exhaust mod opinions

[dohcfiend]

i am surprised i haven't thought of this be4. would having the crossover pipe remade out of mandrel bent piping add anything by itself or with a high flowing exhaust and a set or ported manifolds?

Port the manifolds is a good start. A larger, custom crossover is a very good idea over the stock restrictive one.

 

The ofcourse a new exhaust from the downpipe back is in order.

I say run a custom dual exhaust. Have the front cyl bank on one and the rear on another and put an X pipe a fet feet down the line and have it run dual all the way to the back

 

If I have the time and money I'd try it just for the hell of it

[gp90se]

dont have the room for a true dual setup, but a set of headers and/or mandrel bent crossover/mandrel bent exhaust will wake the car up.

depending on the year, some compainies make headers for the DOHC.

The new 3900s run a pipe from the front of the engine and under it, rather than around to the rear manifold and out one downpipe...

 

I don't know about subframe/oil pan clearences on our cars, or even if two pipes will fit side by side further down the car... but it's a thought. Don't know if anyone's tried it yet (probably not, since you'd need custom manifolds).

If I ever have the time and resources, I'll do it and post a full writeup
