nothing wrong with a good replica... I've had a set of gruppe S headers on my car for over 2 years now wrapped with no issues at all... if i want to go with equal length headers i would have no problems going back to them for another set.

the synic set i think can come coated, and they have a warranty on them (even if you wrap them) which is damn impressive if you ask me.. shows they are sure of their part. If i were in the market, and might be after i get a few other more expensive items out of the way for my car, i might find myself ordering one up from synic.

im on the same boat as the OP... im leaning more torward the Synic because im getting a good deal, but the perrin is also proven.

BUT!.... PERRIN is known for its raspiness... synic, not so much.

i've seen a couple of threads about PERRIN's headers making the car more tincan-ish on the higher RPM's.

I think I've made my mind on the headers... its Synic all the way!

Between those two choices, the best is gonna be the Perrin, but take a look at the GTSpec Gen III, for the same price, I think it's a better unit.

the bends on the Perrin are less severe and the collectors bring the gases together more in-line so at higher flow rates, it'll be more efficient.

is there proof of this and is their dyno charts to see if it makes a diff? i just looked at the gtspec gen 3 and its a nice piece for sure! does it include the up-pipe? im not trying to argue im just trying to do some research before i commit to buy because 600-700 is alot of money..thks for your input nhlur!

I've been through the Indivia EL, Cusco header, and Perrin EL. The Perrin piece is so far the best I've used. Its also the only one that I've used that is sub $1000 well before ceramic coating that is. Cusco (non-EL) gave power in the mid powerband. Perrin and Invidia (EL) puts the power up top. Cusco was louder than both the Perrin and Invidia; some ppl like it that way, I don't. Invida could have had better fitment especially around the uppipe. Perrin could have better welding and needed some cleaning up at the inside welds. Cusco had a great idea of adding their own heatshield but couldn't pull it off because many (not all) had their heatshielding fall off after some amount of usage. Header modifications shine when they tuned for.

I doubt there are dynos to show that the Perrin is better than the Synic, but if you recall the old SpeedStyleSound header comparison, the Fujitsubo header (which this is a direct copy of) had excellent low-end torque but not the greatest upper rpm power. Likewise, in the recent comparo conducted by Rainmaker (linked in the sticky for this forum), the Perrin showed better torque/power everywhere than the other headers in the test. It is just common knowledge that less extreme bends = better flow.

The GTSpec does include the uppipe and comes in a variety for either the JDM twinscroll or USDM singlescroll.

Have you looked at the Gruppe-S header? It is 4-1 design, investment cast collector, SS304 with TIG welding, and works with the factory uppipe. In our testing there is very little additional gains by going equal length - reasons being the exhaust pulses end up colliding in the uppipe on a non-twinscroll setup anyways (twinscroll turbo is a different story). Furthermore I am fairly comfortable the Gruppe-S header costs less than half of what the APS does

Cheers,

Gary

In this test, the Gruppe-S header (with coating) is the red line and the Perrin (without coating) is the blue line. Looks like a very healthy advantage everywhere in the rpm range, to me.
