How do I check my cross over pipe.  I am so new with this turbo engine I don't know what to look for.  I can hear an exhuast leak up front and can smell one at an idle.  Could this just be a bad manifold or is it the cross over.  

Which then leads me to my next question.  I've heard that the Jeff M crossover is like $500.  Is it that much better.  Couldn't I just have my old one welded by a exhaust shop.  If it produces a considerable horspower gain I would do it.  Also if it is leaking, by seat of the pants where would I see the difference.  When I punch it on the highway I can feel it pull but then it is almost like it quits,  but boost it still reading good.  Is it cause the boost is leaking out through the crossover?  BTW I've had it to the track already and it was disapointing, 16.19@84.99.  not a good trap speed which would go along with what I am feeling.  I felt no pull in 3rd gear at the track.

Is there a website of a listing of all the Jeff M products.  Or do I have to email him to get a listing of all he offers.  So far I am interested in the crossover, top gun160, and the adj. shift improver or whatever it was called.  But everytime I open up a new window there is another product by Jeff being talked about.  So is there anywhere I can get a listing of everything?  Or just email him and he sends me a email catalog back?
