I got my custom exhaust finished today.


Here is the full detail.
3 inch Y pipe.
Then tommorow the test pipe is going on there where the cat is.
Then the 3 inch custom b pipe.
all welded onto the stock exhaust!

It doesn't sound too loud.
And my car feels like 1000% quicker

 

100% better. So assuming a 7+ second 0-60 you're running 3.5+ and your quarter mile is below 9 seconds. Sign me up for that exhaust!

 

Yongjun,
Do you think that you have lost any low end power with the 3" pipe? You are N/A aren't you? Glad it worked out for you. Keep us posted!
Lata-

 

My question exactly. I'll be particularly interested in hearing your response once you've got the entire exhaust put together, yongjun.

 

Is your exhaust mandrel or compression bent? I had mine done but it's compression because nobody around here in Boston does mandrel.

 

Please repost the noise levels after you have done everything. I'm curious to know how loud it'll be then.

 

well to me the low end feels about the same.
But after it hits 3500 RPM's man oh man
I'm NA for now. Not for long.

And yes its madrel bent

 

how would u think about ur custom exhaust compared to cattman ypipe with hks exhaust??

 

Pics?
I have like 60 pics.
Just need to u/l them all and copy them to my HD
wanna do it for me?

 

Too big buddy, but glad you have it.

Any pics?

 

Compated to the stock b pipe and such.
My system is better

 

how would i make a custom bpipe?

 

go to a muffler shop and ask for mendrel bent.
Not press bent

 

wuz the difference? and wut is it?

 

Most shops do not have a mandrel bender. They buy mandrels pre-bent (they look like horseshoes). Then they cut them and weld them into place. That's how my exhaust was made.

The mandrel bending process maintains a constant inside diameter even through pipe bends. Flow area remains consistent, increasing flow more than 35% compared to stock, crush bent pipes.

Kev's comment is correct. 2.5" diameter piping may be too large for proper scavenging of a NA engine, let alone 3". If I had it to do all over again, I may have opted for 2.25" piping. But 2.5" piping is what I've got and I'm sticking with it.

 

did i ask you FOO!?! j/p thanx

 

sounds cool YJ! So are you going to put Vicki on the bottle

 

BTW
This gives you a hint of how loud my car is.
I will get a mpeg of it once sx7r gets here.
I went to the parking garage by my house.
And i just cruised.
Well i decided to stomp on it.
There were 3 lexus parked in a row.
All three of their alarms went off.

I'm totally satisfied

 

damn boy!! hahahahhaha. hm... are u ready for some hefty fines?

 

For what?

 

I hope the pictures look better than that mirror!

 

 

jOO mama
