What do you need to add a pipe to a 700R? Such as filters, programmer, powerlid, etc. etc.
What exhaust system seems to help the 700R the best through the powerband???
Any info will help.

 

I put an HMF Slip-On on mine and it helped out all the way through the powerband. I also installed a trinity efi controller at the same time. You really need some type of efi controller when you put on a pipe or she will run lean. I think that the biggest hp numbers I heard of were with looney toon duals but I don't know for sure.
