Small scale modification

Hello 2004 1.6 gasoline / LPG 2004 307sw I wonder if I can open the air filter and exhaust to my car. Lpg is a problem or if I can do whatever models you suggest I can add or remove the exhaust, it would be better if you have a nice nice sound control fln.

I wonder if I can get software on the stage 1 or 2 if everything happens ie exhaust + air fil. + How many horsepower the software increases

My brother Batuhan does not add software to the atmospheric vehicle because it is not useful because it is not a turbo, but it will have a 5 horsepower effect. If you want performance, you will ride on gasoline. The vehicle sw 307 has a weight of 1500 kg. With exhaust control helical control, you know the penalty if it is noticed in the controls. Instead of spending money on these things, get your car rim-polished. I think the dimming of the headlight will be more elegant.

Exhaust straight pipe and open air filter shifts between 20 and 25 HP. But +10 15 kuruş bay per kilometer according to usage. How logical would a catalyst cancellation be?
