I have changed all my old exhaust gaskets to brand new OEM ones because I was having a minor boost leak and now its even worse now. The car rattles like crap and I can't figure out why or where the exhaust leak is coming from. If anyone has a garage that can help me out Id appreciate it. It's raining tomorrow and I don't have a garage. This have been such a headache...

 

Spray the gaskets with soapy water...if it bubbles that's where the leak is coming from

 

Rattles when? Only when boosting? Check your vac lines too.

 

What do you mean by rattling? Like tapping a pipe rattling? I had and still have that problem. Check your downpipe or header area to see if there is close contact anything in that general area. If you hear rattling, it could also be that.

Keep us updated!

 

Yup, was going to ask that too. I had an exhaust rattle after going to 3". Kartboy poly hangars fixed that. So when you say "rattling" do you mean vibration or something is actually making noise?

 

Ever since I switched from helix catted to catless one, this thing feels like something is hitting the.cross member or something and you can feel it under your feet every time you let off the throttle. Its only holding 11psi when target is usually 18psi, so I'm guessing its before the turbo
