i need some feedback. I have an apexi n/a muffler on my car. it will soon be turbo. would i need to get the turbo muffler? i will probably get 3" piping.

Daniel

probably, seeing as how i don't think the N1 N/A uses a 3" inlet.

mrod006

the inlet is about 2.5 inches. i think that the muffler shop can flare it out, but my concern is the outlet. is the n/a outlet too small for turbo?

Daniel

unless the actually piping running THROUGH the canister increases to 3", flaring a 2.5" inlet will do nothing. you flare it out to fit 3" piping, and then what? it bottle necks back to 2.5" piping inside the muffler. i've seen the inside of both a N1 n/a and n1 turbo, and i don't recall either having the piping increase size inside the muffler.

mrod006

so i would have to sell the n/a and buy the turbo?

MiraiZ

you"ll be okay...its wat I have, but it makes the car REALLY quiet....

mrod006

that is what i like about the exhaust. the fact that it is quiet is good because i am going for the sleeper look. what size of piping do you have?

MiraiZ

The N1 piping is 2.36 ( I think...60mm) then my DP is 2.25->2.4"...so its..

Turbo--->2.25"dp---->2.4"pipe---->JDM cat---->N1 full exhaust 2.36"

When I say quiet...its not Cadillac quiet...the exhaust is very throaty and much quieter than it was when it was NA...

mrod006

would you think that it would be useless if i got my piping 3" because of the size of the inlet on the muffler?

have to agree....n1 sounds very nice with turbo..u could actually hear ur music in normal volume in fwy...but n/a...n1 is loud!!!!

if you are less than 2 liters in displacement and less than 250 hp, youll be fine with n1. I have it on mine, with a 2.5" testpipe. Everything fits, works, and spools perfectly fine and good. Its a great setup. I have it on my 96' ex (greddy turbo).

I have the complete apex N1 N/A piping and muffler on my GSR/Drag 3 and it's very quiet . I'm making 250hp, but it feels very restrictive, like I'm losing a lot of power. Any suggestions?

MiraiZ

get a dyno and see where the power starts to drop off...if its like towards the end of the curve...then it may be your exhaust is too restrictive...if it looks to still be climbing a bit or even level toward the end, then its something else


as far as the exhaust note...for a lack of better description, my car sounds like a WRX at idle (heavy and throaty)...then a bit more high pitched and raspier at higher rpms...I assume it gets really strung at higher boosts... I was too chicken **** to go above 7000rpms because by EBC wasn't holding boost...but when I get my car back ...I will make a vid once its all broken in and tuned

Yo Miraiz... Firstly that is a heavy set up u got there... Respek!!

On the same note... I'm just about to install a Max Rev kit.. and I wanted to know what size exhaust is recommended?

I've got the MR downpipe > No cat > a silencer > then a 5Zigen Fireball Muffler... At the mo the piping is 2.25" I think... Would it be better to go for 2.5 straight through from DP > Muffler or 3"???

Cheers.

The turbo n1 will work good, but the N/A n1 has a pretty small inner diamter on the core of the muffler. It WILL make a difference going from the n/a to turbo...

Zentrae:
you still have a cat?? if so, thats your biggest problem.

ZentraediEK

nope, no cat. just the flex pipe and the rest is all N1 N/A piping. Would it be worth it for me to get the N1 turbo muffler? Get rid of the whole N/A setup(piping and muffler) and get 2.5 inch muffler shop piping with the N1 turbo muffler?
Thanks

mrod006

so, would it be wise to increase the stock piping to 2.5 or 3 inches and keep the n/a muffler?
