I am trying to make a list of every 3 Inch (76mm) Downpipe that is available for the EVO. If I am missing any downpipes, let me know! Under 3 Inches are not included.

AVO: Review by 05-EVO-GSR: The AVO downpipe is a nice piece made out of stainless steel. It has MIG welded flanges, mandrel bends, and it is 3 inches in diameter. The downpipe uses spacers for the lower tie bars and it is dimpled for additional clearance. It clears the ACD. The downpipe I am using has a slight neck down flange to bolt up to the stock cat. The newer versions of this piece do not have the neck down flanges.
DC Sports: Review by 05-EVO-GSR. The DC Sports downpipe is a beautiful piece made out of brushed stainless steel. It has perfect tig welded flanges, perfect mandrel bends, and it is 3 inches in diameter. There are no neck down flanges on the pipe. The downpipe does not use any spacers and clears the tie bars and ACD. This downpipe is a one piece design that elimates the cat and bolts directly to the cat-back. IMO this downpipe is the downpipe by which all others should be judged.

Works: Review by Matz. I have the WORKS ceramic-coated downpipe and love it. Fitment is perfect, no rattling or other noises from under the car. It fits using the OEM cross member braces, unlike the RMR downpipe I used to have (which required a new cross member brace because it dropped too low).

AMS: Review by TomsEVO: AMS also makes a 3" downpipe that is 100% stainless including the hangers and flanges. I have it and had no probelms with it although, I dont know if they have since changed this but when I got it I had to put some washers on the tie bars to get them to fit with the downpipe. great downpipe, perfect fit, and full stainless.

If you have any experience with these downpipes, post your results, good or bad.

how about Apexi?
, how about LPI?

oh yeah and don't miss expelir

 

Guys (and gal), he said he may have missed some and asked us to let him know which ones to add to the list.

 

True

 

I am running the Espelir DP. Full 3" and also uses the stock spring screws and stock donut. It clears the ACD and the bars w/o any spacers and it went on w/o a hitch. Check out my write up on it at www.teamadrenalineforums.com

 

Espelir downpipe is 2.75''.

HKS does not make a 3 Inch Downpipe. They make a 65mm Downpipe. 65mm = 2.56 inches.
Apex-i does not make a 3 Inch Downpipe. They make a 65mm Downpipe. 65mm = 2.56 inches.
LPI will be added to the list.
Tanabe does not make a 3 Inch Downpipe. They make a 70mm Downpipe. 70mm = 2.75 inches.
APS will be added to the list.
Works will be added to the list.
Espelir does not make a 3 Inch Downpipe. They make a 70mm Downpipe. 70mm = 2.75 inches.

 

Added to the list.

 

You forgot to add ours to the list.

How many of the 3" downpipes on that list neck down to a smaller size at the end to bolt up to the stock cat?

 

i got an Ultimate Racing 3" Downpipe

 

Are you sure on the Tanabe? I bought a used one and I could've sworn it was the same diameter of the rest of the exhaust which I measured to confirm 3".
