I have posted a lot about my plans for a custom exhaust setup lately, and I've decided on the HKS Universal Mufflers. Now I need to decide which ones... There are 3 options, each with 2 sizes

Hi Power Stainless Steel 130mm $480
" " 170mm $520

Hi Power Ti 130mm $534
" " 170mm $572

Hi Power Ti wrapped in Carbon Fiber 130mm $595
" " 170mm $591 (yes I know it's cheaper than the smaller, I found a really good deal)

What are the benefits of getting Titanium? Anything with sound? Also, for only $20 more I'm getting it wrapped in CF, so really I guess it should be between the SS, the Ti 130mm, or the Ti w/ CF 170mm.

Any and all comments are welcome, I am set on doing a custom exhaust, I appreciate the warnings but I really want to try. Thanks.

EDIT: One last important question. On the back right side (looking from behind) on the Z there is this annoying little box that will prevent a straight on exhaust install, for those of you with aftermarket exhausts you know what I'm talking about. I'm pretty sure GReddy moves this box with their system, so that you can, but I want to be more than pretty sure, I want to be 100%. Can you indeed relocate this box to put on universal mufflers with tips? Thanks guys (and girls).

 

my only input in this is reguarding the box you mentioned. it got in the way when we were installing my pro-1 exhaust. just unbolt the cover. you mihgt want to take some thermal wrap and wrap the hoses if you are concerned with them overheating or being damaged. i just left them as-is. so far, about a month and a half later, and a full day at the drag strip, they are doing just fine.

 

anybody have an opinion on this? im really torn between the two tip sizes...

the 130mm canister has a 96mm tip, which is 3.78"
the 170mm canister has a 120mm tip, which is 4.71"

 

I've heard a custom dual HKS carbon Ti 120mm tip and it was by far the sickest sounding exhaust I've ever heard for the Z. The tips were a little big IMO for a N/A car however. Check out Ebay for pricing...I've seen the mufflers on there for 270 each.

 

were the tips pointing straight back or were they angled? i am worried that the mufflers wont fit...
