BBK 4008 High Quality Chrome 1 5/8inch Header System For A 2003 Nissan Tsubame

i was skeptical when i read what the other people wrote but once i had them on i really notice a difference in sound and it picks a little faster when i step on my mustang. it was hard taking off the stock ones but it was really simple putting them on. All the parts were there not like the other reviews mentioned.

I notice just a little power not much. The product look good under the hood was not hard to install just took time.

Stay away from these headers. I own an 02 Mustang and first off i had to jump through hoops to get some caps sent to me from BBK to cap off some pipes that were on the primary tube on both headers. I have no clue what those are for but they dont apply to my car. Secondly after i recieved the caps i went to put on my headers and i found out that the bolts that they sent me to bolt the headers to the heads, DO NOT WORK! They are too large and they dont even fit through the holes in the headers! An thirdly, the exhaust flange bolts from my exhaust manifolds dont screw into the threads on the BBK headers because those threads are to small! Stay away from these Headers unless you want to spend countless hours searching for the right bolts and spending extra money to put the stinking things on.

The headers fit well on the engine but were missing the 4 most important studs to hook them with the tubes that connect the catalytic.. so i had to do some serious adaptations to connect that.. took me over 5 hours to do this and about another hour looking for some studs to improvise for the 4 missing studs that connect the headers to the tubes that go to the catalytic, please make sure next time that nothing is missing cause it really made the labor even harder then it already was.
