Installed header. should i do front pipe? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I have the borla uel catless header installed. Is it worth it to get a hi flow catted front pipe or just leave it stock? Gonna get it tuned in a couple weeks and i guess i should make up my mind before i get it tuned. Will i get much more power if i replace the front pipe?

since you got header, I would get both overpipe and front pipe together to maxmize

i fugured that would be the answer. But what is restrictive about the over pipe?

"The factory part is made from 2.118″ OD tubing (like the rest of the exhaust) and has a couple of really sharp bends along with an area with a big crimp." 2.118 to 2.5 just more exhaust gas can go away better. I believe it is most restrictive is because it bends. Like a straight pipe breath easier but throw some curve and bends you gonna have a bad time (joke)

The overpipe honestly is not worth the money in my opinion. They make maybe 3whp with a tune if your lucky, not to mention fitment issues a lot of people have with them rubbing. I would absolutely go for a catted front pipe though, pretty decent gains with those.

so get the Nameless combo. $499 includes high flow cat and op.

One piece, Nameless Overpipe Front Pipe Catted with Helmholtz Resonator will flow very well and tame the rasp

WhiteFR-S · 10-04-2013, 04:10 PM

i was thinking about berk high flow cat $250

tonystewart · 10-04-2013, 04:14 PM

No rubbing, I installed to a FA20club EL header

Another vote for Nameless. On the stock header I doubt the overpipe is worth it, it'll add a little bit and subtly change the sound, but with a larger diameter pipe off the header abruptly dropping to the smaller overpipe I can't imagine the turbulence will do anything good for you. I had to do that for a bit, and I could hear the difference, sounds vaguely "not right"
