Hey, i have the hks axle-back and i am now looking for a full cat-back system since i know have the headers in my car. Now my question is should i get a cat-back system that is made specifically for my car or use the hks axle-back and custom build the pipes to the headers so i can make sure everything is the right size to reduce back-pressure. I wanted to sell my axle-back for 280 but now im debating

 

You should keep your cat and go axle back. In the long run it will save you a ton of problems

 

You don't want to reduce back-pressure by much because you will lose low-end torque that way.

Just ditch the HKS and go Descendant/Tsudo... My Tsudo bolted on perfectly and from what I hear, the Descendant is the same way.

 

Its true I have the Descendant straight bolt on no fuss no hassle all gaskets and hardware included.

 

yea i guess imma sell it really quick just to get it out of the way, and then ill go with a cat back...im thinking descendant or greddy..i have the money right now to get either but i wanna sell the hks first

 

do u think i will gain anything from doing the switch..or should i wait and just spend the money on suspension and rims now...i have about 600 i can play around with it...no turbos i want strictly n/a

 

If you are looking strictly N/A, I'd stay away from the Greddy. It's got a larger pipe diameter, which would be great for turbo applications...not so much for N/A. Also, it's mad expensive.

Honestly, It's hard to tell regarding gains. Since you would be running a complete exhaust from header back, you will probably see better gains than me with just the cat-back. The only way you'll REALLY get good gains from any bolt-ons would be to get the AEM FIC and dyno tune that bad boy.

It's your call, but for the $600, you'll definitely notice more noticeable results if you grab some springs and a strut bar.

 

well i have friend selling an aem fic for 160 bucks so im thinking about getting that really quick, and i was thinking that since i have an axle and headers and intake, i might as well start with the springs and strut bar and also motor mount...thanx for the advice

 

160? I'm jealous! I really want to get one, but not sure about how to go about the install...or where to find a shop that will dyno tune for a reasonable price.

 

yea i know how u feel..i want to dyno my car but everyshop i call tells me they only do motorcycles..but imma just buy just in case i want to put it on in the future! imma hold off the cat-back

 

I like that logic, man. I'm definitely done with 'power' mods (after I get the NST crank pully, that is).

Time to get lower and stiffer ;)

 

Is your HKS exhaust still up for sale? if so whats a reasonable price youd be willing to sell at? thnx

 

i was gonna sell it at 300 thats including shipping

 

i've only had it for about two months

 

Just something to keep in mind. The most highly recommended tuner shop in my area (small area, so take it for what it's worth) suggested not doing a tune if all I had was bolt on mods because it wasn't worth the money. Basically said it'd run about $1K with the FIC and tune and I'd only get another 10-15 hp. Just something to keep in mind.

If you can get the $800 AEM FIC for $160 however...

 

i already got the aem fic controller..so basically a tune is about 300-400 dollars?
