mod it only weighs 1.6 pounds as opposed to the 7 pound stock one and its roughly the same size so its not dangerous really. All told i would say my mods give me about 230 - 245 at the crank, but thats just a guess.

thanks, I was really wanting to make sure it was worth the money before I kept adding on these little things here and there... to my knowledge, since the pulleys are on the bottom end of the engine... wouldn't the underdrive pulleys (made for DOHC) work on SOHC, sry this is a little off-topic... but it's got me wondering..

well one of my good friends pointed out to me that his uncle works at a custom exhaust shop...so if all works out i should be getting mine really cheap...hopefully pretty much just the cost of the materials/muffler and a little something for his uncle

well this is completely off topic but i cant seem to figure it out...how the hell do i make a signature? i cant figure this out to save my life for some reason

on the upper part of the screen there is a purple box with your user name and beneath it it has a link that says private messages, click on that link and it will bring you to the PM screen.
at the top of the PM screen there is a tool bar right below the box with your user name that has stuff like...avatar, profile edit, and signiture edit (etc.)

there may be another way to get there, but that is how i do it

hope that works for you

thanks

Yes the underdrive pulleys are the same for sohc and dohc, i also got to thinking with my mods 230-245 is way conservative, its prolly more like 240-250

aight... thanky... also, what is the difference in the underdrive pulley on 4caroption.com... because that's only $45...

also, how hard is it to change that pulley or would you recommend getting a shop to do it..

Hmmm. im not sure what the difference is on that pulley on the site it doesnt say what it weighs so it may be heavier im not sure, but its very simple to change the pulley you just need a socket wrench however you have to be carefull when putting the belt back on if youv'e never changed a belt before i would let someone who knows what theyre doing do it, but a shop will charge out the ass for it.

Well, I'm planning on changing the water and oil pumps... I guess I'll do this all at once... it'd prolly save some time...

btw, I haven't looked, so is there an automatic belt tensioner.
