Tonite I was out racing around on some curvy back roads and After I got done I noticed a clicking or flapping noise when I acclerated, but only while i was in gear. It sounded like the exhaust somewhere but I couldn't figure it out. I just installed an OBX 4-2-1 Header and a OBX High Flo Cat. Everything was fine until tonite. Could someone please Help It would be greatly appreciated. Thanks

By the way I have a 93 Vtec Milano Red with a ACT Stage 1 Full face clutch and Extreme Pressure Plate, an XACT Prolite Flywheel, OBX Header and High-Flo CAt and a CP CAI with k&N cone filter.

had this problem when i swapped my engine.... bolts from the header to the downpipe become lose from extreme hot/cold... try tightening them up again, i bet they're lose, and also tighthen them when they are hot, but be careful

if that doesn't do it, check the ones from the manifold to the head. Did you replace your exhaust manifold gasket?

I'm getting a noise as well, its sort of like a raspy wrr when you tap on the gas a bit .. also, I notice when im in neutral I can smell exhaust fumes in the cabin if the fans blowing .. I popped the hood and accelerated the throttle cable and definately as expected, downpipe to header is loose.

I didnt put a gasket in there either ( my bad ) ... so I'm going to do that soon as my new o2 sensor comes in..

Thanks for your guys inputs i'm at school right now but i'll let you know if that fixed the prob. and yes i did replace the head to manifold gasket.

Ok I tightened up all the bolts on the header and in the process i found one of the header ot downpipe bolts was stripped. I replaced the bolt and now it sounds almost but i think im just going to save up for a greddy header.

Any compliments or complaints about that header?
