2008 altima to beat genesis coupe turbo

[cc247]

so my main goal is to make my car waaayyyy faster than those genesis coupes and the scion frs, subaru brz so what ive wanted to do was get these mods to make it faster which from what ive been told it would give my car around 65-100 more hp which should just kill those cars but these are the mods and i was wondering if any of you altima coupe owners have used any of these parts and how much you payed for them and if they do any long term damages, anyways these are the mods.

-STILLEN CAT-BACK EXHAUST SYSTEM
-Bully Dog Triple Dog GT Tuner
-K&N 69 Series Typhoon Intake Systems
- Stillen Header

these are just from what ive been looking around on google anything to add or i should drop from this list and im trying to do as much as i can to this engine without having to engine swap ill engine swap eventually for a twin turbo of some sort i just love the altima body style so im gunna keep this car but anyways i want to make this car as fast and possible without having to engine swap and please dont mention why make this engine faster if your going to swap it eventually and i want to because i just want to haha...because an engine swap would cost a lot of money and idk if im gunna do that but anyways if anyone has these parts or have used parts to make them faster please tell me thanks!

Stillen Header, and Straight pipe 3" is what I have, and it sounds very nice. It surprisingly is not too loud either. I also recommend getting the Speed Force Racing turbo kit as well.

You're not going to get anything near 65-100 hp from those mods.

I have a lot of upgrades on mine, it has 415 wheel hp and 415 lb torque @ 9PSI on the turbo
