hello fellows, i got a question... i wanna change the exhaust system on my neon 98 soch, i got 11.1:1 compression ratio and 215lbs (on each cylinder) so if i put a 2 1/2 inchs exhaust it gonna be better?? i got a long header too!

 

pasesetter long tube headders have shown to have the most gains for a SOHC engine.

 

yeah i know that but my question its, if i change the exhaust pipe for another one bigger it gonna be better? u know that the sohc neon bring a 2 1/4 inches (two and a quarter inche) and i wanna put a pipe of 2 1/2 inches (two and half inches) so what u said about it?

 

yes the 2 1/2 is a good size for the exhaust i wouldnt go much bigger or you will loose power and it will back fire

 

thanks a lot bro, im aking cuz with 215 internals lbs i need som more pipe

 

yeah, sorry i had edited the post before but guess it did not stay.

but i added stock size is good as long as you change the SOHC mufler if you still have the stock muffler on there.

 

unless you turbo, you loose power going up any higher than 3, even at 3" you are risking loosing power, but 2 1/2 seems to be the magic size for the neon...all the performance exhaust kits are usually at 2 1/2.

 

2 1/4 is more then enough for the neon.....2 1/2 will be fine though...

even with a turbo on these cars, there is no need for a 3" exhaust

 

Stick with the stock size and invest the money somewhere else.

 

well i gonna get it not buy it! a friend work on a exhaust shop and he gonna give to me an 2.5" exhaust i got an HKS muffler and the entrace its 2.5" inchs... my uncle say that "whit bigger compression you have to change the exhaust system for a better perfomance" and he works with gt cars! so im cuz u know so much about neon and maybe the neon can be so kind of "exception" on the racing world!
