I'm sure that's there's already a thread for this, but what is the best exhaust for a turbo'd 8? From what i can see most people with the same set up as me (I mean same PSI, turbo, and all that), just with differant cat-back are running a little more hp than me.Right now i have the greddy sp2 and i want something better flowing if possible (and more JDM'ish). I really like the JIC titanium exhaust but i don't know whether it actually preforms better than the greddy. I'm also upgrading really soon to a much bigger turbo so i want the best cat-back possible. Any suggestions?

 

i would reccomend a single outlet exhaust. The hks single outlet made more power than an average aftermarket dual exhaust:

yeah that's what i was thinking but i didn't really want a to have to go and modifiy my bumper, but it is HKS and HKS is well...friggin' HKS (maybe i should just get it)! lol. What site can i get it off of?

 

i htink i read somewhere that the borla made actually made some hp. but very minimal. but if u are going for turbo, i think u should go wit the hks single outlet exhaust.

 

it's listed for $520 on their website.

just choose your location and it will find the closest authorized dealer.

as far as modifying your bumper...it's an easy 45 minute job...nothing special

 

The HKS is definitely the way to go for Turbo guys looking for a good exhaust.

 

well the problem is that my rear bumer is the veilside d1 kit, so it might look a bit odd even modified. but i think i can live with it considering that it's designed for turbo'd cars.

 

not to mention the weight savings!

 

you could try turboXS. supposed to be good stuff especially for tubo'ed cars.

the hks single would probably be best, but if you still want to have two tip.

 

Custom job....

 

The TurboXS exhaust is great for a turbo'd car. It is a very free flowing, full 3" exhaust.

 

the tips are a bit funky, but they are on sale now at turboxs web site..

beers

 

hks hands down, its just an obvious choice =P

 

any sound clips?

 

uHm... on the hks website it says the single exhaust is for turbo application im just wondering is it not good for n/a? cuz after seeing XDEEDUBBXs video i've decided to get the hks single exhaust :D and im actually planning on to go catless

The HKS exhaust is also a "true" full 3 inch exhaust.
thats going to be loud! haha make sure u run a resonator, you'll need it!

 

so the HKS single exhaust is also good for N/A car rite? cuz the weight and for duel there's that almost 90 degree bend but not as bad for single rite?

 

there's nothing wrong with the single sided exhaust for NA cars. There's just not a whole lot of performance gains that will distinguish the standard legamax exhaust vs the single outlet. But the sound is kick ***!!

 

yeah i figure any exhaust i buy there wont be much power gain and the hks hi-power is lighter and not that many ppl has it. AND it's cheaper LOL

 

How a single no bending no splitting exhaust is similar to performance with one that has so many restrictions(like the design-fashionable ones we see on many 8's)?

I saw and I felt a noticeable difference in performance when I dumped the Trust PE Ti and installed my custom single one and all that before the HKS hype.

 

For an FI car, the bigger the better

 

That's a fact, but works also in a N/A car. That's what I'm saying. Flow is the key, I believe.

 

For FI, without a doubt.

For NA, I don't think your gains are significant enough to matter much. And a big 3" exhaust would also lower your torque.



It's going to be stupid loud. But depends on exhaust. HKS wasn't very loud with a catless, while borla and catless (with resonator) was unbearable when NA.
