I am getting my HKS Turbo kit next week and want to get a exhaust system to go with it. I was thinking I should do a 70mm or 2 1/2 inch pipe. Is there anyone making this exhaust? Or would I have to get custom made.
Also has anyone that has FI tested exhaust systems and sizes.

 

The HKS is only pushing what 140 hp to the crank and 120 ish to the wheels. I would suggest to get the skunk 2 60mm catback exhaust.

 

yeah i think for our cars the 60mm will be just fine.

for the most power just rock an electric cut out.

 

Ya the HKS site say 125.6 to the wheels, this is with a rear section only. there Hi-Power. With a cat back it should show alittle more.

Turbo car love free flowing exhaust, but with bigger piping comes louder exhaust, I just wanted to see if some one had already done the leg work.
There is a shop here in tampa that build custom exahust, I talked to him today. will cost just alittle more then buying a system. he is a well known honda tuner in Tampa, this is the link LHT Custom Exhausts - Tampa Racing

 

I wouldn't worry too much about the loud exhaust. turbochargers dampen the sound dramatically. it will be pretty mellow and deep.

 

Cat delete will bring the biggest gains for a turbocharged exhaust(and will also be louder, but yes tc's do dampen sound and bring about that sexy deep tone!), a good turbo manifold back exhaust @ 55-60mm will be plenty and you'll see some awesome gains. Full exhaust + good fuel/timing management + a good tune = more boost, more hp, more fun :-D

 

yeah im still debating on doing 2 1/2 straight back....no resonator or muffler.

or do the 2 1/2 straight back into my hks super drager and have an electric cut out before the cat

that way when i wanna be fast. i can just flip the switch and it will open up. then the rest of the time ill still be super quiet like stock

but for how much.

you might as well go to a muffler shop and have them just make you one.


im going for the stock look i think...


so that way you cant see my exhaust(cop attention getter)

just like a limp dick under my rear bumper.


either that or side exit

but that too will be stealth

 

once i start running more boost, i am going to have a custom 65mm straight back from the cat delete. and for my muffler, i am going to get a works muffler made for an evo.

this muffler.
WORKS

 

pssh ...buy my muffler if you want to be quiet heh.

thats what im thinking. keeping it quiet for stock driving and when i want to be loud and faster just hit the switch. thats what i think you should do.

 

but the dual exhaust sound super tempting. i think it would look nice on the fit.

 

Thanks for the Info guys.
I made up my mind and set a appointment for this tuesday morning to have the exhaust built. I am going to have a cat delete built and a cat back with a stealth muffler. 2 1/2 inch, about 64mm.
But I am going to make two axle backs, the stealth for daily driving (tampa finest don't like exhaust) and for fun I got the HKS 60mm Titanium muffler. This one i will use when I show the car

 

good choice with the hks ti muffler. i had the exact one.

 

I got the catback exhaust done on my car. I did not have the cat delete built yet. I wanted to feel how the car feels with just that. Wow what a big difference. It feels a lot faster.






2nd rear axle, this one will be my daily driver. You can only hear the exhaust

 

post pics when you get the turbo back exhaust built.

 

The 2.5 inch will be plenty....there is no specific exhaust for turbo supercharged cars either....u can probably get away with a 2 1/4 inch.
Good luck.
