Ace 4-2-1 Header

[Lynxis]

I imagine the Perrin 2.5 inch resonated will sound great and shouldn't be too loud. Maybe look at a good resonated/catted front pipe to go with it to quiet things down more if it is still too loud.

Any help understanding the differences between the three overpipe designs?

In for a penny In for a pound question, what does the Type A design bring to the table that the Type B does not?

Thanks

Thanks to awesome "beta testers" -you know who you are, the Type B is almost identical in performance to the Type A.

Hmm, I was looking forward to ordering one of your Type A headers sometime in the near future, but having second thoughts now due to the above comments, as I'm not really sure what "almost identical in performance" means. I'm sure the Type B are awesome, but all the dynos I've seen are from Type A. Really would like a header that extracts the most power and don't like to settle for second best...

When we started Ace we wanted to build a header that made 86 owners happy. We wanted people to love the sound, power, torque and have that awesome "whoo-hoo" feeling when you change gears.

CSG played a big role for this to happen, so we promised them we would build 20 final Type A's over the course of 2016 to fulfill their commitments with their customers.

We're confident that when people get their Type B's, that ear to ear grin and "whoo-hoo" feeling will come with it.

Thanks to everyone for the understanding and feedback.

happy driving
Team ACE

PS- rumor has it CSG is in development of a low-db, high-power muffler....just a rumor though...

Wait, no more Type A. It is all Type B from now?

And I certainly don't mind the wait. It is understandable since it is made in Taiwan. I am saving up for it.

Which Ace header/op combo would be best for a N/A setup? Looking to get the best header for the $$. Noticed you have the 150/250/350 as OP options to pair with the header.

Contemplating between Ptuning, Nameless, JDL UEL and the Ace header. Also waiting to see if Toda comes out with a header for the FA20 platform...

It's lighter.

It's like comparing the Tein N1 to a Tein SRC. The performance is identical, but the N1 is lighter (by ~30%)

didn't know that. they're all accounted for?

Thanks Mike for the quick response.

As to the three over pipe designs, the longer "2" pipes will do what For the hp-torque curves. Trying to figure which of the three (150, 250 or 350) is the better way to go for a daily driver that a couple times a year gets to the track.

Appreciate all your contributions to the Twin Community.

Just got word from the dynapack where I was tuned on. They finally got a stock Brz dynod and it came in at 146 whp.

ACE header + ACE OP + e85 came in at 187 whp. (169 whp on 91)

JDL uel on 91 came in at 164.

I'm trying to get an overlay from them but won't be till next week.

Well said

Technically, I am upgrading from a turbo. Albeit via blown motor to stock motor with stock header to this.

The overpipes are different because some tracks require more HP and other more torque. All OP's are interchangeable without purchasing a new header.

Short answer:
150= Highest peak HP- lowest torque
250= Middle of the road
350= Max torque and lowest peak HP

Type A= single pipe primaries and 15* merged collector
Type B= Twin pipe primaries and 20* merged collector
OP's= same for Type A and B

Talk with CSG and see if you can purchase from them. If you really have your heart set on an A they should probably be able to help out. If not, send a PM.

Dyno numbers for the Type B's will start to emerge soon. I'd say within a week or 2.

As of right now, yes.

Thanks for compliment and understanding there's a big difference between Taiwan and China

Depends on what you're looking for. Most people like the 350 because it gives you max torque. The 150 only pulls ahead in HP after 6K so if you don't track much the 250/350 is probably the way to go.

If you're still curious @CSGMike can help explain this or we can explain in a PM.

It alters the shape of the torque curve. Pick your collector based on where you want the most torque
