I'm looking for headers that will still allow me to pass emissions. Is that possible.

Any help will be greatly appreciated.

Just buy shorty headers. EC ones are fine.

From what I've read on the forum I would need to get a new cat, but wouldn't replacing that cause me to fail emissions? Basically, I'm looking for advice on the right combination to pass emissions.

Thanks

The shorty ones connect onto your downpipes which allows you to use the existing cats. Its easy remove the old headers and install the EC headers. Cats are still intak..

Great, thanks I'm upgrading my ECU and TCU, then swapping my springs for H&Rs within the next two weeks. I'll most likely order the headers after that.

My longtube headers with 100cell racecats have no problems in emissiontest.
Brand of cats are :redback(australia)
Had 200cell magnaflow earlier, just crap!! do not buy!
Problems with emissions and core 'pyramided' and got burnt and furter on fell apart.(end of season, long after emissiontest, at the test, the cats were new)

Are you in Sweden? I think the rules may be different in comparison to New York.

If i remember correctly we have the same values as in california.

Just looked into this subject a bit more and it looks like I should be able to pass, but I'm not 100% sure.

From what I read the kleemann long tube headers are the way to go. However I'm having trouble finding that redback 100 cell cat for sale in the states. Does any one else know of any other good 100 cell cats?

Thanks

Did some more research on the kleemanns headers + downpipes. From what I read the headers bolt directly to the factory exhausts. The downpipes omit the primary cats.

This sounds great to me, but has anyone experienced emission issues?

Thanks!

Ackime Snow

I ordered the kleemanns. Talked to my mechanic and he knows a few places that I can pay off.

find a place that will pass your car for some extra cash...solves all problems

my car is registered in CA...I have mid length headers, high flow cats, o2 sensors disabled

Ackime Snow

That's what I'm doing, headers and down pipes ordered!

Amir_AMG

you will love them! remove the resonator, secondary cats, and add a pair of high flow cats (200 cell is what i did)

Ackime Snow

I'm pretty sure the kleemanns headers + down pipes omit the the cats and resonator.

Don't think I need cats, right?

I'm so excited, package should arrive at my guys shop October 1st.

Amir_AMG

I have the kleeman headers and downpipes...they will get rid of the primary cats only, I was just suggesting getting rid of the secondary cats and resonator for better flow and sound..make sure you get a tune as well

Ackime Snow

Okay I'll tell them to ditch the resonator during installation

Ackime Snow

The link you posted for the high flow cats, what size did you get? See picture

Amir_AMG

I got 2.5" high flow cats, make sure they are pretty short in overall length, as there isnt much space to work with (at least on my CLK) the magnaflow ones I got were 8" overall

Ackime Snow

Ordered!

Ackime Snow

Got an ECU and TCU tune on the way

Ackime Snow

Installed
