Took my car to get an o2 housing installed couple days later i notice a rattle coming from underneath my car. Taking a look at my downpipe i can see a pretty big gap between the o2 housing and my dwnpipe. I take my car back to my mechanic (who did alot of good work on my 2nd gen gsx) and he puts spacers on a cross member and tells me with a 3" downpipe i need those spacers. Is that right? Its a megan O2 housing with an espelir dp.

 

sounds about right. does it rattle anymore?

 

No but ithink i got an exhaust leak there but it could just be me trippin
