Here we go with another "lean" question, with the hmf utility slip on I run lean(no programmer), with this mod do you think I will? My PC3 took a swim and I'm saving up for the MSD but I would like to do this mod in the meantime.
 
I was wondering ........ what actual gains is there to be had other than sound? Another thing will I have to re-jet seeing I have a K&N filter (supposedly allows for more air flow.................I see no REAL improvment over stock)?

Most have said they noticed a slight increase in power. You should not have to re-jet. I havent read of anyone else having to b/c of the stock exhaust mod.

The "REAL improvement" is getting a decent sound out of your stock exhaust, for free. Instead of dropping a few $100 on an aftermarket can.
 
I did it and didn't have to run a programmer or anything. It's just to get a decent sound for free. I used the turndown tip from my HMF on mine and it looks "ok". I didn't notice any power difference. To truly feel a power difference from your exhaust you need to get a full system that comes with larger sized header pipes and have it tuned/jetted by someone who knows what they are doing. I have to admit, the stock exhaust mod does sound pretty decent.
 
did this today sounds sick .....i love it ........

Yea this is common as the ehaust now flows better and it needs more fuel to accomodate.
