2 1/4" vs 3" exhaust for low boost
i found an awsome deal on a full stainless 2 1/4" magnaflow catback for $300 shipped and dont knock magnaflow because they make quality products, thermal even uses their mufflers and resonators for their exhausts. but anyways i am starting to consider going turbo on my d16z6, if i did i would only run 5-7 psi. how big of a difference would 3" be compared to the 2 1/4" at low boost and would it be worth passing up this deal and saving up for 3", remember i am on a budget. thanks for readin this

I agree. With the horse power you will be putting out 2 1/4 should be about right. You figure cars that put out around 200 horses have 2 1/4" exhuast systems. I'm going be running 2 1/4" at around 5 to 7psi also, let me know how it goes with yours. You could always upgrade later, although it will mean an increase in noise.

thats kinda what i figured that for the amount of boost i'm planning on running the 2 1/4" would be fine. of course the 3" would be better for any turbo setup but considering my situation i think i'm just gonna go with the 2 1/4". thanks for the input

was it a straight through muffler or was it chamberd? 300 isn't to bad but I'm gonna build mine, it'll be cheaper than that. I've been contemplating 2.75...not sure

first of all, you wont run just 5-7psi. you will turn up the boost. thats like saying yer only gonna knock up natalie portman once when you hit it all week.
secondly, its 2.25 right? has a resonator right? the sound is going to be different and quieter because of the turbo.
do the turbo right and you wont regret it.
just so you know.. everyone says they are gonna go turbo... buy the turbo before the exhaust... cuz i said so.

i made 270 hp 229 ft/lbs at about 11 psi w/ a greddy 2.25 inch exhaust......on a b18b
however, the next exhaust i buy, will probably be a 3"

I think you will be very happy with the results of switching to a 3 inch.

i saw a test on turbo mag that went from 2.25" to 3" and they gained 3 hp, but that was at 7psi. they stated the gain would have been bigger w/ high boost.

What is a quiet 3'' exhaust? With size incress i am allso guessing that you get in increase in DB levels.
I want to keep the noise tolerable.

Re: 2 1/4" vs 3" exhaust for low boost (sushibug)
i'm thinkin i might just go with the magnaflow though cause i'm not even %100 sure if i'm gonna turbo my car cause i have high miles on it and i cant afford a second car if somthin goes wrong. I think i am gonna focus more on suspension for now and wait to build a motor till i get a swap later down the road. thanks for the replys though

basically the only option would be custom w/ a really large resonator (3" magnaflow resonator thats like 18"+ long)
@ 10 PSI noticed a big top-end difference when I switch from a crushed bent 2.25" custom flowmaster exhaust, to a custom3" straight exhaust.
