So Berk's HFC is fits perfectly to the stock exhaust?
Where can i order?
Thx!!

i'm just trying to point out from the previous poster, that how does anyone really know what the "best" exhaust setup is unless they've actually tested all of them?
most consumers do NOT know what the best product is because most consumers will not go out and buy every product and test every product.
most consumers, including myself, will buy a product they research and then justify why it is a great product because they just spent a lot of hard-earned money on something...
even with something like dynamat, how do you know what the best is by just trying the product? unless you do actual testing of all the products, you just can't say stuff like, "this is the best exhaust system because i tried it and it is custom"

NO
Without lots of R&D you cannot PROVE which is the "best."
However, making more power with exhausts is simple. More flow, less bends, less restriction.
Custom work does this...... for much less $$. Can I guarantee or prove that muffler shop X will make the "most power?" Nope. But I can guarantee that it'll make comparable power and cost way less. (from history of every car ever.)
FWIW, the VQ's exhaust is no more "sophisticated" than an '84 Geo Metro.

No exhaust shop will custom your headers. They only do from the down pipe to the muffler. And by "expert" I meant they have lots of experiences and the know exactly what they are doing. You may trust companies with their rip off products but I don't. For example, cold air intake from Injen runs about $550 while I can make the similar intake myself for less than $100. I myself want to spend my money wisely and not wasting any buck out of my pocket. A pair of catalytic converters for $500+ is a damn waste of money to me. Sorry if I hurt someone's feeling but it is true. Why don't you guys just buy a pair of Magna flow CAT for $150 and call it a day ?

I try to talk people OUT of buying expensive catbacks and exhaust sytems all the time. If you care about bang/buck and sound, skip the catback, do a muffler swap. It'll make similar power (within a couple hp, unless you seriously mod the car) and sound the same.

when i used the term sophisticated, i believe i used it to describe ENGINE TECHNOLOGY

However, Engine technology has nothing to do with what we're talking about. I was just pointing that out.
The only part where engine technology is involved with exhausts is with the feedback from your front o2 sensors that help determine A/F ratio at part throttle and cruise. However, o2 feedback is ignored when an engine enters power enrichment mode (higher rpm and throttle positions) so it will be completely neglected at full throttle and have no affect on HP gains on a dyno at full throttle.

If you're opening your hood at car shows, I don't know that they'll be impressed with your homemade intake.

cost-effective exhaust = least restrictive + least back pressure + highest flow velocity of the exhaust gas
but how can you keep saying BEST. that's my only issue...i do understand that there are other cost-effective ways to make ur own exhaust and it may outperform another exhaust product...but like i said before, you can't just throw around terms like "best" because you don't know if it really is period

You're asking for works cited and saying you're not getting "technical?"
Please go back and read what I wrote. I never said, "expert" or "best."
I'm only talking about bang/buck. That's it. I did note that on my last car custom work made the most power.
I also said that you may lose a couple hp by going "cheap." (NOT THE BEST!!!!)

He's trying to speak very generally about exhausts. And generally, what he mentioned, makes more power, and is "best" in that regard.
"Best" could mean many things. Like some catbacks are stainless steel. Is that the best? (it has nothing to do with power, but it's expensive).

secondly, i never asked for any of your works cited. i was just saying how you need evidence of your writings sometimes, similar to essays. you're the one telling me to go back and read when you can't even decipher simple analogies like that?
