Best tuned pipe for stock hpi F4.6 mill

[Splocal]

Hi guys just wondering what would be a good pipe for my F4.6 mill. Looking to gain a little power if I can. I keep seeing the ofna 086 as a popular choice. Would this be a good fit for my mill? Will I need to retune my engine after putting a new pipe in?

pipes imo are personal preference. The only pipe i have ever noticed a difference was a buku. I love a swear by them but pricey. www.bukupower.com as for retune with say an 086, you might have to touch the hsn a biit

if you have a stock x with 8 shocks on it still and you want a 086 pipe you have to go with the ofna 086 pipe. the dynamite 086 has a rounded header and wont fit with 8 shocks on the truck. so ya my vote is for the 086 pipe too

I've got the big bore shocks Only 4. But I have considered adding the extra 4 shocks and lowering the truck to be more stable. I have a black polycarbonate exhaust I was looking at the polished hpi pipe or ofna 086. I'm gonna check out that buka though.

Wow that buku looks sick! Sold out right now though. They didn't show a price.

As already posted pipes are personal preference but the 086 and cvec make the most power in my application on my 4.6. Your mileage may vary

Ofna 053 good mid range power
063 good bottom end power
086 good top end power

you can deburr and open up the stock HPI manifold with a dremel tool and see some gain also
