Will I Lose Power

[benkoau]

i recently got epa'd so im taking the 3 and a half inch exhaust off and putting the standard one back on but while i was at the workshop asking if i could borrow a standard item i saw a 2 and a half inch exhaust that looked a bit more restrictive but at the same time it looked alot more quite and i should be able to use that and not be bothered by the epa anymore but now my question im fairly sure ill lose power but how much

my car is fairly stock pod filter exhaust boost controller and i have an intercooler about to be installed i always thought the 3 and a half was too big for the amount of mods i had but i always thought less restriction more power ....i would like to hear your thoughts was the original exhaust too big for the amount of mods i have,will i be better off with the 2 and a half

thanks

dont take it off silencer + resonator should do the trick

If you are still running the stock turbo, then a 2 1/2in exhaust wont be really restrictive, as long as it is mandrell bent and has reasonable quality mufflers

i had the 3 and a half inch exhaust tested before i took it off 98- to 101 decibels obviously not legal so the guy i go to had a kakimoto exhaust 2 and a half inch it made a huge difference 86 decibels at 4800 rpms and i still have a 3 and a half inch front pipe i didnt think it'd be able to pass with the front pipe

With all the semi's and B doubles, plus the motorbikes getting around - 101dB is nothing. You'd think they would have their hands [and books] full enough, they must have very lttle to do in Vic.
