So I'm surfin around youtube and come upon this http://www.youtube.com/watch?v=LFOXUF9v2j0 After checkin out the website and then chatting with the guy on aim I found out that he just did it for personal use. Has anyone seen anything like this from a real exhaust company?

 

uhhh ya i have 1 very similar to that, guy on here made it for me. i love it and want him to build me a header to compliment it

 

that looks awesome i would love to have that same exhaust how much and from who? and is he able to make the headers too? email me marie_rose1983@yahoo.com thanks

 

Does it really add performance, or is it just called a "performance exhaust" ? The slight loss of backpressure might actually hurt your overall power output. I would like to see it dyno tested.

 

It looks cool, but does it sound good? It seems to me that you might loose so low end with that set up.

 

what with the tin-foil?

 

I waslookin into gettin my exhaust setup like this. I am still very interested. Is there an actual brand that makes them like this for F4is?

 

that far back i dont think that it will affect backpressure that much.
although the less pressure the better as long as it doesnt slow down gas velocity.
i would still get it dyno tuned though

 

lol been awhile, k there no backpressure lost with it, javier designed it so it wont hurt the engine. ive been riding it for 3k miles and its still runnign good with no bad side effects. honestly it sounds really good, nice low rumble for just moderate cruising but she roars when you get her WOT. you dont loose low end with it at all. it honselty feels more responisve with this one thanthe akra i previsously had on there but that may be from the pcIII. the tin foil was on there cuz im workign on a custom seat cowl. i honestly forgot how much i payed it was liek 250-300

 

I'm currently rebuilding my 02 F4i and am definitely interested in this exhaust, can you get me a contact for the person who made yours please.
