Help me choose the right downpipe HKS vs Megan Racing
So... I have what looks and weights like an HKS 3inch downpipe vs what looks and weights like an ebay SS downpipe.
HKS: Picture # 1.
It weights 10.5 to 11 lbs
Mild Steel
3in inlet and 3in outlet
Generic (MEGAN RACING) Downpipe: Picture # 2
It weights 5.5 to 6 lbs
Cheap Stainless Steel?
3in inlet 3in Outlet.
I would like some feedback regarding what you guys have used and what you would recomend. My car sees approx. 150-200 miles a month and 2 autocrosses. I run in ASP.
Im looking for reliability first and power second.

If I was you I'd go with an LHD aftermarket one. All the JDM brand names are designed for an RHD car, therefore are restricted size/flow wise as they have to be smaller to fit past the steering rack on an RHD car. You'd get better flow off a DP that uses the extra space in an LHD to its advantage 
.
Also mild steel & double the weight isn't ideal..

If you're going to use a JDM pipe, get a FEED, Revolution or Maxim Works. The FD deserves better than mild steel imo & these three pipes are larger diameter, therefore less restriction.

A smaller diameter (In places) exhaust with more curves flows just as well? Not to mention the sharp exit angle...If you say so

FEED etc.... are all over priced JDM fancy pants parts hehe and don't flow as well as the M2 which is the only true 3 inch flange to flange DP I know of
Back to the question at hand megan VS HKS and HKS takes it with ease. It's mild steel, it's heavier and it flows less BUT the build quality is excellent (thick piping, great fit, THICK flanges and it's nice and quiet) and you won't have any issues installing it or exhaust leaks after 10k miles. Bottomline it's a great street DP

YEP the HKS does restrict flow but not enough to worry about unless you're building an autocross car and need every little bit of power and if that's the case go with the M2 pipe my favorite...............but good luck with the installation

Regarding the pricing, they're all pretty cheap & similarly priced over here, I wouldn't know US pricing
- You'd pickup a FEED pipe for $160 here.If you are limited to just those two options, I'd also take the HKS. But if I was buying a DP myself, I wouldn't buy either

I agree with you, was just pointing out there are better solutions out there, push for greater & all that

I agree any of the JDM pipes with the flat walled pipe would restrict flow so no arguing that but in this case the build quality trumps the flow in my opinion.

As mentioned above, I like the bracket at the downstream end....which the HKS and some others have. It mounts to the transmission housing. Without it, everything is suspended from the DP/turbo flange bolts to the first hanger which IIRC isn't until you get to the upstream end of the cat-back. IMO that's alot of weight and a big span, And I suspect that much harder on the flange gaskets at both ends of the DP over time.
