Séb_-Nx 03-10-2002, 06:35 PM I'm getting a bb det and I want to get a 2.5'' ehaust line mandrel bent.So my question is: Is it better to get a 3'' or a 2.5'' if I plan of getting about 230-240hp??I have heard on this board that 3'' is better,but why? TIA guys!! Wicked R 03-10-2002, 06:53 PM To put it plain and simple... Turbos hate back pressure... the more free flowing exhaust you have, the more happier your turbo will be... Go with the 3 inch... I guarantee you wont regret it Séb_-Nx 03-10-2002, 07:34 PM yeah,but I think it can flow very well with a 2.5'' as well.I'm not getting 300hp there... domiguy 03-10-2002, 09:07 PM you're not going to be getting 300hp... for now :-D ... you will probably get power hungry and want more, so if you just do 3" now, it won't be an extra expense later... and I believe even though you aren't going to be making too much power, 3" would still be much better than 2.5" (I could be wrong but these are my thoughts) | ||
