Which ones had figment problems?

 

ok well this is the problem. on that link i posted, the one that falls under the ls catagory which is mine, is 13 inches long. the cat on my car is like 17.5 inches long. which is the same length as a gsr cat, but the bolt pattern is different...i think. so i just want to know which one of those would fit my car...

 

can someone please do me a huge favor and just look through the links i put up here and find the one that will fit my car. every website seems to have a different set of specs and i cant understand why. this is another link of ones that could fit.

this is the cat i have, i hope these pics help. i just want to find one that fits. thats all....

 

If your car is 100% stock then the LS one should fit.

 

that one on amazon is for a 94-95, which means obd1 your ls is a 99 obd2 which needs the secondary o2 sensor, the 94-95 doesnt have a bung for the o2 sensor.

do not get it

ok well which one should i get?

well i have an aftermarket 2.5 inch catback and a 2.5 inch aftermarket header. so its not stock. but i still need the same bolt pattern, even if they are farther apart.

if you go to kteller.com you can have them make you a custom high flow cat. Yoiu tell them what the length is, and what kind of flanges you need.
