Free flow exhaust.
I want to give my Patrol a little bit of a grunt on the exhaust side(opera voice). Want to fit a free flow, but the noise(4.8 music) must not be irratable in the cab. Where shoud I go in the Cape Town area. Has anybody done this.
Time and tide waits for no man.

Re: Free flow exhaust.
I had a freeflow fitted to my GQ by Maus in Pretoria R3110 incl for a full stainless steel 63mm unit. Up to 3000rpm it is whisper quiet above that it becomes angry though and let you know its not a puny 4cylinder up ahead. I was afraid of a drone at speed but no intrusive noise at 120km/h. I am very happy with the result.
I would recommend you phone Maus and get some advise as they specialise in Nissans. 012 542 4990.
I always had good service from Powerflow in Parow.
Good luck, that 4.8 will have a serious growl with a freeflow.

Re: Free flow exhaust.
G-Man het 'n 63mm SS freeflow op sy 4.8 en dit klink baie beter as die standaard stelsel.
Die klank is egter nie hard genoeg om te irreteer nie.
Ek wil dieselfde doen op my Patrol.

Re: Free flow exhaust.
Tjaart, which exhaust manifold and exhaust system did you fit and what did it cost?
I suspect I have a cracked exhaust manifold (there is a small chance that it could be a gasket only, I suppose), so I might also go for a branch manifold and freeflow system. One concern that I have is that branches often increase the underbonnet temperatures so much (probably because of the lack of heat shielding and the fact that the thin steel tubes have less thermal resistance than the cast manifold) that the electrics/electronics start feeling some distress. Have you noticed any problems in this regard?
Have you noticed any loss of torque at low rpm since fitting the branches?

Re: Free flow exhaust.
Hi Vaatjie. Ek het n 63mm powerflow op my lorrie gesit en it kicks ass!
Mooi klank, stil vir die langpad en as hy daar by die limiter gaan draai kry ek sommer hoendervleis...

Voor jy oorgaan tot die daad, hou net die volgende in gedagte:
1. Gaan jy die katalisator uithaal ? Jy kan groter gaan op die pyp se diamter, maar as jy die cat inlos dan defeat jy soort van die hele doelwit! Onthou net daar is 'n lambda sensor voor en na die cat. Jy mag dalk dalk kalibrasie en ECU lesings prpobleme optel. G-man hoe het jy rondom die ene gekom?
2. Indien jy 'n chip wil insit na die tyd, gaan gesels met Frans (Tour de Frans) voor jy die exhaust vervang - met 'n free flow system is die cat nie meer daar nie. Daar is lesings wat geneem moet word vir later se programmering met die chip.
3. Vra vir Frans oor die downpipe se ontwerp as jy ekstra krag wil he sonder om bottom end torque in te boet.
4. Gaan vir die sporty sound weergawe - ek was skrikkerig totdat ek Sondag Gerhard s'n gehoor het in die Du Toitskloof tonnel toe hy daai gearlever teruggetrek het en die petrolpedaal 'n bietjie weggetrap het - pragtig! En op die roete was die engine lekker stil - glad nie steurend nie.
Ek reken na ek met Frans gesels het is 'n free flow exhaust en 'n chip op my lys en soos Jacques gese het - Rodney Newsham - Powerflow Parow is jou man.
OT: Kerels ons het Sondag lekker gespeel en gekuier en inligting uitgeruil. Maak weer so!

Re: Free flow exhaust.
My 4.8 het nie 'n katalisator in nie
, hulle het seker eers later daarmee uitgekom.
Ja G-Man se Patrol het vir my hoendervleis gegee in die tonnel

Re: Free flow exhaust.
My Patrol het ook nie n cat in gehad nie!
Maar daar is sensors en dinge bo by die manifold, lyk selfde soos die op die cats. Ek hou meer van honde!!
