 2.5" or 3" turbo back exhaust.Hi,
What do you guys think - I'm not sure wether to go for a 2.5" system or 3" system (2 decats and exhaust). Do you reckon that a 2.5" system will be big enough to flow upto 500bhp on a 2jz-GTE? My thoughts are that it will be, but top end might be sacraficed a bit at that kind of power? Paul. |

Re: 2.5" or 3" turbo back exhaust. i think 2.5 will be fine mate, nice and flowing. 3 maybe bit over kill.

Re: 2.5" or 3" turbo back exhaust. Not sure about your car paul but I know on 3000gt's the turbo cars have 3" and the na's have 2" as standard so would of thought 2.5 is a bit restrictive.

Chris they may have 3", but there are a few baffles in the way as standard, so wouldnt make much difference lol. 2.5" should flow enough in theory........hmmm.......should just go for 3" I suppose to future proof it.
