im going to use my revhard downpipe and flare it out to 3" right after the AC compressor and would like to know what bend pipe i would need to use to complete this. Can i just buy a 90 degree pipe and cut that up to make my bends to go back to the exhaust?

 

bump for some help please!

 

u trying to go from a 3"dp to a 2.5 exhaust system??

this reducer will work .. 3" on one side and 2.5 on the other .

no, im going from 2.5" to 3". I just want to know what pipe i should get to complete this. Can i cut up a 90 degree pipe or will i need a ubend?

 

just buy a U bend. its cheaper most of the time anyways.

 

i just need a BASIC SS reducer. nothing to bling bling like that.

 

i just need a BASIC SS reducer. nothing to bling bling like that. KTeller makes a straight pipe that flares, but how much power will i lose by having another foot or so of 2.5" dp, rather than that short piece if i flared it out right after the AC compressor?

 

I made a reducer for my DP by just getting a 3" tube, slicing it 8 times perpendicular to the opening, and welding the flaps together. Its just like taking slices out of it as you go, like pie slices.

thats a better idea than that ATP reducer, turbulance inducer. Also you could take some 14g flat stock, cut out the right shape and roll it up into a cone or whatever length you choose. That way there would only be one seam. woulden't take long to layout with some heavy paper and a compass.

 

ive seen a couple different flares out there. Ill find one. Its like a 3" long transition. The easiest thing to do would be to wait until the pipe goes straight back under the oil pan, then use Kteller's 2.5"--&gt;3" flared straight pipe, or just a reducer, but then it would go against the point of having the the 2.5" pipe as short as possible. Ehh. i dunno, ill figure it out. I only want to do this once ya know!

 

Is this what your looking for? Its a longer smoother transition.

Also, summit has slightly longer transitions sold in pairs for header reducers. they are $21 a pair i think.

 

3" radius 2-1/2" U Bend
2-1/2" x 3" transition
3" J bend

 

sorry to threadjack, but whats the idea on running the dumptube like that? or is it just dumping the exhaust directly under the car?

i think i'm gonna have to do one of these because all of the 5-bolt flanges i have found don't have enough material around the hole to weld a 3"piece of pipe straight to it, unless you guys know where to find one like that.

he routed it back into the exhaust since some people don't like the noise when the wg opens.

 

okay, i was just wondering why he used soo much pipe though? he could of used a few bends and have it go right into the downpipe (thats what i did) just wondering if there was a benefit to having it as he does.. thanks

 

If you dump the WG right into the DP right at the top around where it starts, you actually loose power.
