i found out yesterday i have an exhaust leak. can the leak cause a loss in power?

sorry to hear about the leak in your exhaust. as for it causing you to loose power im not sure but someone will be able to help you out with your question

Not sure the effect of an exhaust leak on power probably all depends on where the leak is.

Well, whenever I got my high-flow cat installed the first time, I had an exhaust leak and I don't recall any loss of power but I know that I used a lot of gas for some odd reason.

the leak is before the muffler. i still i have my exhaust tone but it just doesn't sound as crisp. i have also notice a loss in gas mileage as well. [???] i'm gonna try and get it welded this weekend.

loss in gas mileage??? hmmmmmm itneresting

Better go but a tornado[B)] to get better mileage

an exhaust leak won't affect your power or milage unless it is such a big leak that it is not connected a small leak the engine will never know... just irritating to the ears

leaks can cause problems, check around the bolted flanges before you worry about welding

Make sure all your gaskets are intact and installed properly, if not replace them with high quality ones. My HKS cat-back came with all new gaskets

YO! Hello all leaks can cause problems in the exhaust area..If it is to cloose(spell check) to the engine the motor cannot scavange enough of good back pressure.So gas mileage will decrease. Back pressure is a good thing for performance--In small doses.Here is another good reason to ask why do we not have keyed cams on the timing gears..Just fix the leak get new gaskets and what ever it takes..!Its easy to fix with a little elbow grease.
