Downpipe Interest

[03Speed]

The is a company down here in Florida that was looking into producing a downpipe for our MSP. The size of it is 2.25" neck going into a 2.5" flex section. After the flex its also 2.5". There will also be a 3" high-flow cat, that can be interchangable with a race-pipe.

I was wondering if anyone would be interested in purchasing this, and if so what do you think would be a good price for this set-up.

 

[perfworks]

what size do you have now and why not 2.5 all the way?

 

[yashooa]

Hmmm I see

Good question there swine attractor (perf.)
250.00$ for non-coated stainless?
Yeah I wish...
Homer says give me donut.
Yash no I am a damn diabe-what-cha-call it.

I have the stock exhaust on right now, he is trying the downpipe on another MSP down by him (he lives about 3 hours from me). If he did a full 2.5 the bolts wouldn't match up and it wont be possible to have this set-up. He is going to send me pictures of what he is going to do. And once i get them i-ll post them for everyone.

 

[perfworks]

please do.

 

[yashooa]

awesome

I am waiting with baited (but o so fresh) breath.
WTF does baited breath mean anyway?
AGR please tell us cause you are older and, ahem, wiser. (werd)
Jest git it there son so we can afigure on it a while.
I have money to spend so hurry up before I have spend it on other things like drug rehab or insurance for the yung-ins.

Why would You use a 3" cat with 2.5 inch Piping?? that wont bolt up will it??

Hey whats up guys!?


I was goign to make a full 3" DP but the problem is that the flange from the turbo housing extention (not sure what its called yet) is only a 2" diameter piece, and If i make anything larger than a 2.25" on the neck, then you will not be able to install the nuts on the bolts. Also, the weld will get in the way and not allow the nut to mount flush on the flange.

The system conisists of the elbow which bolts up to the cat assembly using a pivoting setup. It has 2 spring bolts and a donut. I was goign to make it form the pivoting section back but then I decided to make it from the turbo extention. I will try to make the elbow in a 2.5" setup and have the begining of it reduced down to a 2.25" so it can fit in onto the flange up on the turbo side.

Form there back I will use a full 2.5" setup that will bolt up to your stock catback system. I will also be using a flex section instead of the donut and spring bolt setup that wears out after ti me.

I will be using a 3" highflow cat. Now you may ask why a 3" highflow? Well the reason behind that is so I dont have to make another partnumber and so I can keep my inventory down. The 3" cat WILL bolt up to the 2.5" piping with no problem at all. It will also supply more than enough volume then you will ever need.

I know some of you guys really want a 3" system but it's not practicle. Just to let you know, a 2.5" system will support up to 450hp. Just go ask all of those eclipse guys with the 2.5" systems and also read corky bells maximum boost. It has a good chart of HP vs. Piping.

Oh, I will also be putting an extra o2 sensor bung in it for those who will want to tune there e-manage, apexi- AFC with a wideband o2 sensor.

As per 03 speed, this set-up is for you guys Im all ears so let me hear what you guys want with your setup.

Happy boosting!

2.5 " will support 450 hp?

 

[Ryan]

im definately interested but how much?

 

[mspeedpro]

yayaya how much?? if i hooked the downpipe mentioned above to my stcok catback system- would it sound any better? is it an ez job that a complete idiot (myself) could do?

 

[perfworks]

its been discussed before that for street use at least 2.5" piping is more than sufficient.even when running a max of 10psi boost on the MSP'S.
if and when you decide to go to a 3'' downpipe then you will need to be externally wastegated because the turbine housing will have to be upgraded.
at that time you will have no problem to get a weld flange and a 3' downpipe..
if your going to 2.25 downpipe and then a 2.5" flex. i dont think you will see any noticable gains( at least nothing to brag about).
so if your increasing the diameter of the downpipe to 2.25 IMHO i would stay that way thru out the system for obvious flow characteristic advantages when bending.

Not sure yet, maybe 300-$350. I have to see what it will run me first. This setup will come with a Cat, and a racepipe. If you run with out a cat, you WILL get a CEL(check engine light).


About the first 3-6" of the elbow will be 2.25" then it will open be 2.5" piping. It will then go into the 2.5" flex and after that its 2.5" all the way back.

Anything bigger than this will be an overkill unless you get a tubular manifold with a different turbo setup. The T25 turbo will not max this out anytime soon.

Compliments of Corky Bell. He's an old dude with tons of experience on turbos and exhaust systems.

Cory Bell's
Maximum Boost is his book.

 

[ARunto]

where do i sign up?

 

[boostisgood]

Hook it up, and Im buyin, if the price is right

 

[AFaceInTheCrowd]

yeah i'm down for that. if aint too big of a hit to the wallet.

 

[suttonschinook]

I'm in. How much bigger is it compaired to stock? Pics? Thanks, Evan

 

[Exhaust Depot]

stock downpipe varies from 2.25" to 2". In between the two cats its only 2"

If the price is decent, I'm in. I'm told the downpipe is the big thing to overcome for the MSP exhaust. $300-350 seems fair if it includes a cat.

Will it be bolt on? Something one could do in one's driveway (or apartment complex) with some ramps?
