Exhaust Question

[hemihotrod402]

Ok, so most of you know that I am planning on swapping to an EFI 351 down the road, so I really don't want to spend the money on expensive headers. However, until then I would like a better exhaust note, so my plans would be to delete the cats buy running the catless H, probably magnaflows, then run those out of the stock tails. Now, the question is should I try to pick up some stock mustang manifolds or a set of lincoln logs before I do all of this? Again I'm going to have 351 swap headers eventually, so I don't really want to spend much as far as that goes.

Are you planning to run tubular manifolds after the engine swap? In that case, there's no harm in getting a full 2.5" system (or do 2.5" crossover pipe to 2.25" S-10 midpipes to 2.25" in/2" out mufflers to stock tailpipes, or whatever you prefer) to mate up to stock 5.0 HO tubular manifolds, which as you know can be had very cheaply. In my testing on my P72, I found that an offroad 5.0 Mustang crossover pipe bolts up to either 5.0 or 5.8 tubular manifolds equally well, though I'm told TOTCG had a different experience with the same vehicle when he tried the same thing with a BBK catted H-pipe.

Otherwise, consider doing nothing for the time being and saving for real headers and a bigger exhaust later on.

Yeah, I agree with 1987cp. I did BBK shorties with BBK H-pipe. I used half of the mid pipes for a 1994-96 Impala catback which set the mufflers in the stock location of the CV. I then used the tailpipes out to the Trans Am exhaust tips. That was way before I thought about doing a 351W swap, so I will be getting the swap headers and 18" glasspacks for tailpipes to quiet down the engine.

what do you consider "expensive"?

[Lincolnmania]

look on corral for some inexpensive used aftermarket shorties (stay away from mac!) or use a set of ho shorty headers......do it all in 2.5" and later down the road when you do the 351 swap, get the bbk 351w swap shorties

[1987cp]

what do you consider "expensive"?

$25, unless it's for 4" exhaust tips or trunk-mounted stereo equipment. This is GMN, after all.

I consider a new set of aftermarket 302 headers that are just going to be replaced expensive. If I could pick up a set of aftermarket headers for <75 dollars I would jump on it, or a pair of mustang tubulars for next to nothing.

It wouldn't bother me if it wasn't for the fact I'm going to be forking over 350 bucks in the future for the swap headers. I have no problem with that, its just spending a lot of money twice.

I will sell you my stock mustang shorties for shipping cost if you want them. I have o2 bungs welded in the collectors, but you can buy plugs and use the ones in the h pipe.

What's wrong with 4" exhaust tips?

I have trunk mounted stereo equipment,adds about 50hp at the wheels. :3gears:

I had it dynoed.

[hemihotrod402]

I had it dynoed.

desktop dyno FTW! lmao

[jayh]

I kind of feel the same way about 4" tips on 2" pipes, thats pretty much the definition of ricer


buy some headers used for $75-100, then when the time comes, sell them for $75-100, even if you lose $25, so what?

building a hot 8.2 deck motor isnt that bad of an idea depending on your goals

[gadget73]

Headers aren't going to do a bunch for you as far as exhaust sound goes, but you sort of do need them to bolt up a Mustang H pipe. My vote is on stock shorties or cheap used aftermarkets. No point spending premium coin if they are just getting replaced in a year or so.
