US Headers & Exhausts NA

[aka_juffa]

Yes, but you should make sure that you confirm your exact model with the seller as there can be some variation.

There are so many good options locally, why go through the hassle of getting it in from the States?

Hi.
Just remember most US extractors are to a degree compromised owing to the steering shaft on the left hand side ( the hot side )on Na & Nb and the problems with long primaries and collectors in a restricted space, You would be better off getting onto one of the buying groups and buy from yahoo japan secondhand or source locally.

Those aren't equal length. At all. You can tell by looking at cyl 1 and cyl 4. Cyl 1 should be reasonably straight to the collector, and 4 would be curled up to make up the length. You should have spent you're money fixing the current headers.

Do you even understand what tuned means?

No warranty aye.

I see these welds lasting a long time

[slug_dub]

SURE ARE CURLY.

"Product Info and Spec:

Header:
1.65" Equal Length Runners"

they have a rather broad definition of "equal length".
Primary that should be the shortest is the longest and vice-versa.

Also, how exactly does the secondaries attach to the tertiary?

Gas flow rates to the collector from each outlet. Arrive same time.

Have you looked at the pictures? The primary on cyl 1 must be at least 10cm longer than all the rest.

Don't brush it off because it is cheap and on E Bay. CX Racing has a huge range of products.

It's not that it's an ebay product, it's that in the pictures (both stock photo, and fitted picture) it's quite clearly visible that the runners are not equal length.


But, please do buy them, and when they arrive grab a tape measure and let us know the length of each runner.

The bracket in the photo Steampunk.

Bracket?

I see a set of primaries/secondaries,
I see a tertiary pipe with flexi joint,
I see a constant-torque T-bolt clamp that is designed for securing rubber/silicon hoses....

If that company is seriously telling us to attach two metal pipes that are in constant high thermal fluctuations and considerable vibration with a T-bolt clamp... that in itself speaks volumes. No?

[emily_mx5]

^ Umm what?
Not a silicone hose clamp, that's a V band.

doesn't matter what it is. its purpose is to bind the 2 sections together. it is illegal. and it is doesn't fall apart first at this locking point, then the DOT will have fun in the pit with it.

it still requires work to make it legal, ie flanges welded on replaced the clamp section, and even the still the turned length runners are questionable.

even if they were tuned length, that size primaries and length, you have to be looking for 8000-9000 rpm. and doubtfull it will drive properly under 3000rpm.

I'll do a outer diameter measurement of the cyl 1 tube compared to the others. The inner diameter of a section/s on the cyl1 should be a touch thinner but how do you know?

length of runners! not diameter.

This is great!
