Should I Put A New Exhaust System? If So Should I Go 2 1/2 Or 3 Inch Piping

Or Should I Just Stay Stock?

I Just Got My 280zx Not 2 Sure Wat To Do?

 

Research. There's lots of info on this site & the www about 280zx mods & upgrades. Is your Z a turbo? Do you want to spend A LOT of money? Do you want to go really fast?

 

My Z Is Non Turbo. And Its A Auto.
Humm Well I Got A Quote The Other Day Est.$300.00 And Dude Said I Had To Go Bigger Piping And I Had To Change Muffler. I Asked If I Could Stay Stock He Said No. But I Wasnt To Sure So I Posted This Question

 

It seemed to me that when I went bigger i lost pickup below 2500 rpm but got more over 3000 rpm

 

Yeah So Big Is Good?

I Just Got This Car I Was Also Thinkin Intake Would That Help Out
Or Give Boost?

 

Go to a diff shop. It's not like OEM mufflers aren't replaceable... They would just chop it out & weld in a new one.

And a bigger exhaust alone won't do anything good for you.

 

I miss the jump at lower rpms. I got the MSA performance exhaust. google msa. Cost lees than $100 to have it installed

 

So Its Bad Then? Yeah And I Also Really Dont Want Loud Nosie?

 

Larger exhaust? It's not bad when done correctly and in combination with other upgrades. You should read this book:

 

U Did Oh? I Like That Jump.

 

Kool Thank I Be Sure To Check This Book Out

 

has anyone heard one of these with a flowmaster exhaust on it

 

I got the MSA exhaust too but i put on a header with it and mine still has plenty of jump. Do you have a cold air intake on it too? It has to breathe in just as well as it breathes out. I also took out the cat and bypassed the egr valve too. It has a lot more top end power now. New cam is going on in a couple of weeks!!!

 

Mine does.

Better flowing exhaust can do good things even if you change nothing else. It lowers potential engine temps, and mkaes for a better sound. Normally increases mileage. But, that depends on your foot. And with the factory induction system, I would not expect miracles. Mostly top end.

Put some triple weber carbs one, with a nice big cam, a good header, and free flowing exhaust, and expect more. But, it's all in the $$$. Unless you get lucky like I did. lol

 

yeah mainly to and from work some w/e i line it up with my friendz 300zx.

even with a huge whole in the muff.lol. she runz pretty good.

i was really think bout goin stock my friendz 300zx iz stock and it runz good

 

you can go either way but definitly take it to another shop, where ever you took it for an estimate is trying to screw you and DONT DO MIDAS!

 

ima go to another shop.

i had came across a racing exhaust some guy had bought he was letting it go for $100 but my money was funny at the time. maybe next time

 

i do remember the name

good thing i didnt buy.

yeah i should try ebay.

flowmaster? would that be any good

 

i really dont want to much sound.

stock nosie is perfect.

 

if you or someone can weld do it urself and just buy mandrel bent exhaust. alot of shops will do crush if u dont ask for mandrel because its cheap

 

nah man i got to take it to the shop. but im going to look for a cheap priced muff.

 

I am curious if there is some good flow bench testing between various makes and models of mufflers. I have found a few numbers.
I know flowmaster is not anywhere near the top. Better than stock. But, they have the best sound. imho.

 

u do not need 3in on a N/A, 2 1/2 will be fine, remove the CAT and you will be happy as well

 

Yeah. No one likes cats.
Well. Maybe tree huggers.

 

A Big Hole.
