my last thread was deleted because that one guy started a group buy on my thread and jacked it up. DO NOT POST GROUP BUY ON THIS THREAD. If it gets deleted again just PM me for dyno results.

This is my review thread on the 1320 Performance Header. I will be doing a back to back dyno comparison with stock header, 63.5mm TP and Tanabe Medalion Touring CB as the baseline... Then swapping to the 1320 header and doing another set of dyno pulls. Stock tune on both. Hopefully I can get a good AFR reading to see where tuning might be able to yield more power. Will dyno in a few weeks since I live in Michigan and theres still a bunch of snow and SALT on the roads.

The 1320 is very much like the HKS header (4-2-1) with some notable differences:

Number of O2 Bungs:
1320: 2
HKS: 1

Piping Diameter:
1320: 45mm-47mm-54mm-63.5mm collector
HKS: 45mm-50mm-65mm collector

Weight:
1320: 12.5 lbs. +/- per my crappy house scale
HKS: 10 lbs.

Heres a link to the 1320 Performance header:

Below are pictures I took from 1320's site

 

Pics Cont...

 

So according to 1320 Performance, The header heat shield can be used but you have to bend in a portion of it to make it fit, and the black heat sheild can be used with some trimming on the bottom (shown in pics below).

 

I ordered the header and it took less than a week to get to me. Here are some iPhone pics I took of mine. The welds look very good and the brushed finish is a nice touch. It came with the gaskets and two nuts and bolts shown below.

 

Now let's see how it runs on the dyno...fishy they didn't provide a dyno sheet to begin with, granted most dyno sheets are BS but they didn't even bother with one.

 

Yeah I hope it makes power

 

So you bought this without any Dyno plots of any kind? What reason do you have to think it performs as good as stock?

 

Just hoping that it is a viable budget header option. We will see... At the very least this might serve as the first dyno plot for the community. If it makes power, great! If it loses power, then this will let people know. My attempt at trying to contribute to s2ki I guess

 

Before and after on the same day or it's worthless info

 

Lol. Unless there's a huge weather change I think he'll be okay
