Default Lachute Performance Equal Length Header

Hi all,

I wanted to take a second to review my most recent purchase for my 07 STi... The Lachute Performance Header.

Backstory:
After years of driving subaru's I've come to find out that one of the best ways to make power and torque is a good quality header.

As some of you may know, I recently sold my 06 GTO and got back into an STi after a few year hiatus. During my time as a GTO owner, I was introduced to a different style of community. The GTO forum members swear by the high end stuff (doesnt everyone) because of the time involved in the engineering process, the design of the header, the steel used, fitment, and quality. Most high end header brands were made out of high quality stainless in the USA and countless hours were spent in the engineering process and construction.

Coming back to the Subaru world, my goal was to find a header like that. Made out of good quality stainless, engineered to perfection, excellent fitment and quality. After countless ours of searching I stumbled across a company in Canada called Lachute Performance that started a header thread a while ago. I read through the original thread, PM'd a few people and got some reviews from the few people here in the US running this thing. All the responses were highly in favor of this header.

I saw it wasnt made in China and it wasnt constructed out of cheap steel like many other name brand headers out there. The header was rigorously tested and dyno proven to make great power and torque. This header is made on an individual basis by hand. Someone actually fabs these things up!

The welds are are amazing and the fitment is great. It has extensions that actually feed into the uppipe to prevent the dreaded uppipe leak that 99% of cheap steel uppipes develop. It has a special flex section with a slip joint built inside to prevent cold start leakage... unlike the other major brands.

Anyways... enough reading... now for the pics:




Driving review: This thing rocks. Obviously below 3k you're going to feel a very slight loss due to the increase in piping but after that, hold onto the wheel because this thing caused my car to torque steer in 1st, 2nd, and 3rd. The torque gain is amazing to say the least. I've ran almost every header one can run on a Subaru and this thing is by far the best header I've ever installed and driven.... period. Since it gets rid of the inefficient subaru rumble, it creates a nice smooth tone like a real STi. It also quiets the car down on the highway. Since im on stock catback, my tires are actually louder than my exhaust I love it.

The only downside I could foresee is the price... I paid a little over $1400 which is definitely a lot more to spend than the average header.

Car is running great ...I must be running more rich because the tune isn't picky like it was before the install... I love increased efficiency

thanks, it really is a work of art. Those guys took the extra mile on everything...

The slip joints are specially design to prevent cold start leakage. Here's an internal pic...

Primaries look pretty big. Any measurements or specs on piping I'd?

i hate to say this but i didnt take any measurements.

Iirc from memory, the primaries were around the standard size... around the same as the other headers ive installed in the past only these were custructed 100 times better and better stainless was used.

this header is still doing great btw. best power mod ive ever purchased for a subaru... even better than a turbo upgrade

the construction on it is seriously amazing... ppower01... buy one!

I still cant get over how smooth is made my sti and how much torque it gave the car... and i still havent even retuned for the header

Thats nice to hear, Im seriously considering one of these for my car. Its funny you mention your GTO, because I can remember you talking about it years ago. I always liked those cars...great package for the money!

The GTO was like a lounge chair that hauled ass... it was a bit heavy, but for a daily with some power... probably one of the best choices...

Iv got front to back lachute system on my 05 Sti people who look at is say 2 things about it, WOW or too expensive.

You pay for what you get and I can say the quality is there. If you can afford it it's the best way to go and if you can't afford it save till you can cause you wont be disappointed

Exactly what twitch said...

FYI, the sti picked up 30-40 ft lbs of torque after he tune according to sti Mikey. He was very impressed with the header

Nice set of headers and it looks like you did your home work like one should when spending that kind of money. I coated a set of those some time ago and a set of Killer Bee's. I found myself falling in love with the Killer Bee's and said if I ever save up enough I'd abuy a set. The killer Bee's are one if the only one's who use 321 Stanless Steel that has a mix of titanium alloyed. Most all other manufactors use 304 S.S and with turbo charged motors they can exceed the temps of 304 and crack.

High Heat Retention. 321 stainless steel conducts less heat than 304 stainless steel. The short primaries and properly sized secondaries also pull less heat from the exhaust gasses increasing turbine efficiency. Large tubing headers expose the exhaust gasses to more surface area transmitting more heat and reducing exhaust energy. You can also ceramic coat or wrap the killer Bee headers (and keep the warranty) without exceeding the temperature range like you can with 304 stainless.

Dennis, I looked at the killer bees and after a lot of research I determined that the design of the killer bee was not as efficient as the traditional setup. Those headers do well because of what you mentioned above but the overall design is inferior to the lachutes. The lachutes use 321 and 304 on the slip joints.

Either way, you get what you pay for!

Hey Bud, I did look at the lachutes and thought they were one of the best out there. I even wrote a letter to the company asking about the 304/321 question. Of course I didn't have the money to purchase either one at the time :-) It's good to know that you have done your research and have a set to use as a reference of their quality. If when the time comes again I'll take another look at them. thanks,

Well, this is interesting. I fitted an EL header to my '08 WRX, which has the stock muffler (after a custom 3" resonated midpipe), and it got louder. Now I have an annoying drone at highway speeds. Too bad I can't retrofit an '07 muffler to my car!

I've heard the 08+ hatches have a bad exhaust drone. Someone needs to come out with a catback that has heimholtz resonance chambers in it.

fahr_side, I would look to add another resonator somewhere in the midpipe. Its probably straight through isnt it?

It was okay until I put the header on. I have a 3" midpipe with a fairly long resonator in it. I could probably swap a very slightly longer resonator in there but not cram in a second.

It would be great if a manufacturer would develop a CBE and tune it for an EL header, since so many people use them.

Yea, I agree. Here's a link to the resonator I was talking about it. It should definitely fix your problem.

Interesting, thanks. I'm quite familiar with tuning ported speaker enclosures and I can measure the new cabin noise frequency easily.
