Does anyone know where you get pre bent dual 2.5" front and mid pipes for dual exhaust?

I want to put dual exhaust on my 78 Malibu. I already have mufflers and beautiful ATR stainless angled tail pipes from a GN. I just need the pipes in front of the mufflers. To be honest I would prefer something that bolts to the cast iron manifolds even if I have to reduce it up there. Anyone know of a person or place that offers this?

Pypes may have it unless you want to come to a shop in Long Island :p

Which set of manifolds are you using? The new type that most SBC cars came with Pypes is the only one with them. If the ones used on everything '77 & older I'd go with Flowmasters. Now if you ended up one the factory installed "odd couple", right side new & left side older (think it was only 350's but it could be 305's too, early production?), you might be better off matching a set & pick the ones to work with them.

I used Pypes. They have two choices for cast iron manifolds. Two bolt or three bolt.

Try going here-https://classicmusclecarexhaust.com/c/quick-search/general-motors/g-body/pypes. They carry both 2 and 3 bolt Downtubes plus full G-Body exhaust systems. If you already have everything from the mufflers back, you'll just need to have an intermediate pipe fabricated to connect the downtubes to the mufflers.
