HKS TI Cat-back + which high flow cat and downpipe?
I know that the HKS TI Cat-back is 3inch but tapers down to the stock cataltic convertor. Does that mean that the APS 3inch high flow cat won't fit right?

Also should I get a downpipe with a flex section or is it not that important.
I was looking at this downpipe for my IX

Thanks for the help.

3 2 1 (prepare yourself)
It depends on how much you want to spend.
Tanabe makes a great dp, and you can get a cat-delete from pretty much anywhere.

It doesn't matter as long as the parts are flanged. It's the pipe that tapers down, not the flange itself. You can get whatever HFC and DP you want, but the downside is you will have spent about $1100-1200 on a full exhaust that doesn't make much power - that's gotta be disappointing.

I have the DC Sports dp/tp with the HKS cat back. Fitment is perfect. Although you may get flamed as the HKS is not the best power mod. But it does make descent gains and looks and sounds great.

Agreed, but I got a great deal and did not buy it brand new.
I want an HFC to keep it street legal, cops do check in my area and I don't need the hassle.
Thanks for the info.
Since the HKS tapers down right at the flange can it affect power that much?
Warrtalon for the used HKS Carbon TI cat-back $450
New HFC $260.......Used $ 120
New DP $300........Used $150
So between $1,010 and 720
If I can stay around $800 for a full exhaust system I will be happy.

HFC is not street legal - it's still a federal offense to remove the stock cat. Common misconception by many. If you get caught, it's just as bad as a test pipe. However, you can pass visual inspection and usually pass emissions tests if that's all you care about. No, the neckdown isn't a big power loss, but the cat-back doesn't make much power in the first place. It's usually 10-15whp with a full 3", so your neckdown cat-back is probably closer to the 10whp range, and an HFC will make less than 5whp over the stock cat.
$800 is what you would pay for a brand spankin new BR TBE, and you can choose the HFC option. It's good you got the TI used, but it's still not worth that much when you can get a more powerful cat-back brand new for less. Hell, my entire Megan TBE I'm selling for $400 used. Anyway, personal preference, etc, so it doesn't matter.

Wow I did not know that, thankyou.
I was looking into the BR turboback exhaust, but to be honest "Flame Suit On" regardless if the HKS will cost me 1-3whp I like the look of it.

I can't see my exhaust, so "looks" don't matter. AFter a few months of driving, it gets covered in durt, grime, and soot anyway, so I go with what makes the most power for the least money without falling apart. I also don't like huge fartcan 5" exhaust tips, but if I was industrious, I could have welded a different one on to my previous Megan TBE I'm sure...

"without falling apart" The HKS better not fall apart. I ran that system on my 1988 300ZX Turbo and my 1990 300ZX Twin Turbo without any problems.
