since i might just have a muffler and not full exhaust i might want to have one put on. what i have now im not sure of but i have a magnaflow muffler. since my car is already loud and kinda high pitched i was wondering what size piping i should get. i want it to sound more deep if thats possible. any info would help. my cars a 95 civic.

 

2.25 if your staying NA.

 

2.25

 

2.25" is ideal, you can even go 2"

 

unless youre planning on turboing your car id stay at 2...4 would be the way to go if you are planning on turboing

 

for N/A 2.25 is a good size

 

3 is for turbo.

 

4 is a bit excessive.
