now we all know that 3" is pretty standard for all our swappers.

what did you do for exhaust? custom from a shop close to you? make it on your own?

whatd the shop quote you?

how much was it if you did it yourself?

looking for general price quotes here, trying to plan out the finishing touches of the swap and the only exhaust shop i called said "theyd have to look at the car".

to cut down on costs i think im going to buy my own cat and muffler from summit (43 bucks for cat, 18 bucks for muffler, summit turbo muflers for the win!) i just wanna know if you guys have any idea what it will cost. i already have a downpipe.

i tried searching, but everyone just says they have 3" exhaust, not where or how they aquired it, and since they are all custom, was wondering what everyone did for it!

thanks as always

im pretty sure that 3 inch is too big... most swappers want more like 2.5, and i think mainly they do custom exhaust.

cheesy, if your not sure, dont post.
basicly you'll need to go to an exhaust shop, or someone like dave (DG PERFORMANCE) and have at the minimum a custom b-pipe made to mate your stock exhaust to the 3s dp.
however, doing it like that is extremly restrictive.
the MINIMUM size pipe i would use on a 3s would be 2.5"
with a turbo setup, the best exhaust is no exhaust.
depending on where you go, who does it, kind of piping used, ect, expect to pay anywhere from a few bucks for a custom b pipe, to closer to 500+ for a full stainless turbo back 3" setup.

3" turbo back SS exhaust with two SS magnaflow mufflers.

I would go for 2.5" with power levels less than 250whp unless you like the extra sound.

I have a 3" DP back SS custome exhaust made by a local shop called autolab. Cost $550, they did a great job and if I ever have any problems with it they told me to come back and they will fix it for free.

welll... this whole time i have been rocking the greddy SP exhaust with a dented 2.5in (more like 2in with the dent) mid pipe. it does ok and the car is still quick, but you can tell that i will benefit a lot when i got to a 3in.

DG's exhaust looks great but I just dont think its in the budget right now, im hoping I can get a 3" down to about 300-400 bucks by using a cheap muffler and cat

#12

dont cheap out on the muffler. its really hard to get a 3in ehxaust to sound good and not be so loud that you cant hear your radio. at the very least get a 100$ magnaflow. if u cant afford a few extra bucks for that, then what are you doing with a turbo motor?

For my exhaust i got a 3in. downpipe then had a custom 3 in. mandrel bend exhaust system made for it. I got a 3in flex pipe near the oil pan, gutted cat towards the center. I went under axel towards the back (i have great clearance by the way, even with a 3in drop) I used a Vibrant flat black muffler 3in straight through. (great sound) i think the under axel clearance depends on how the piping is bent back there.

not on my celi since its sold, but on my project car i'm going with 3inch downpipe to Electric Cut out, my friend has had it for over 3 years now and it hasnt given him any problems and its as close to no exhaust as u can get. Also because u can have stock piping u can pass inspections no problem and emmisions, o and if your messin around on hi way with another car and they got exhaust they'll get pulled over not u.

3" Turbo back exhaust. 3" Is the best way to go. sounds the best + no back pressure. Make sure you get a decent muffler also.

i had money planned out, however certain things came up (getting ripped off on my shell being the major one) that forced me to spend money on more important things (such as airbag and windshield, to pass inspection..)

If i can get better deals on the products i need to make exhausts i could make the 3" 3sgte race exhaust cheaper but at the current time i cant do it for less than what i charge or i would be loosing money making my exhausts. If anyone out there can get super deals on mandrel bend pipe, flex sections, flanges, v-band clamps, canisters.... let me know cause at the curent time i have to spend 95$ just for the 2 vband clamps i use on my setups! That is crazy!!!
At least now you know why the total cost has to be where it is cause parts to make it are not cheap. I dont like to make crap parts, so i buy the best parts, but the best parts are not low cost items.

What would be the disadvantange to running something like a 4inch strate pipe all the way back? I thought the turbo would give the motor all the backpressure it needs at the lower rpm, and it's best to have free flowing from there back. Is this just for race applications or something?

Dang it man, I know no one uses 4inch pipe. And I want to know why. I don't want to here things like it's pointless, and that's it. If your going to respond to one of my posts, give me a reason. Don't act like a little turd and say "LOL 4" thats utterly pointless," without explaining yourself. Please, just explain yourself. It rude not to. Even if you don't think it's rude, I do. And for future referance, when replying to something I've said, please keep that in mind. You are a very knowledgable person, please share that knowledge along with your comments.

EDIT: I just want to add that part of the reason I am curious about this, is because of the fact that sometimes turbo guys will unhook the exhaust at the bottme of the downpipe when at the track. I know the WRX guys were saying that at least. They could have been BSing me. And I know you can get those electronic cut offs to dump your exhaust up by the motor. So I don't understand how having a huge exhaust wouldn't have the same affect. I don't know how to run the numbers to find out what size pipe the 3sgte needs for optimum flow.

4inch exhaust are only a benefit on 6-8cyl turbocars. if u look at all the supra guys they all run 4in.

on a 4cyl car, 3in exhaust is plenty to allow no restrictions.

i run my turbo with an pretty much open downpipe (well right after the cat) makes spool time much faster..less restrictive

pure and simple you only exhale as much as you inhale...anything over 3" diameter on a 4cylinder motor is over kill because you simply don't move enough air..by the end of the pipe your exhaust is moving so slow that the newest exhaust is probably pushing out the rest of wat has slowed in the pipe

A 4" exhaust is NOT utterly pointless - particularly on a FF or FR car where the piping runs the length of the car. However, if you are running less than 400whp, it would not be cost effective because you are not going to see much of a gain. Above that hp level, you are correct Bulldog, it will improve flow and increase horsepower - more the higher up you go. On a "high power" turbo application, the best exhaust is no exhaust since it creates no back pressure. Heck, I would actually be willing to wager that you would actually see gains from a 4" exhaust over a 3" exhaust at 300whp too - just something in the neighborhood of 1-3 hp. Like I said, not exactly worth the added expense.

I am too tired to type a long response but suffice it to say that this is incorrect.

I did a 3 inch straight back from Down Pipe. No Cat.

Sounds really nice.

2.5 inches is a waste of money. Go all the way man!
