I just got done installing the bbk longtube headers, and i got it all done and back on the floor. Well we cranked it over and doing very good, idles very well and low rpms it idles nicely. Well when you give it some throttle you hear a very small exhaust leak. When you shut the hood you can't hear it. Do you guys honestly think this is a major concern or something minor and shouldn't worry about. In due time if not a serious thing i'll take it to somebody and get it tightend up. Plus how much do you think it will cost for somebody to retighten the bolts on the passanger side header.

 

Well since you say it's a small exhaust leak and you say it's under the hood I'm guessing it's where the header connects the the motor. I wouldn't worry about it. As the header gets broke in the metal will expand. However, after a couple weeks if it hasn't sealed up, when you go to retighten the bolts make sure the gaskets are seated correctly. More than likely you have them right because that's not too hard. I really think the metal will expand and stop the leak.

 

The leak won't go away, that's only a sore knuckles hopes and dreams. It's not the end of the world performance wise and nothing horrible can happen from it, but it's still a good idea to find the leak and fix it.
