My Down Pipe on My H22A 4-2-1 header has a leak before the o2. So my o2 is riching the mixture. I going to get it welded but was wondering if Any one knew any one that might have any JDM OEM down pipes laying around? The thing I don't want a aftermarket due to the lack of Reliability. If you have any ideas pass them along. This car is a daily driver.

 

im runnig complete 421 mugen header+ RSR catback + HKS muffler.no issue..what's is bothering you?
