I bought a used downpipe(no idea the brand) and RX7Store resonated midpipe but I'm not sure what to get. I really like the look of the dual tip but I'm not sure if it's so good due to the fact that it's main construction is steel.

Has anyone had any rust problems with the N1?

On the other hand, I really like the HKS Hi Power for it's price and sound. It's very affordable and does exactly what I'd want it to do.

I guess to end this, what are your opinions on them and why? Single vs Dual Tip? Which will sound better? Which will look better?

 

N1 duals are loud and sound like ****. If you want the dual tip, get the racing beat dual exhaust. Great soundinf exhaust and looks stock.

 

The N1 dual is single handedly the WORST exhaust for the FD. Fits terribly (it will melt the black plastic on the bumper), sounds terrible, and is also insanely loud.

Most anything else you can put on the car will be better.

HKS makes a nice exhaust, I had one once and it's well built and sounds good.

BTW I've owned and installed around 30 different cat-backs.

N1 singles aren't much quieter but agree on the duals

 

It seems the HKS Hi-power is also constructed of mostly what appears mild steel?

 

on the hks site, it states its made of complete stainless. I could be wrong but that's what I read

 

IIRC, this difference is between the Hi Power and Silent Hi Power. I believe the Silent is all SS.

 

Is the one that RX7Store offers a Silent hi power or hi power? And what's the difference?

 

Should be the "Silent Hi-Power" as this is the one HKS lists for RX-7
