Does the 4-2-1 header fit perfect on a LX 5 spd or would the motor mount still need to be cut.

Thanks alot mbow! so the shorty is the two piece one right? if so this is the street legal one that wont require any cutting of any sort?

Yep, the shorty is the 2 piece setup. You will only be getting one piece of it though, the header itself. It's the top section only.

wouldnt it be better to have both pieces? and since its two piec it wouldnt be easier to install with no cutting of the motor mount?
ps: sorry i got so many dang questions

If you're not going to get the 4-1 with high flow cat, don't waste your money on the shorty header. It won't be worth it. If you have auto, there is no cutting. If you have manual there isn't that much cutting, I think the DIY has too much cutting considering you can just take the motor mount out for the install. Do what you wish though, it's not my money.

I don't know what you are asking. The shorty header is 1 piece. The top-section only. You can get the hp downpipe to go with it but you'll end up having to deal with the o2 sensor again.

Ok....the header connects to the engine, other side of header connects to downpipe. That is the shorty header...

The race header w/high-flow cat is a 2 piece and requires mount destruction with a manual.

What exactly are you asking....I am going to snap a pic of my stock header...same as yours as we both have exs..right back

sorry im so confusing but i do appreciate you helping me ok i got that that pic is a shorty (just the top piece) now the two piece in the hp link would be illegal because normally the cat is welded onto the downpipe right? and if so then i could just get the hp shorty header and that random tech cat which comes with the downpipe and then the exhaust and im set right?

Well, a lot of states have laws saying that you can't replace a functioning cat for any reason. You would have to check your state's laws concerning that.

Also, a cat that is going to be as clean as the oe and not throw a cel, is definately not going to give a decent gain in horses.

If you want the downpipe, I would go ahead and get the hp race unit. If its the illegal part you are worried about, no one is going to know. Before inspection, just trade it out for the stock units. If you are going through the trouble of replacing the downpipe, you may as well make it worth it.

ok... so i've finally decided. ill get the hp shorty (which will show better gains than the dc). ill keep my stock down pipe with cat. and ill get the dc tcs exhaust. good plan? noticable gains?

You should notice a little bump from the header. The exhaust, you will probably only notice the sound and the looks. TCS is pretty heavy, about 50lbs, and probably isn't the best choice performance wise. However, get it if you like the looks and I hear it sounds great. I think you would be very happy with it.

yeah, i was thinking of getting the greddy evo but then i found out it wasnt stainless steal and my car is going to be pretty low so i need an exhaust thats low profile and wont crack open if it gets slammed on the concrete.

Now, would the DC 4-1 one piece header fit into my car without any engine mount cutting? Because you get better torque with the 4-1 right? And if I were to get the shorty HP header it would be a 4-2-1 header. So even though the HP shorty would have bigger piping, wouldn't I gain more torque with a slightly smaller piping header like DC? But then DC one piece would remove the cat, making it illegal, right? So, there's no way to have a 4-1 header legally?

This is the DC Header for our car: Link. it is carb-legal, and require NO engine cutting whatsoever.

This is the HP Header w/o high flow cat: Link, this is carb legal. also requires no engine cutting

Lets clear some things up:

1. the ONLY header that isn't legal (street-legal/carb legal) is the HP header W/ high flow cat.
2. the rest of the headers: DC, chikara, HP header W/O high flow cat, kamikaze are legal and require no cutting.
3. the ONLY header that needs the engine mounts to be shaved/cut is the HP header w/ high flow cat. here is a pic:Link

Wow, thanks for puttin' it down Desi! So, there is no legal 4-1 one piece header?

 
Rep Power: 0

Nope.. also..if you take it to a shop and spend an extra 2 hours labour...thee's no cutting with the HP 4-1 header either...but they do have to unbolt and lower your engne a few inches for the install..the mount cutting is only to fit the header into the engine bay...after that there arent'a any clearance problems..

Dang it! I wanted 4-1! Eh, I gotta go legal. Oh well... now I'm set, HP Shorty it is!!! Thanks everyone for their advice and comments!

how much are those hp short ones run for? are you sure its worth it?

my ebay one (98 bucks) worked good... till I snap my honda grade 5 bolt and got it stuck there... this happened twice too.. got one out... other one is still there, kinda lazy to drill... plus I'm lazy to reinstall the header.. lol.

believe it or not I felt some gains in the low end.... it really wasn't in my head! (rpm clearly climbed faster)

I got it for fun... now I'm going to keep it cuz I felt gains... I'm also going to by some header wrap for it...

header wraps are good for keeping the exhaust in the header hot, so the exhaust exits faster... it does have a bad side to it, that is it'll decrease the lifetime of your header... since it'll really be heating up in there... it may crack or etc. faster eventually... so think about getting it...

this is after I get that bolt thats stuck outta there... I think I may just take it to a shop, the threads are screwed up... gotta rethread it... too much of a hassle for me.

so yeah, u get what u pay for. but I think its mostly my fault for over torquing those honda grade 5 bolts...

(the grade 8s I use work super)

I suggest that one day... eventually when the stock cat dies, u go and get the random tech. highflow cat...

that'll be a long while though...

Is the reason the HP Race header is not smog legal, because of the high flow cat it comes with?
If i were to go with the HP shorty and later on get a highflow cat, think it would pass emmissions?
