I considered that, but I'm just afraid of the way it'll look. On the flip side about dropping the rear, it'll be much easier to drop the exhaust, to remove the transmission, which I seem to remove MUCH more than the rear end....lol

If you fit the 3" you won't regret it.... it sounds awesome compared to a 2.5" system. Let's face it guys we all want performance from our cars and the 3" don't hurt that effort and the exhaust note is bitchen... and what true hot rodder does'nt want that?

My engine is going to want 3" exhaust. If I can't get the 3" tailpipes to clear, I'll just leave it as is.

i struggled to find anyone with pictures of 3" exhaust when i was looking. one person posted his setup for me that he handbuilt and did a decent job.

i couldn't find anyone locally that had a mandrel bender. the main reason i wanted mandrel bends was for looks. i didn't want to see a bunch of crushed bends.

if you are going to have people look under your car at all, then try your best to not run them under the axle.


i don't believe you have the mach one or rear valance with exhaust cutouts, so yours should be a little easier.

the magnaflow 3" kit stops short of the valance. or at least the kits i've seen were short.

this is a 69 staggered shock car with 3" i saw a mecum a few years ago when i was looking for exhaust setups. it really looked like the magnaflow kit to me. maybe others can post pics of their magnaflow setups.







this is my car.

Thank you very much. That looks great. You are correct in saying I do not have the Mach 1 valance, but I thought about putting one on there. If it makes the exhaust more difficult, I probably won't.

That looks like a really tight fit. What I would like to do, is turn them down behind the valance, flush with the bottom, so I don't have tips.

Side exit!

I don't know if 3"oval would benefit my engine, but side exit would look and sound awesome. I have 2.5"system to the mufflers and 3"oval exit out the sides.

I wonder if I would benefit from a 3"oval system?

There is no way I'm putting side exits on my car. Not going to happen.

Thank you. Not a great idea for a track car either.

How is side exit bad for a track car? What track are you referring too?

This is the route I went with 2 1/2". I bought a Flowmaster tailpipe kit from summit for an Olds cutlass - mandrel bent. Cut it up and it was a LOT cheaper than buying bends. That said, its a BIG job that goes on and on. In the end you get a nice system laced right where you want it. I was lacing around a custom Watts link. 3" is definitely doable with no link - there is room, it just takes a little artistic flair to do it elegantly so it doesn't rattle.

The Magnaflow system looks good. I think I will give that a try on my 65. Hopefully it wont take any major reworking to fit around the 4-link.
