I got my greddy ti-c for my gsr yesterday and I get the whole thing bolted up and the cat that was on my car is too long, idk if its stock or not but it looks stock, my cat is 17.5 in and the gap from the downpipe to the strait pipe is only 13.5 in. Is there another cat I can buy? or will I need to have a custom cat fabed....

 

or should I take it to a shop and have them shorten the strait pipe?

 

problem solved, the strait pipe to my local exhaust shop and they cut 2 in out of it and then flared 2 in so i could adjust the length myself, did it for free too

 

glad we could help lol

 

haha yea i brain surged and riged it up myself, aint the prettiest but got the job done, and i figured out why it was 4 in too long, was because they mislabled the box and sent me a 4dr gsr cat back instead of 2 dr
