Exhaust

I have a '87 diplomat which I've posted here before, I added an edelbrock 4 barrel intake and carb. I would like to ditch the factory exhaust because how restrictive and wheezy it sounds(not right for a v8!).
I was looking at summit headers and was wondering if you can fit a set of long tube headers or if I have to go for short ones. I know the starter would need to be swapped with a mini-starter and I've heard good things about the summit branded ones.
I would like to put Dynomax mufflers on as well after hearing a set on a 318 someone posted sometime back on this site.
Any advice?

Headers https://www.summitracing.com/parts/sum-g9140
Starter https://www.summitracing.com/parts/sum-820441/make/dodge or https://www.summitracing.com/parts/SUM-820337

May I make a suggestion?

There are plenty, and I mean massive amounts, of discussions on our forum regarding what you are asking. Have a go at it: SEARCH is your friend.

The short of it: long tubes will work fine, you need to deal with standard things like steering centerlink, etc., or if your pockets allow (deep enough? lol) TTI offers choices which will make most of these a lot easier/simpler to deal with.

Regarding the rest of the exhaust setup: some kits come close enough, again SEARCH will bring all of these experiences to light, or you can do custom work.

Damn it, why do you have to be so far away. I've got a used set you can have. I'm not willing to go through the hassle of shipping though.

My opinion? I ran those style of small block headers for years. You're going to flatten those tubes that run under the steering link. What are your power goals? The factory 318 logs will flow enough for 300HP and will sound nice with a true dual exhaust and Magnaflow straight through mufflers.

Ive heard they are fine for 300hp but they are an eyesore everytime I open the hood. I am planning on either a 318 rebuild or a 360 magnum swap. Either of those will come later due to my current situation, but for now I want headers for looks primarily.
(Bad photo I know but they show the exhaust manifolds)

I had read several posts about this topic and I was asking about the specific ones in the post, but your reassurance that they do work is definitely helpful. It’s pretty tough to find information about M-bodies compared to A-bodies lol.
