Do You Know .........

I saw a downpipe that started at 2.5 in and after the flex joint it opened up to 3 in. Do you know which one that is?

most 3" down pipes neck down to fit the stock o2 housing, then flare back out to 3 inches.

Hahn Racecraft Eliminator Jr. maybe......... Uses a 2 1/2" to 3" flared section to bolt to the o2 housing. This is only one choice of many that are available.

The RRE downpipe does that-- starts 2.5" and turns to 3" after the flex.

even the Apexi N1 downpipe starts at 2 1/2" and flares out to 3" at the flex pipe.
