i have an 05 tc i want the most power for what i can buy and i was wondering if the zpi midpipe deletes the cat i know it deletes the resonator. if i have a k&n cai, mmw header and a zpi spipe and midpipe and hks exhaust how much power would i have to the wheels bc my dyno with just cai and hks axle back i had 142 hp at the wheels which is good considering the automatic looses 20 hp compared to the manual. now i have a mmw header ready to install but i have to buy an spipe and midpipe unless the midpipe doesnt delete the cat because i already have my resonater taken off.



k&n cai, no resonator, hks titanium axle back, 142whp

 

The mmw header includes the spipe. The zpi pipe will take straight through to your hks axcel back. You will have no cat or resonator. It will be one loud ****. You will probably be 25whp over stock with all your mods.

 

i call BS. 142hp with just cai and hks axleback? for one.. a stock automatic tc is like mid 120hp. a cai + hks axleback will gain about..2-3whp.

and you don't have to worry about a zpi s-pipe since the mmw header already comes with one.

 

the mmw header was used on ebay it didnt come with one that is why i asked

 

Post a pick some were 1 piece otherwise you will need some custom work.
