how do you messure exhust pipe size is it diameter or circumference

 

diameter.

Doesn't matter...the shop you go to should be knowledgeable enough for you not need anyone elses input.

 

damn joe. harshness. lol but yeah its diameter. stock is 2in from cat to resonator and then 1.75 from resonator back.

 

damn why does it go so small after the resonator that sucks

so i should replace the resonator with a 2inch in and a 2inch out and a 2inch all the way back with a 2inch in muffler so pretty much a cat back system hmmmmmm

might have to goto my local muffler shop and find out

 

If from the cat to the resonator was 2"...then there would be no more reason to buy anything more than an axle back since having 2" complete piping is MORE than enough for a 108hp car.

 

The pipe size is what helps the motor have great gas milage. It really is a wierd design, but none the less our cars are special like that.

 

so the best and safest bet is just go with an axle back set up

 

depends on what you want. A catback is a good way to go, but than again so is an axle back. :D

 

i want to keep my mpg the same or improve it while gaining a little better sound and proformance

 

 

ummm yer mileage shouldnt drop with 2.0 inch if it was 2.25 or 2.5 then it could hurt it but only cuz u would lose torque thus makin u rev higher equaling ____tier mileage. and the 1.75 to me seems to be more along the lines of cheaper , easier , and quieter. but then wadda i no

 

Than yes you might want to purchase an axle back if you really want to save mpg.

 

The piping from the cat to the resonator is 2"? I could've sworn it was 1.75"... hrmmm... Makes me want to take a piece of string and measure...

 

do it

 

I would assume its 1.75 after the resonater because the resonater creates back pressure, and less (volume) air is moving out of the resonator as it did when it was moving in the resonator.

 

everything before resonator is 2.0 everything aft is 1.75
