This exhaust has been modified so it will fit my jdm itr header..therefore it was extended about 10? inches. You could have a muffler shop shorten it again for about 20 bucks or mate it with a carsound cat. I made 178 whp on b18c type R motor w/ jdm itr 4 to 1 header, jdm itr cat, and this exhaust. I will sell it for 300 plus shipping. I've had it on my car for about 2 years. PM me if you are interested..it will be off the car in about 2-3 weeks.
