lately ive been hearing alot about people going catless. would there be any benefits for me to go catless in the spec-v?im guessing all i need to do is buy a new exhaust system that doesnt have a cat on it? not too familiar with how that all works, so any advie helps alot!

Sure it would help... but you won't gain much until you put a header on there.
You will also want to pick up an O2 sim.

hummerman88 · 01-04-2006, 08:35 PM

o2 sim?

Maverick31 · 01-04-2006, 08:38 PM

Yes, it tricks the ecu into thinking that you have a cat. Its not a must... if you don't mind seeing a SES light, then I wouldn't worry about it.

specVogel · 01-04-2006, 08:38 PM

you should get a header stat. it replaces the first cat so you will need an o2 sim. there is a problem with the primary cat breaking up and the particles getting sucked into the cylinders and scoring up the cylinder walls. there was a recall for a bunch of specs that had their header/cat replaced but some still expierienced the same problem with the new updated cat. i got my header for 160 bucks with an o2 spacer that keeps the check engine light off. there is the same header still for sale for 150 now.

hummerman88 · 01-04-2006, 08:40 PM

could you please PM me with the details on the headers? i'd like to look into getting them

Maverick31 · 01-04-2006, 08:40 PM

BTW- I don't know of any shops who make a header-back exhaust system for the Spec V... you're going to have to buy a cat-back, then a downpipe.
www.hpautoworks.com sells a nice downpipe for the Spec V, and they sell good priced exhaust sysytems, I would check them out.
Look into the APEXi WS2 exhaust, its a bargin.

That problem doesn't seem to apply to Spec V's after the year 04.

But I do think that he should buy a header as a first mod... it easily makes the most power (as far as a staight bolt on).

specVogel · 01-04-2006, 08:47 PM

it's not supposed to be a problem for 04's and up, but i have seen it.

Maverick31 · 01-04-2006, 09:04 PM

Well, nothing is impossible. Doesn't matter, he should buy a header first.

2000MRDC2 · 01-04-2006, 10:53 PM

buy a hotshot,theyre the cheapest, then do hpautoworks downpipe, and Nismo cat-back my brother had the nismo cat-back and it sounded awesome

NISMO catbacks are pretty expensive... the APEXi WS2 looks/sounds a lot like it.

koho2731 · 01-05-2006, 01:49 AM

Don't cheap out to much on the Header the OBX crap has been known to crack. I had the Nismo w/o cat and I loved it. Also if you want to go cat less you should ck out the Stillen , DC, and Strup headers that take out both cats.

There shouldn't be a big difference between the two.

What the are you talking about I've driven two with two different setups and neither were that bad. Open header on the other hand was painfull

I made the sticky how-to on www.b15sentra.net for the o2 simulator.

As for the going catless, just remove the pre-cat by buying a shorty header. I never had any problems with my aftercat and my car sniffed clean too. RIP my 02 Red Spec V

Actually, I agree with him about the Spec V sounding like ass. When you remove both cats, the Spec V will sound like a clan of bumble bee's flying out of your ass.
