Im getting a custom job done to my 2002 max, im getting a custom B pipe made 2.5 inches in dia, from the crush bend pipe back to the stock muffler, and custom welded on. The resonator will be left on, im doing this until i can get my Y-Pipe in.

The shop is charging $90

Will i experience any gains? or any HARMFUL results?

thanks

 

-I had that done when I had the exhaust shop installed my SFC's. The shop guy pointed out the restriction and recommended that I should do the work. I was convinced when saw the crush bend pipe, located right after the B-pipe resonator. I got it done for only $40. It is much cheaper than buying an aftermarket B-pipe. I did notice a better throttle response afterward. No addition noise or any problem so far.

-You should do it but ask him to lower the price, say $60?
Good luck!

 

damn $40!!!!!! Im goin to low ball the price now!! thanks !

 

I heard that the most restrictive piece is the b-pipe, not the y-pipe. Someone said in another thread that only having the b-pipe should yeild the same gain as having both a y-pipe and b-pipe.

does this make sense?

 

Really? Has anyone dyno'd without a y pipe and just the b section changed?? With resonator on or off? Anyone have any insight on this? thanks

 

Larry was the first to install the Warpspeed.

I don't think he dyno'd with just the b-pipe but he did mentioned in one of his post that he did not feel (butt dyno) any difference with just the y-pipe, but the did when he also added the b-pipe.
