which would yield me more power? these two are my choices, which is better or are they both basically the same. the macs are 1 5/8 mid lengths and the slps are 1 3/4 shorties. would they be the same because the macs are mid lentgh headers? help me decide!!

 

Probably better off either way, since the Macs are 1 5/8 and longer, but the SLP's are 1 3/4 and shorter. I've heard Macs rust real fast and easy, so personally, I would go with SLP. I've got the SLP 1 3/4 shorties coated by Jet Hot and I could tell a good difference.

 

I'm going to disagree, and say go with the MACs. I've heard a few horror stories of SLP header installs, and that the plug access isn't much better than stock. MACs, on the other hand, have incredible plug access, and produce exceptional gains. I saw 3mph and .3 easy. As an added bonus, 20 minute plug changes and no need for fire sleeves, anywhere (I have an over-the-valve cover setup though). If you live in a relatively dry climate, don't worry about getting them coated, although it would be nice. If you live in a maritime climate, I HIGHLY suggest you coat them.

My vote goes for the MACs (although I am slightly biased... ).

 

I have the MAC's as well and I like them!! I have them heat wrapped so I have no idea how fast they rust. They have been on the car for about 6 to 7 years. I heat wrapped them two years ago and they still looked good!! Plug access is good too!
Go MAC front to back...you'll LOVE the sound!!

 

I got the SLP's because although called "shorties" they are nearly identical to the Mac's in primary length and routing. I liked the SLP stainless steel construction and I got them ceramic coated ($584 total).
The Mac's are reported to have the best plug access of all Mid/Shorty designs although I don't like the "slip joint" on the #1 primary. My Mac catalog list the headers for 93 as part #TF3593 at $469 with HTS coating (not ceramic) but I think the price has gone up.
I don't think there will be a drastic difference either way you go except considering where you live the SLP stainless construction with or without ceramic coating will ensure a rust free future.

 

Go with the SLP's if you want max power with out LT's. The SLP's will be harder to install and do plugs but they will provide more power.

 

thanks for you replies guys, the reason im thinking macs is because a buddy of mine is selling them to me, they are hks coated or whatever, im just gonna send them to jet hot to get coated, if i get them.

will the slps make much more power? originally i wanted to get the slp shorties but hes gettign slp shorties and hes selling the macs with y pipe for about 225 US. so if it isnt that much of huge difference ill take the macs.

 

all shorties generally put out the same power, there both good shorty brands id say whatever the better price go w/,ive heard slp's are more of a pita to install

 

SLPs are a shorty header; MACs are more of a mid-length header.

Just by design, MACs will produce more torque, SLPs will produce more horsepower.

 

so i should go with the macs then? the mac is for a 96, is there a difference?

 

Yes, there is a difference. You might have some minor clearance issues putting 96-style headers on your 93, since 96+ cars are OBDII and have dual cats. Also, you'll have some difficulty with the EGR and AIR systems, since 93s are also different than 94+.

 

im dumping the egr and air and emmisions. so that wont be a problem, the headers are on a 94 car now and have a single cat/ORP y pipe, (mufflex???) so that wont be a problem. i guess ill get them then, thanks

 

2 basic differences.

the first is you are looking at larger primaries with the SLPs which means the exhuast has more room to expand yeilding more power. next, the SLP headers are stainless steal which means they will outlast your car! im pretty sure the MACs are the same length headers as the SLPs. because of limited space available, any shorty header with the y-pipe included like the 2 sets you asked about will be same length or they simply would not fit.

 

so there worse then the slps then???

 

maybe my question should be could i hit 11s with the macs and my mods with the 150 shot? or will i be better off with the slps?
