i think i missed something here, alright i have a very slightly modded 351 windsor with longtube hooker headers. Just so i won't have to buy exhaust i was going to run it with them open mostly on the strip but some street driving. like all my dads big block cars run open headers even if its a stock 440 dodge. Is it different for small blocks or what b/c i really do not understand.

I think you need backpressure to run right

will i lose horsepower with not enough back pressure? and what will break if i run open headers

You really need backpressure in order to make the power you should be making. From what i've read I wouldn't go anything less than a midpipe and mufflers dumped. You can also burn up your valves if you run open headers on shorties, not sure on the long tubes.

ya i was gunna get some flowmasters w/ H-pipe and catbacks............and i guess i'll have to. does anyone know forsure that i'll lose alot of horsepower even with the longtubes

gizim_1132

Yes you will lose horsepower by a alot and it's not even worth doing it just spend the money for exhaust it will sound alot better and you won't die from breathing the exhaust in!!!!!!!

ya lol, what exhaust sounds good these days on mustangs...dont we have like an exhaust thread where everyone posts they're vids

gizim_1132

I am not sure about the exhaust thread but I would go with some go with bassani if you wanna spend the money in my opionion it's the best sounding exhaust for a mustang but you gotta have some deep pockets for it!!!!

What about the fact that it will just be f-ing loud. You would probably be the best off just running a normal exhaust system.

would it sound the same pretty much on a 351w...cuz he has a 5.0 and also has longtubes like me.
