Not another 2.5-3" downpipe pic
 
I finished up my downpipe and added the wastegate return tube, it flares to 3" where the downpipe and wastegate return pipe meet.

did you use two 1.5" U bends for the dump tube? what radius? wondering if I should incorporate flanges then use bolts to fasten them so I can detach/attach it...get the picture.....uhr....flange at the top where it attaches to the wastegates >> flange 3/4 way down >> and a flange to the attached 1/5" pipe that enters the downpipe and just use some lock washers and bolts to fasten these two pieces together......hmmm just an idea...what do you fellas think?

A 180 at the top, then a 45, then a 90, the another 45 where it enters the downpipe. I started out with two 180s and a 45.

The original 2.5" downpipe is from revhard ($130), the 2.5 --> 3" reducer is from flowmaster ($12), the 3" flange from summit for ($3). All the 1.5" bends were from jcwhitney and ran less that $20.

I did all the measuring, cutting and painting and a buddy of mine did the welding (randy@hughlett.net), he's a great import builder so give him a call if you want some help with your project.

A bunch of people have IMd about making one of these for them but unfortunately i cant, this is just a hobby and I really dont have the time.

But the guy who did the welding does this for a living and might be willing to make a few of these. His username is "mochanic" hit him up on the IM and see what he says.

now bolt it all together and show them what the entire set up looks like all the way back past the cat.
I still think we should have gone all either black or grey, it looks kinda weird with two different colors. Alex's is the same way, and last night we decided to blast off the black and go all silver/aluminum... much better!

Oh come on Phillip, it was so much fun, we should do one for everybody on the board!

Re: Not another 2.5-3" downpipe pic (Mochanic)
 
I didnt like the mani or the turbine housing in grey but black radiates too much heat to do the whole thing black. I like this combo of colors.

Mochanic 03-09-2003 03:34 PM

Re: Not another 2.5-3" downpipe pic (philo)
 
Have you seen the new aluminum color that we did Alex's tubine housing in yet?
It almost looks like it was HPC coated!
I think you would really like it... and it reflects heat too. When you get over your smart teeth removal come check it out, and we can weld that band clamp stuff you finally got.

where can i find that reducer?

So i don't make another topic, what if i built a 3" downpipe that reduced to a 2.5" at the flange?

The reducer is a flowmaster unit from summit racing. Why would you want to do a 3 --> 2.5". The only reason we do the upper downpipe portion in 2.5" is so it easily clear the a/c compressor. If your cat and exhaust system is 2.5" I would just do a 2.5" downpipe.

I already have some nice 3" tubing laying around that i can use. I plan on a 3" downpipe, then have it connect to a flange with the reducer, then to a flex pipe, then to my cat. Should i just delete the cat with the Flex pipe? I still need a way of putting a cat on though for emissions...

if only I can post mine....

mine is strictly function over fashion, I flared it from 2.5" to 3" right after it clear the AC compressor after the firs bend off of the turbine housing...

What do you think of my wannabe setup? Should i just do 3" all the way through? i just bought a 2.5" flex pipe from RRE too.

Its DEI silcone high temp paint and holds up extremly well. We were tig welding some pipe that had been painted and even within 2-3mm of the white hot molten metal the paint remained intact. If it burns off its no big deal.

I used VHT 1500 deg temp paint on the manifold and turbine housing, it's still there...

find me a girl to break my heart, then I'll go to LA again heheheh LOL...

I used 2.5" from the turbo, then as soon as it clears AC compressor about 3" form the turbo, I flared it to 3" all the way back...
