Exhaust Diameter, Visual Comparison

[A20A1]

This is an exhaust diameter comparison:
RIGHT: 1.75" that came from the flex pipe to the cat.
LEFT: 2.50" I welded this piece in place of the cat.

wow, looks loud. i would do that if, but in NJ... just no. you lucky fella. i bet you can really feel the difference.

yeah how much does that help? i am thinking about trying the same thing...

maybe if i put a muffler on my car it would help!! hehe

bigger isn't always better... if you don't plan on heavily modding the a20 then go for 2.25"... it's a minor step down, but you'll still gain enough flow over stock to nottice the difference.

I took pictuter of the entire welding process, unfortunately I didn't take a picture of me using the pipe cutter.
as soon as my friend transfers the pics from his digicam to a CD I can start posting them on my web site. :D

It won't be loud... my muffler always quites the exhuast down... even when I'm ripping it at 7,500 rpm my friends still tell me it's not loud... only if I fold down the rear seat and let it resonate on the inside of the car... then it gets louder then it does on the outside. :confused:

what does your car need to get moving again?

I think the crank bearings are worn out and i need a new trans... other than that i got all new oil coolant and spark plugs waiting to go... oh and that monster coil.... just a sec while I revive an old post.
