anything else is good about these except making a whole sht lota noise?? does it even raise any hp without the full catback?

 

not really, 1 or 2hp i think...maybe not even. they also look good if u get the right one

 

Tips do nothing.

 

just get a full cat back exhaust system...like an apexi ws 2

 

Resonated tips won't do a damn thing except rust and sound like shit.

 

so i guess i should juss dump this free HKS muffler that i got?

 

You don't have to dump it bro if you don't want to. I'd recommend a full catback system like already stated. If your planning to stay naturally aspirated then I'd also recommend you upgrade the exhaust manifold and catalytic converter.

You can't expect much of anything from slapping on an HKS muffler on a stock exhaust system.

 

take that muffler to a muffler shop and have them custom bend you a cat-back and weld that muffler on.

 

sell it and use what u made for gas $

 

get the tips, i got some on ebay i got like 9 of them, i race like errday now shit.
