Been searching for an exhaust. Really enjoy the Two Bros exhaust. Their site says that there are differences between the F4 and F4i exhaust. I am curious, will the F4i VALE system still work on the F4? I've heard something about the o2 sensor, but I'd like some input from those who may have the F4i Two Bros system on their F4.

Any help is appreciated!!

 

The f4 and f4i headers are different. You just need to plug the o2 sensor hole. I'm a fan of yoshimura, akrapovic and of course Jardine

 

Thanks for the info. Of those that you've mentioned, any recommendations or one over the other you'd personally get?

 

Jardine, but it runs in the family. You will find Yoshimura all over ebay with a few Akrapovic mixed in there. The jardine is rare as all hell for the F4. I would recommend calling who every you end up going with, they might be willing to sell you one for cheaper than ebay. because it gets them another sale and they can clear old stock out of the warehouse. Or if they are really cool they will just make you one. No promises. Oh and if you really like two bros you can check out D&D. However I haven't met a single person who was not in love with their Jardine, Yosh or Akra.

 

I love my Yoshi.. had one on my F4 and now put one on the F4i. The cans are the same, its the inlet pipe that makes a difference.. but trying to find an F4 inlet pipe will be next to impossible... scour ebay and classifieds for a good F4 exhaust.. 2bros has a great sound to it as well.. they all really do.

 

I appreciate the info fellas! I'll do some searching around and see what I can find.

 

I have a Yoshi Tri Oval CF exhaust. Its high quality & sounds great. Not cheap.

Any of the previously mentioned are good choices. I've met the TwoBros factory reps. They sell a great product. Give them a call & ask them the questions you have. I'm sure they'd be happy to talk w/ you. Two Brothers Racing :: Customer Support

 

D&D ALL THE WAY!

i love being heard ripping it from far away (except in cops ears xD )

 

Thanks everyone. I've been searching today. Really like the cf look (who doesn't??) but realizing I don't necessarily need the look for 70 more bucks than the aluminum. I'm gonna keep hunting!

 

I love my new titanium one. It's a strong contender to the cf. Both the aluminum and cf are shiny with the ti being a matte. If you can find a midpipe for the F4 that has a 2 1/4 inch outlet to the exhaust ill send you my old one if you pay shipping. I don't really have a use for it and its just taking up space. It's pretty beat up though. I bought it used and the previous owner put a bit of rash on it. If you wanted to cut it down by two inches the rash would be removed. That was what I was planning on doing until I called and got the new one.

Hey turb or gotcbr can you guys measure the OD of the yosh's midpipe? Still on the hunt for headers.
