I also have a few questions Gernby. Is there a particular exhaust (besides your custom exhaust) that will get the most out of this unit? For example, will I see any noticeable gains from switching out the stock exhaust for say a greddy se dual? I plan on keeping the stock exhaust and header for a while, but just curious if it would be worth getting a greddy and live with the additional drone to potentially get more out of the gern-pipe. I'm sure you answered this question but couldn't find the dyno plots through search. Also is there a particular tune that works best with gern-pipe + stock s2000? I think you mentioned something about vtec at 3600 but can we expect the same performance if vtec was engaged at a later point? I wish we could get some more feedback on previous buyers. ..Last but not least, any idea of pricing for this production run?

 

In for pricing aswell.. would love to hook this up to my js exhaust

 

thanks for the reply gernby. how hard would the install be? if i end up buying one i'll most likely take it to a shop and just want to get an idea of what kind of work to expect.

 

I haven't finalized pricing yet, but I do believe it will be a bit higher than it was for the first 6 units, which was $1100 shipped and paypal'ed.

The install would be simple for any exhaust shop. If you are retrofitting an existing exhaust, the installer would cut the exhaust a few inches behind the rear axle, then replace the front of that exhaust with the mid-pipe. After inserting the provided spacers above and below the midpipe, the installer will adjust the 2 V-bands on the midpipe to achieve optimal alignment of the output, so that it lines up with the muffler section. Then he will cut a short pipe that wil be welded between the midpipe and muffler section. Or he could put a 2-bolt flange there.

 

So.. How is this compared to a 70rr..
Besides alot quiter, n wont cause shit to rattle.
I want one.. But the hfc isnt for me.

I read the entire thing btw.. I must have some 200 emails from this thread..

 

The 70RR is a full exhaust, right? If so, then it can't be *compared* to my mid-pipe. However, if you want to know how my mid-pipe would *improve* the 70RR, then I would say that it would 1) increase midrange torque, 2) reduce drone, and 3) reduce odor.

Unless you know of a reason to NOT have an HFC incorporated that I haven't thought of (during the 17 years I went with a test pipe), please share it. Now that I've discovered a way to impliment an HFC without costing ANY performance, while also improving sound, reducing smell, and being legal, I can't think of ANY reason to say "the HFC isn't for me".

Did you place a big bet with someone that you would never run with a cat, and you just don't want to pay up?

 

thanks for the installation tips. just wanted to clarify, but you said this works best with the stock header, correct? i think i read somewhere that aftermarket headers will hinder performance

 

Most definitely depends on the header. Theres alot that do give you SOME gains and then there are some that will definitely wish you didn't buy. Ive been told the stock header is actually pretty well designed but it does weigh a bit which is why most people replace it.

 

I look forward to these results as well.

 

thanks. just read through the thread and saw that the gern-pipe only bolts onto the stock header. gernby doesn't reply to questions that have already been asked lol.
