custom piping and header 05 civic lx

[CachFr001]

Hey guys I have two questions :
1. If I put headers on my civic will it sound rice? What will I get performance wise?
2. If I put custom mandrel bend 2.25 inch piping will I get performance results? What will it sound like after?

I already have 4" rs type exhaust w/ 2.25"inlet. resonator delete. This just made my car sound really deep and nice opposed to what everyone though a resonator delete would sound like.

Please help

It's a 4 cylinder so there is only 1 header. There will be next to no performance with either the header or the piping. This isn't an old muscle car, bigger exhaust isn't better here. Your only bang for the buck is to go forced induction or put in a bigger motor. D series motors don't respond well to bolt ons. These were built for economy and it is tough to squeeze power out of them without lots of money or boost.

Also both aren't going to change the sound much more than you already have.
