Straight through on N/A 
in my opinion. Destroys the low down torque when I got rid of mine and put a jetex on there it felt like it had a lot more low down power. Which is more important for a road car.

Have you done the old rev to 5-6k and blip the throttle trick to see if it will get it moving? |

I had decat plus standard exhaust.and induction was good low down on rev range.I now have a decat powerflow car back but need to get smaller silencer in the middle section to get it poping. Two of my mates who have gti 6 s one with decat+straight thru+backbox.second has decat+tiny middlebox section+ backbox.booth pop an bang very differently,2 is constantly poping,flames on throttle let of,1 literally bangs like a drum once loudly then fades with smaller pops and bangs ________________________________________ Rallye build: 11 November 1998 - a WednesdayTeam rallye,built for track ----Click this if you like rallyes Rallye dead  Secret Team Astor... |

I must admit, when going through mountain terrain or tunnels etc, the noise bouncing back at you when the driver's window is down is fantastic. ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

On standard mapping I expect the fuel amount is very little when coasting in gear without throttle hence no/little unburnt fuel getting to the exhaust. Carbs on the other hand will still be supplying fuel as the engine is sucking it in under vacuum.________________________________________ |

i had my decat for all of 3 days. Was from tip top exhausts near spaghettit junction (full custom ss from scratch in 30mins for 200 notes). I only got pops after very high rev gear changes. Anything else more than this is a sign of overfueling/unburnt fuel in exhaust. Which can burn valves etc etc.________________________________________ the world is changed by people in sheds |

I believe thats one of reasons mine is so prolific. I bought my decat new at the start of 2005 so its had plenty of use and time to get coked up.  ________________________________________ "Supercharged - 454.1bhp/317.5lb/ft"Peugeot 306 GTi-6 2000 (X), Moonstone |

I'm not sure if anyone read this. My car never popped or banged with the magnex de cat and full 3" system. Now I have a custom zorst married to a magnex de cat i can't stop it. Flames and bangs. also think devil decats produce more bangs. My argument, zorst really makes the diff. ________________________________________ Previous china gti6 and Rallye owner.Now a proud Astor Gti 6 owner. Missing he BMW already... |
