Pete,

As usual you were, of course, right about the air bridge. I built a sleeve yesterday from some aluminum sheet stock I had laying around. Pretty much along the lines that Paul has outlined in another post. Took the car out to thrash it a bit. When I got back, I popped the hood, and lo and behold the air bridge was where I had tightened it. Previously, one corner of it would have been sliding off the air cleaner housing leaving a gap. I could always tell because the idle would get erratic. I think tho I will use the one GC has pointed out on ebay. Its smooth, doesn't have ragged metal edges and for the money, looks like a nice piece coming from up the street in Milwaukee.

I predict.... Improvement !!!!!

So here's the dilemma. Do I get an Xpipe like the 3" SS Magnaflow for about $60 and install w 3" pipes in place MF resonator OR get the SW xpipe for $350
+ 3" pipe and install? Do I go for just eliminating the restriction and dyno to test the hypothesis OR put in the SW xpipe which would stay there?

well you know the SW X pipe works.. if installed there is no change you will not be questioning that pipe then

Do you really think that if I remove resonator and sub a decent Xpipe I won't see a change? I can get xpipe, straight pipes and install done for price of just the SW x. However, if I am going to end up with SW, what about cost of removing the brand x xpipe and installing SW later?

No, I think you WILL see a change, BUT if you use a different X pipe and the numbers don't move as much as you think/ Pete thinks, then the exhaust still is a question.

XfireZ51 · 10-16-2011

I think the reason I should do the SW x is economic not for the horsepower. Frankly I could skip the x and just go straight
to the mufflers. According to what Paul described as the shortcomings of the MF system, a standalone X would be an improvement. Not sure that SW X is worth that much more. At least I haven't seen any indication of how much more it's worth.
