I have a 2000 Accord EX with the 3.0L V6. I couldnt afford the full Cat Back Exhaust and headers as of right now so I am going to replace the factory mufflers with some Magnaflows for right now. My question is: After the cat there is a siliencer, a pre-muffler, and two stock mufflers. Will it help or hurt the engine to put straight pipe where the siliencer and pre muffler is?

 

just get an axle back setup unless that mid section is rotted out. comptech and i think magnaflow only make axle backs and not catbacks for a reason. the silencer is there to keep the sound down, i good one doesn't effect hp a noticeable amount.

 

save your money, buy thge comptech header, and run a single catback piping system, stainless steel and 2.5"......you be much hapier
