Ok, i have a problem. I have recently been told that the duals on my 98 Civic EX (1.6L) were killing what little *umph* my motor may actually have. For any information you mad need, of course it's one pipe (running off a stock header) back to under the right side of the trunk, and then Y's. They're simply two Magnaflow tips, and i was simply wondering:

ARE THEY TRUELY KILLING MY performance? (I was told something to do with 'back pressure') I mean, i'm running a 75 NX wet shot, and could i expect maybe a little MORE kick, with it ran back to one pipe?

 

no you dont need any "back pressure" they are saying that because its GAY AS HELL. what is the point. it doesnt help you out any and it looks ******* STUPID. Waste of money.

 

You have to have backpressure if you are running cats. Thats what a resonator is for. With out that, it would blow out the cat.
