which long tube headers do i need that will fit my x pipe or what do i have to do to make them fit?
i heard you have to lift the engine or something... any feedback on cheap good headers and what it take to intall them to my x pipe.

 

sorry guys but stupid ques...
can you still run cat's with the longtubes.. I'd like to try and stay emmission test legal

 

well yes, you can run a high-flow cat setup with LT's as seen in the SLP short assembly X-pipe. thing is, your still not emissions legal. even moving the cats is illegal. but hey, its only illegal if u get caught

 

So even with Long tube + cat's it'll fail emmissions test?..
in Ontario Emmissions tests are required every 2 years, i believe

 

Everybody says so, but I haven't seen a person actually try yet. The easiest way to avoid this would be to install real cats in place of the highflows when it's time for your test, then put the highflows back in after.

 

This is a good idea.
I also think Ontario is abolishing drive clean in 2008 so it won't matter in a while. as long as visually, the cats are there i'm sure the police will leave you alone.

I'm gonna do some digging.


If anyone has Long tubes + highflow cats and has passed emmissions plese post

 

There have been a lot of posts about this.

I have Longtubes and High Flow Cats, and it will pass a smog test ("tailpipe sniffer") with no problem. As far as I know, any set of performance high-flow cats will pass the test.

The issue is that in some areas, it's illegal to MOVE the cats. So even though you still have cats, if they're not in the stock location then it is technically illegal. However, the only way you'd get hassled over it is if you had a REALLY **** inspector. Like I said, you will pass the tailpipe emissions test, and if the inspector looks for the cats on your car, bingo--there they are.

Vidgomd, you can't install longtubes with your X-pipe unless it's specifically designed to work with headers (in which case you'd already have them). Sell it on Ebay and buy a set of longtubes with the matching X-pipe. The "OEM Style" x-pipe is not the same as a header X-pipe.


The Hooker Longtubes are the cheapest that I know of. They make them in uncoated and coated versions. Go look at Summit Racing and you should find them with no problem. I think the uncoated ones are $500 and the Coated ones are a hair over $600.

I'm fond of the Dynatech kit. Yes, it's expensive at $1400. BUT, that's not that bad when you consider what it includes:
Headers (100% stainless, and extremely high quality)
X-pipe
Pair of High-Flow cats (cats are NOT cheap due to the rare metal catalyst inside)
Full set of gaskets, hardware, seals & O2 sensor extentions.
...it is literally a bolt-on kit, nothing else required.

There is a kit without the cats that costs about $400 less.


Even if I was going the low-budget route, I'd definatley get the Hookers before a set of shortys. There's just no sense (to me) in going through all the work and spending several hundred $$$ on shortys, just for a measly 3-5 HP.

 

In North Carolina they've basically reduced our annual inspection to: - (from observations and talking to the techs)
- quick look over on the car to make sure all of the lights work
- cursory look at tires to make sure they have some tread - never seen them actually measure it
- and then an OBD-2 scan.
- If you have a pre-97 car (OBD-1) then you get the basic safety inspection even in counties where emmisions testing is required.

If you've replaced your battery in the last 2 weeks or have a check engine light on - they wont even test you now. The car must go through all of the drivability tests built into OBD-2 and the battery replacement or dead batter will erase the information. I don't think these guys would have any clue on where the cats were or should be - they didn't even look under my cars the last 2 times they've been in. So if the cats are there but moved - as long as it doesn't throw a code you should be fine. This is probably one time you want to go to Jiffy Lube!!

 

I was thinking about putting on the dynatech long tube headers with cats and x pipe. Does this require a tune, and is it true you have to lift the engint to put long tubes in?
