What a great exhaust!! I don't know if it was worth the price but the sound of it is amazing! I never liked loud exhaust so I'm very glad that I got this one. It's not as loud as the Racing Beat either (like mikeb said), just with an aggressive low rumble, but a little louder at higher RPMs. But there's one problem, the exhaust shop that stuck it on, made one of the tips stick out more and hang a bit lower than the other side. I asked if they could fix the hangers or anything because it shouldn't be like that, just because it was made for our cars. He said no, the hangers are titanium and he cant do anything. wtf?! It's not *******! So I got pissed and called VividRacing, they called JIC, and in 30mins they called me back. They said the shop needs to adjust a few bolts and it would of been fine. What a crappy *** shop. I'll take it back tomorrow though. Here's one pic for now because my camera's battery died. :p


you can see the tip sticks out an inch more and hangs about half an inch lower


matches the paint sorta (i know i did a bad wax job)

 

Are the tips there blued from the heat? If so, that's pretty cool that they match your car's color perfectly.

How much did the exhaust weigh btw?

 

nice! it probably hangs lower since the tips get hotter due to the single layer design, dont want to melt that plastic

 

no, the tips are blued from the factory, 'cause this car isn't serious enough to actually blue a chromed exhaust tip as it is (without some serious effort).

 

Most likely it would have gone golden yellow if that's the case... the other exhaust tips have gone yellow. Like Greddy's..

Looks good though, I like this exhaust.

 

Oh no..... co-ordinating exhausts tips with car colour! LOL

Seriously, looks "different", not really my cup of tea though.

Prefer my "self made" gold tips.

 

That is a titanium tip... it is mean to look like this.

Sweeeeeeet. That is what I have to say. Really nice.

If you put sound clip there, I will drop dead.

Tell me how it sounds after 6 months OK?!

 

ooo, finally something different. I believe someone else posted with a titanium exhuast too this must have cost you a bundle. That sucker must be light! But isn't there a durability issue with titanium exhausts?

 

Yeah, it cost a lot money about 1300. Nothing but the best for my baby! It is a lot lighter than stock about 10-15lbs difference. Titanium is a lot more durable than stainless steel, it doesn't bend as easily.

 

That blue tips looks too cool. I have a blue RX and it would look good on my car.

 

Is it worth it in terms of making significant rear-wheel horsepower? I wonder what the magnification is if you add forced induction, or nitrous oxide.

working om my Prices for all the Exhust. what do you think..
I am going for the JIC Tit as well

 

Would it be possible to get a sound clip? JIC claims 12whp is that acurate you think? I havent found a dyno. If it is that is awesome losing what and gaining some good power! :D

 

No this is not realistic. Pretty much all exhausts for the RX8 give you about 2-3 hp. Racing Beat did a dyno on a straight-thru exhaust (race headers, midpipe and no mufflers) and got about 10 hp. Many of the exhaust claim 10 to 12 hp from the cat back alone, but when put on real dynos by poster on this board dyno about 2-3 hp. Titanium exhausts are nice, but in this case if you are looking for massive hp gain, that is unrealistic. It does take off about 30 lbs. of weight though, that is probably equal to if you added 3-4 hp.

 

always take what is said by those trying to make a profit with a grain of salt... the only real way to know is a before and after dyno on the same car at the same time. this i've never seen.

while i highly doubt 12whp from exhaust alone, i also doubt that the max possible is 5hp

 

ehh....

Not with what I have seen and heard from my mechanics who has 30 years of experience. It will rust and last 2-3 yrs usually. There are 4 shops that sells Ti exhaust that said that.

It may be 7-8kg that you saved... I have 7-8 kg around my waist that I can get rid off too!

EDIT: ti looks and sounds so nice that it is out of the world but I doubt it will be like that in a few years. --- you might want to change to another car by then so... doesn't matter lar.

 

I wanted to comment on the issue of titanium. I don't think the exhaust system is made of pure titanium. It's probably an alloy, most likely of a Ti-Al type. Pure titanium probably has more of a tendency to corrode. My belief is adding aluminum into the matrix further strengthens the material, as well as add some corrosion resistance.

Stainless steel may be a bit heavier than titanium alloy, but it features excellent corrosion resistance. It's also easier to weld.

Neither material is better than the other. You need to also consider how well heat is transferred away from the engine via the pipe and the surface. A three-dimensional heat equation can solve that. I'll also throw in Fick's laws of diffusion because I'm an ***.

Hope this puts things in perspective. It's a nice exhaust oxy2gn. Nothing but the best for your car.

 

Understood and agreed.

 

While I can see why people would want to inflate hp #'s to sell products, why would people want to under calculate them ? I've never heard of a company saying they make less hp than everybody else, and expect to sell more of their product. Many of the people here who have dynoed the cars with Racing Beat, MS, Greddy, & Borla have pretty much all proven that the cat back exhaust adds only a few hp at best. I believe RX8 owners on this board far more than what the vendors have to say. But I believe Racing Beat quite a bit when they say that an exhaust is only good for about +3.5 hp. Their claims are far closer to what people have found later when they dyno their own cars. Just curious as to why you think there is more than 5 hp to be gained ?

BTW,

The standard RX8 exhaust is 17.4 kg (about 38.25 lbs.). JIC is claiming their titanium unit is 4.1 kg. (or about 9 lbs.) for a total saving of about 29.25 lbs. Pretty good. That in itself is equal to about 1.5-2 hp (on top of the 3 hp gained). Weight savings is always good, just are you willing to pay the price for it.

 

WOW

I just stop eating the dessert in front of me. :p I am going for a run now

There is my 3hp :D

I thought weight saving is only criticial in push bike.

 

well those numbers are posted by the MFG. so who knows where they come from..
I think its more about tastes and sound..

 

yea, imo opinion most of the performance improvements are from the weight reduction. 1300 dollars, thats a set of coilovers

 

yes.. but i am looking for a diffrent melow but not to loud Note !...

That is a mental Performance upgrade that i will hear all the time..
And yes.. Coilovers are just as important if not more... But thats if you really get out there and drive you 8. Most peeps can olny drive back and forth to work ..

 

The JIC is a sweet exhaust dude, the blue anodized tips matches great with your Blue 8.

 

what is the difference between the JIC Magic Spartan DE Type 2 * exhausts and the one this guy has?
