I tried searching but with no luck.. How much whp does this add to a stock g?

Also, from what I am reading about this, the exhaust seems to be very quiet? I was hoping for an exhaust to remain relatively the same under 3k but hopefully above that or at WOT, it be somewhat louder and noticeable.

 

Installing an aftermarket y-pipe might gain you 2 RWHP but they're not worth the cost! Gains can be found by installing high flow cats (HFCs) the main restriction is in your OE cats....and you'll be legal in most states. Are you asking about the Fuji intake, no they don't come with a CARB number/sticker....it's pending like it has been for years.

no i am mentioning about the fujitsubo legalis exhaust not the intake. Just wanted to know how much hp i will gain from the exhaust and a ypipe.

 

Exhaust will only give u between 10-15hp gain. Dont buy Exhaust for Horsepower and Torqe gain. You will not realize anything performance wize when u put on ur exhaust. Exhaust will just basically make ur car sound cooler.

 

wrecko, i hope you are talking about personal experience. I am not sure about the g35 but when i installed an exhaust for my integra back in the hay days, I did feel a performance gain and no it wasn't my mind playing tricks on me.

 

anyone know?

 

You do realize you just contradicted yourself right?

 

Might check in the exhaust section, sorry but I don't have a clue.

 

not much gains from a cat back exhaust on our cars, just sounds awesome.. As garyc said, go with HFCs or resonated test pipes if you're going for a hp/tq gains. One of the best bolt ons for our cars imo.

 

i;m trying to stay away from that raspy ugly sound. i know resonated test pipes have better flow than HFC but do the resonated test pipes sound a lot "uglier" than HFC.

 

wasnt there a guy that dynoed the hr y pipe and it added 10 hp?

 

Don't do anything n/a for power gains bc you will hardly notice it. Do it for sound and the thrill of new parts to install. Been there done that and I wasn't impressed.

 

HFC give you a raspy sound? Will HFC bolt up to the stock exhaust or do you have to go aftermarket?

I had thought about the fast intentions HFC a while back to but held off so im curious on this one myself

 

HfC can rasp depending in brand. Yes, they can bolt to Stock exhaust.
