PacBrake to 4 inch

[kompressor]

I am getting ready to install a PacBrake and want to change to a 4" exhaust. I have an early 04 and plan on getting a brake for a 04. 5. Where can I obtain a 4" down pipe with out having to purchase a whole exhaust system. I plan on going 4" from the turbo to the existing muffler for the time being. Thanks for your ideas.

We can offer pricing on the pacbrake if we haven't done so yet... send me an email...

Those customers who have done this have gone to an exhaust shop for an adapter, cut and welded into their existing exhaust until they were ready to up grade their exhaust...

Remember that the stock Pacbrake elbow does flow 20% or so more than the stock elbow... you only need to consider upgrading if you wish to greatly raise the HP...

MPRB, has the down pipe. 4'', then purchase 4'' to 3. 5'' reducer about $35. 00 and clamps, cut the first extension pipe for the reducer " DO NOT CUT THE T. O. P this way when you upgrade to 4" it will bolt right up to your 4" T. O. P.

I installed the entire 2005 exhaust (less cat as I used the MRBP elim pipe) on my 2004 after I bought the 2005 PacBrake. The factory down pipe 52121600aa list is $89. 75, cost $67. 31. If you want the other part numbers PM me.
