single.

either the opak-r titanium one if i feel like a baller.

or more likely a custom 3" with a muffler and resonator.

 

I went with 3 inch single, and I lost some torque. So I went back with 2.5

 

back to back dynos?

 

no, but I sure felt it. I lost races to cars Ive beaten with 2.5, unless u are S/C, then go with 3. But the only way u will gain alot of power with 3 inch and stay N/A, is if u go all out and get full bolt on mods, and other goodies to back up the 3 inch. I dont have alot of performance mods, thats why Im faster with 2.5 than 3 staying N/A. Alot of people on this site will tell you the same thing. They told me all this too before I made the mistake of going with 3 in the beginning and didnt believe them. But if u go all out with mods, go for 3! To start off, for gains, you will need ATLEAST header, CAI and exhaust.

 

also, if u get a resonator, it may restrict some air. But on the other hand, it would help the sound not be so loud.

 

well as long as no power/tq is lost in vtec i could care less about the low range. my last car was a dodge and it had a vtec powerband i'm used to it.

and both the muffler and resonator i'm getting are perforated core straight through designs. they hardly restrict any if you're at wot.

 

oh ok, thats cool then. If u are more concerned with VTEC, then yah go for 3. Just to warn ya, she will SCREAM in VTEC with 3 inch! Made my ears almost bleed! I even scared a guy in his stang when I dropped it down to 3rd on the freeway right next to him. He just about jumped out of his seat....lol! Also, if u can get away with it where u live, use a test pipe to replace your cat converter if u can. It will help your 3 inch too! Id recommend T1R or Berk test pipe.

 

sounds great

 

i would be running a 3" test pipe too. which eventually would mate with a custom header with a 4-1 merge collector

i hope she screams. i want civil while driving casually and a screaming vtec

 

haha! oh hell yah you'll get exactly what u want with this setup! Just watch for cops before u make her scream. Makes ur ears bleed, but its also music to your ears
