ok... i installed an option racing high flow cat and a spyder exhaust system on my civic. Da prob is dat da cat wasn't able to fit with da round gasket in it. Now i wanna knw, will i have da same prob w/ option racing headers when i get them next week?

 

Option Racing from Ebay? did you put the cat on the right way? it might just not be good fit because its not a higher end brand...But Option Racing Cats are just straight pipes and have no catalytic internals...But with your question i am saying they should fit since its the same brand but you never know.

 

well... i bought it off andysautosport.com both da cat and exhaust... n dey said to me dat both items were bolt ons... forget ebay tho... i dont trust it very much after googling reviews on car parts for my civic...

 

Andy's isn't too far off from ebay, just keep that in mind. Typically the cheaper exhaust setups will require some light modification to get them to fit correctly.

Hopefully, if you're doing the same brand of exhaust all the way back, they'll at least mate to each other..


Also, Please try and use full words, as it makes your questions much easier for us to read and understand.

EDIT: Moving this to the Exhaust section

 

well my spyder cat-back connected to da option racing catalytic converter with no problem. i'm planning to put option racing headers some time next week or so... i'm runnin 2.25in piping all da way for now... i just wanna knw if da headers will fit da cat
