Tegiwa intake comparison/test

[SKINNIE]

F.y.i the cf inlet pipe is an additional cost

Yea I figured. Only pics I saw of the intake was with the stock inlet installed. This should be around the same price as the Eventuri intake box + inlet pipe.

That Infinity Design CF Intake looks gorgeous

I don't see how when people are happily spending the same (or more) for a poorly made exhaust system that sounds awful. And you'll get a fraction of the 15-20hp/tq you'll get from an intake. I recall one of these shop cars lost power with the addition of an exhaust.

the folks at borla were told me there was power loss when they were trying out 3" pipe on the FL5 so they stuck to 2.75" (and did the same to the DE5).

Funnily enough, he candidly said they should've just gone with the 3" anyway because that's what the market wanted regardless.

I would have hypothesized that it would no effect. Most of these exhausts do nothing but make noise and some weigh the same as stock, so no savings there. The only benefit of an exhaust may occur when paired with an upgraded turbo. Honda OEM exhaust performs excellent out the box.

Would be interesting if you found out the reasoning on why that happened to the Borla

not sure, maybe backpressure? Anyway, it was just brought up when I was chatting with one of the engineers there when I took my DE5 to be a test mule for an exhaust.

it would be interesting if they had an answer to why. Turbos I thought needed as little backpressure as possible, but NA cars need some.

not sure. he kind of said it in passing. I was there to pick my car up so the convo was mostly on that.

Here's a pic btw.

Interesting to note that they stayed with the uneven tips that's currently on the FL5 system.

Yeah I agree and I call shenanigans on the Borla person, some people talk out their a$$ to act like their product is better. Either way it’s nice to have more vendors in the space.

This makes sense because the Magnaflow exhaust is smaller than 3 inch diameter as well.

No cars need back pressure, including NA. Yes, NA cars benefit from correct header primary and collector length to tune reversion based on valve events and where you want to make power torque or horsepower / low or high RPM but that is NOT backpressure.

Turbo cars make more power based on minimizing resistance to spool so no exhaust is best.

I don't know guys - the backpressure comment was just me guessing.

All he said was that when they tried 3," stock, the car lost power but they also went 3" for the HRC car.

I'm an accountant, he's an engineer. I just nodded my head, said "oh cool" then "thanks" and took my car home with its free exhaust.

For sure man, I wasn't directing anything at you personally, just putting that out there for whoever.

Stock exhaust flows pretty well. The dudes in Puerto Rico are pushing 550-600whp through the stock cat back.

This is a long age debate. The turbo builds all the back pressure. And once the car is tuned and moving more air it will need the least restrictive exhaust to actually breathe efficiently.

They would probably make more if they upgraded the exhaust.
