how much power does a base 2.7 really get from these exhaust mods?

in my experience, having modified several cars - exhaust mods tend to not make a huge difference, but if they do, it's usually in responsiveness or way way top end power.

do the cat delete pipes, headers, or muffler setups do much to make a car *noticeably* faster or is it all about sound.

i'm on the verge of buying my dad's 2000 2.7L - and bone stock it sounds amazing. i wouldn't pay money to change teh sound. i maye could see doing it down the road if i was going to pick up 10-20hp...but somehow i don't see that happening.

am i wrong - does a full ehxuast make *real* power you could feel?

I can't say if my system adds power (probably negligible), but throttle response is far quicker, with no lag on downshift blips. I must also add that I have an Evo Hi-Flow intake on the other end.

In my mind it's worth the sound alone...sounds like a mini GT3RS.

Better exhaust note by changing exhaust - yes.

Looking for hp gain? Plauhease.

Friendly reminder:
Your car is god-damn pre-tuned by german engineers.

Increased power? Maybe, at the top of the rev range. Better throttle response? Absolutely. Better sound? Thats a judgment call only the individual can make.

I am running TurboWerx headers with the "new" FabSpeed exhaust (yes, I'm catless), combined with the RoW software program, and a lightweight flywheel. Throttle response is amazing. I am probably making a smidgen more at high RPM. I love the way it sounds, and my setup does not have any resonance issues.

I am working on welding in some high flow cats into the midpipes in an effort to be more socially responsible.

Hope that helps

Patrick
