Hi everyone, I've been gathering as much information as can since I bought my GSR a few weeks ago.

For the record, I'm not looking for huge HP gains as the GSR is my daily driver. (Just want good gas milage)

That being said, I have already purchased a yonaka cat-back and a cheap eBay SRI that will be fitted with a K&N filter.

Here is my question...are aftermarket header really worth the money when paired with an SRI and cat-back exhaust?

Or are the stock GSR headers good enough for my setup?

I just want my engines air flow to be as efficient as possible.

 

99 Acura Integra GSR B18C1

The GSR is also lowered on coil overs, so ground clearance is a bit of a concern if new headers are in order.

I have been looking around and am slightly confused on the design differnaces as well.

4-1, 4-2-1, Hytech rep, Toda rep, TRI-Y, OEM ITR, Ram horn....just not sure which one will fit the GSR without modification and offer the best ground clearance.

thank you
