I recently installed dc sport 4-1 headers on my 99 GSR but now im gettin a weird noise. I know that wen you install parts (intake, exhausts, intake manifold) the sound of your car will change...

BUT

my exhaust sounds exactly the same but now theres another noise coming from bottom where the headers and cat connect, so im havin 2 seperate noises coming from the car

Now i still have my stock cat convertor so could that be the problem?

 

Could be an exhaust leak, that happened to me when i put on a header.

 

so how would i fix that?

 

exaust leat meens that there is a gap a hole or some space in the connection of your pipes in the exaust.i suggest anyway if you just got a racing header put on to get a all new exaust. the pipes from the header and exaust probably dont meet up tight enough so your getting a leak.

 

actually thats probably it. b/c i looked under the car and theheaders seem to be a bit smaller outlet then the stock ones had but ya thanks alot!

is there anything else that could be the problem

 

Crank down the bolts with the springs on them. I bet thats where your leak is coming from.

 

thats great! should it be tourques to 35 lbs?

 

Did you put a gasket?

 

i had a noise problem when i put in my dc sport headers too, i put a donut gasket from honda in and voilA.!

 

ya it came with a brand new gasket

 

The donut gasket?
