Anyone know what typical full exhaust system gains can be expected?

I'm considering adding it to my project schedule.

 

4-5whp.
I have a Full hindle with PC3 it has given me around 4 hp

 

hmmmm 4% gain[&o]. I suppose the real gains are in weight though, 8-12 lbs?

 

-7lbs=1hp

 

Not much bang for the buck.

 

yes i must agree. It may not be worth the 1500 spent on both exhaust and pc3 for 4hp

 

i have the full tri oval from yoshi, and i cant tell a huge difference running against another f4i a little bit in the top end, but defiantly no difference in low

 

idk what my gains were...but after with cali model i got like 92.7 an like 46 torque max.

didn't seem like much at all, but weight savings was like 15lbs already and i was able to pull from a 05RR stock (i was at -1 up front too though). bike revved much better, etc. but below 5K it was a dog, hence the gearing swap.

it's a lot of bling for little gain, but if you gots the funds do it and help stimulate the economy!
