If so how do you like them? How's the fitment, quality and power gains feel?

03svtkiller

Those are the same as kleeman headers, fitment isn't an issue, power gains anywhere from 20-30whp.

I was going to say, I didn't think EC made mid-length headers, long tubers yes.

03svtkiller

Yea they came out with them last year.

680 shipped PM me I have some in stock

I had them installed not too long ago, I came from modded manifolds to these. I think they look good, I also had the collectors cut and opened up to 3" pipes to mate my exhaust. I will know more once I hit the track and dyno. I'm curious to see if my top end is better than before

it will be interesting to see the difference in modded manifolds vs mid length will all other thing being equal

Hulk

Yes I'm very interested in seeing that as well

what does the butt dyno say?

Hulk

More responsive but won't know postively until dyno or track.

HeissRod

So, what you're saying is, your butt is more responsive to larger piping?

Hulk

Nice try lol. not what I said.

Lol you should be a comedian! Maybe you are btw when are my pigs arriving?

XSTAR

These delete the primaries correct and need some fab work install correct?

Hulk

Yes they delete cats but you can add race cats if you wish, you don't need fab work if you are installing as is, just some welding to stock exhaust

XSTAR

Thanks. Trying to decide what to do if I pull the trigger on headers.

1- race cats
2- source another resonator

I'm running secondary & resonator delete with C63 mufflers now and its a bit raspy so deleting the primaries would likey amplify that. Though part of that may be my h-pipe vs x-pipe. Just want to get it spot on if I rework.

I have a set sitting in my office waiting to go on...

With no cats your exhaust will stink.

Rocman8

how bad are we talking about here? I'm thinking about running catless as well.

Plataille

I personally like the smell of catless exhaust =)

JoeNobody

Keep secondary cats. Very little restriction, and no stinky exhaust.

I've only been around a few catless E55's, and they stunk. A luxury car should not stink like a run down junket.

Super fast shipping & excellent customer service. Jerry answered all my questions. I just got mine installed today and I left the secondary cats & res on. I don't smell any fumes. Hopefully I can get my car on the rollers at Eurocharged in Toronto this week.
