Has anyone installed any shorty style or Kleemanns? Difficult, or is it really tight fit? You can say I have Moderate mechanic skills... Considering doing this with a buddy. OR should I not bother and have it don.e at an indy shop?

Thoughts? Saw BrainS DIY and looks pretty straight forward, but i dunno

Shardul? lol

What's the hardest thing you've done in a vehicle? I'll let you know how the header install compares...lol.

Simple, but your back will be a bit sore from leaning over the engine for a few hours.

Remove coil packs, use an open ended wrench as a lever, to pop the plug boots off. Go ahead and use this opportunity to change your plugs. Use a little dielectric grease inside the plug boots when you reinstall.

I've done shorty headers twice in a driveway.

I did VRP shorties in about 6 hours. Its not particularly hard, its just time consuming. You'll likely get bloody knuckles.

The hardest part is putting on the gaskets if the bolts back all the way out with the nut. That shiz made me mad.

Ive been contemplating this on my ramps...but not sure if id have the room...i do want to try it but I dont want to take 10hrs either...

Biggest problem if you have moderate mechanical ability is that you have to cut the cats out and weld up the pipes. The kleemann stuff does not really line up with the stock pipes either.
I always suggest removing the stock pipes completely and making new and keeping the stock ones for if you want to put it back or sell them.

You'd have enough room on ramps.

So I may attempt this...i had taken my 335 in too many times to get stuff installed id rather have the satisfaction on doing it myself now with the 55

Planning on keeping my cats...

Things I've done on my car/other 55k's...

SC clutch
IC pump
HE
split cooling and front mount tank
e63 bumper install
pulley installs
gaskets on valve covers
cps sensor
spark plugs

You tell me

AWOL

Then youre capable.

Bring bandaids

If you keep your primary cats in is there any welding involved??

ssonss1

Ouch! i'm sure tbal is ready for that, he sent me a pic last time with blood all over his white bumper

AKnight55

The kleemanns come with a down pipe that deletes the primary.. Pretty sure it wont bolt up to the primary (have to use the down pipe).. Welding is necessary with these shorties

kustom2k1

What AK said, I had a set installed by an indie MB shop, cost was 500 for the install.

tbal

Lol... im all in for sweat n blood...

Damn another dilemma, to delete cats or not... I'm just worried about emissions...

AKnight55

Pretty sure you could go with some aftermarket cats, but not the stock cats with these.

GT-ER

You are qualified then... It's really not that bad. I'm half way through a C55 header install and it's worse than the E55 install...yet still not HORRIBLE.

My previous G35 was HORRIBLE.

saleen01

you cant keep the stock cats, this is not a "shorty header" you need the down pipes and the cats will be deleted on the stock pipes, you'll need to cut the factory pipe and weld new flanges, mechanically its just time consuming, but if you haven't welded exhaust before, i'd leave it to pro.

With the prior work you have done, you can DIY. However talking to Cory regarding emissions/readiness, you can send the ECU to him and he programs a file that is separate from the tuned portion of the ECU to think that you have both cats so the o2s read correctly. He also said you can put new primary cats in, but still may have to weld due to the alignment of stock exhaust.

Labor quotes i have received is 5-6hrs. Komp55 has a good DIY on his evosport header write up. Only difference would be the welding of the downpipes/aftermarket cats if you go that route.

pullejo

I'm running no cats....just passed emissions last month with flying colors.

But...they don't do a visual here.

Jakpro1

Think that is impossible. First set of cats up top will be gone for sure.

with the Kleeman header install there will be some cutting involved since the primary cats are eliminated.

Roverron

In some states they will allow 1 to 2 readiness codes PA will allow you 1 readiness code.

novae500

VA is the same way. So options are:
-Send to Cory to trick the ECu with updated file
-get aftermarket cats as primaries
-talk to Bruce TTM, he can help you out with readiness...
