hi guys,
is the hks hi power cat back exhaust worth the money, how much power can i gain from this

 

There are better buys out there, HKS is not true 3" all the way.

Failing that its a nice piece but with hit or miss fitment issues. Sounds great, not too loud, built nicely. Cant speak of longevity though I would recommend 100% stainless exhausts only.

 

i have it, works and looks great.... installed perfect, fitment was perfect.... would recommend

 

Don't get it, POS. For all the reasons he said. The Main reason is it necks down to stock exhaust size, 2.1". Sad, just sad..

 

What abut the Carbon Ti? SS piping and I think its 2.5 all the way.

 

HKS is 3 inch til the muffler. Has a built in silencer that is like 2.5 inches. I believe a few people have removed it.

 

its a good exhaust, fits great, sounds nice. Hangs a tad low, but all depends if you drive over lots of speed bumps or steep gradients in the road (steep driveways, etc.)

Very popular unit

Yes it necks down (to meet the stock cat) to 2.5 inches. A 2.5 inch exhaust still can flow enough HP than most Evo's will make in their lifetime.

 

I thought it knecked down at the point where it connects to the cat?

 

Knecks down, yes its stainless, its heavy though and the funky overengineered rear mounting points are, well, a pain to install and align.

I also scraped the hell out of the can reversing out of driveways.

 

it does - to 2.5 inches at the flange to the cat

 

I've been around enough of them to know that they are quality exhausts...but like others have said they hang a little low. For the money there are equally good exhausts out there. I'm personally happy with my RSR GTII.

 

check out the JUN B.L system. they have a factory backed promotion on them right now!

 

i have the RNR. 600 bucks for a full 3" TBE. cant be that with a stick! pipes are pipes, you want a name you gotta pay.

 

i have the hks and im pretty happy with it. its NOT 3" but its fine for the power im making right now. ill eventually upgrade, just wish i did some research before i bought it because its not the best for the money. the best advice i can give you is research.

on a side note(and sorry for this being off topic) thats quite a list of cars you have for yourself BIG3_ETR. what do you do for a living?(if you dont mind me asking)
