Exhaust question
 
whats the best size exhaust on a non turbo to go 2 inches or 2.5

classicauto 12-30-05 02:44 PM

is it stock?

rx7legend 12-30-05 03:58 PM

my neighboor has one with 2.5, i hear him coming like two blocks away. but i definetely go with 2.5.

driftfc87 12-30-05 04:01 PM

yeah 2.5 is good

matts86fc3s 12-30-05 06:41 PM

i have a full 3'' meagan racing exhuast... not by choice tho. i needed exhuast baaaadly and a guy was selling a whole s5 loaded parts car with the exhuast on it so i figured what the hell... its too damn loud and ricer sounding, ive got a fully amplified everything stereo system and i still cant hear it!!! sucks. get something with a silencer on it please for your own good. unless your def

Noel Caraballo 12-30-05 07:08 PM

yea it pretty much stock i dont have no upgrades becaause i wanted to start off with the exhaust first. I ll make sure i put a some kind of silencer in it.

Get a 2.5 inch system, its worth it. As for the sound, don't get a silencer, just get good mufflers. If you don't want a loud car, get duals. If you have the money, Racing Beat is about the best you can buy, and it has a nice relatively subdued sound to it. If you don't get the whole RB system, at the very least get the dowpipe/header and presilencer. It will still operate the aux ports (if you have an s4) and has a good sound to it. BTW, I have a good conistion RB downpipe if your interested.
Edit: just saw that you have an 88 so you need something to operate the aux ports, and the RB presilencer is the only one I've seen that reliably operates them.

shoot my friend has a pretty big exhaust on his '88 and I myself love the loud sound it makes when I was racing him. If anything I say make it as loud as you possibly can. The cops might get on you about it (they do around here) but who cares it's still awesome sounding.

if you plan on modding it at all definately go with the 2.5. as for mufflers, i know some borlas are relatively quiet, but dont get glaspak, they tend to do bad things when exposed to the ridiculous heat of rotary exhaust

Sideways7 12-30-05 09:23 PM

Thats a good point, I have heard good things about borla XR-1's. And def dont get glass packs. The fiberglass will melt rapidly.

Its actually somewhat small :).

Just 2.5" then splits to 3.125 single at the y-pipe.

But thanks for the compliment :). But that exhaust is being sold as I'm going with Borla, I need to be able to drive freely without worrying so much about how much noise I make :).

awe that sucks yo. I remember when those bagley kids came out and reved up at us, and you hopped into the rx7 and showed them what they had coming. Oh well noise violation laws suck. I can't believe they still have em.

They have them because of peeps shit canning around Bemidji and the hicks and their n00b pipes. I'm sure my exhaust didn't help that situation either.

My exhaust will still sound nice. Just deeper and smoother (and quieter).

PS: I still love Corksport. I'll use their exhaust if I ever build a TII

thats it i made my mind 2.5 to a 3 half way down with a apex n1 muffler and wire the actuators open,

spot_skater 01-01-06 06:37 PM

Got a cat replacement pipe from RB, bolts up to a RB presilencer...I'd sell it to you cheap...like $20 + shipping :P

Noel Caraballo 01-01-06 08:50 PM

You sure you want to wire them open? It kills low end torque if you do, plus if you get the RB presilencer they will still work.
