More engine noise after headers??
I just got done with installing a set of Dynatech headers and have noticed a distinct increase in engine (noisy valve train type) noise. I expected an increase in the exhaust volume, but not an increase in engine noise. I just got the car back on the ground yesterday and don't have enough miles to retorque everything. Is this normal or do I have a leak someplace?

The added noise is normal and it also occured with me after I had new headers/cats/x / installed. Since the power output wasnt really noticable...i dont think id ever go the header route again . Id rather have a quieter operating motor.

Well I made a pass on all the bolts and found 3 that I could put a 1/4 turn on and a few others that moved a bit. Also I think I have a leak where the X meets the over axle pipes. I'm going to take it to a muffler shop tomorrow so they can put it on the rack with it running and see if they can find something

This comment is really surprising.....when I had AR headers & high flow cats installed on my '05 there was a distinct "seat of the pants" power increase. Included with the install was a dynamic tune (ECS in NJ), which I think is important with all engine mods. Did you have a tune done?

YES, you might have a leak!

It's TOTALLY NORMAL.

I took it to a muffler shop and it turned out I did have 2 leaks. Either the clamps didn't hold or while I was adjusting everything else the X to over axle joint slipped. I had a tiny leak from one and a pretty good leak from the other. The shop pulled it apart, added some sealer and tacked it when they put it back together. Major difference. I've still got more noise than stock, but its much, much better. Now all I need is the CoW touch .....
