quick greddy sp-1, sp-2 question Options

[celicaboy95]

Hey guys i just have a quick question. i bought a 1995 toyota celica with what im pretty sure is a cat back sp-1 possibly sp-2 exhaust already installed. as of recently i have a hole in the piping that connects the the cat. After calling greddy they told me that i cannot order just the pipe i need. So what i have to do is have it custom built/welded but im not sure what size diameter the current pipe is. I think it is 3" but would like to be positive. any info would be great.

thanks

GReddy was the only company to make a complete catback exhaust for our 1994-1999 Celica GT's/ST's - both the GReddy SP1 and SP2 have 2.5" piping. The only difference between the two is the muffler design.

isnt the greddy stainless steel?

yes sir, it is, SUS304 Stainless Steel piping including the muffler.

i always thought the piping was 2.25"

the SP1 has a painted cat-back pipe, as well as muffler chamber, and goes up about 1/2" onto the muffler tip. as for the SP2, i'm not positive.

i believe the greddy sp for the celica has a 60mm pipe, which is 2.3622" (approx 2 3/8"). so, depending on the side of the pipe's wall thickness, you can either slide a piece of 2 1/2" piping over it, or a piece of 2 1/4" piping into it.

hope that helps.
