that makes all my typing worth while.
i just visited jba's site and looked at their cat-back this morning and it says that thier cat-back tubing is 3'', just like banks
i emailed them to see if this is true, someone can call for a quicker responce. i then went to that ebay site selling the jba cat back and looked Very closely at the pic at the bottem. if thats for our trucks, which it may be, i wondered how the hell they run their pipe a few ft then to into the Y since theres a huge gas tank in the way. i also wondered why add even more sound dampeners to the 2 we already have. i then looked even closer and noticed that the 2 tubes with humps in them have O2 sensor bungs! it seems that the jba cat-back is a True cat-back exhaust by replacing all tubing and goes 1 step further then banks and replaces the 2 stock sound dampeners also. im just going on the pic posted on ebay here, i email jba about this also. that pic also give the impression that their tubing is only 2 1/2 up to the muffler then opens up to 3", that is if thats for our truck but if their setup is 3" like their site says, i suspect there to be little difference between it and the banks. well see what jba says....
