hey what is a good set up for an rx7?? single exhaust, fake duels or true dules?? im asking hp for weight/ tourque differences for the money??? not how it looks or why it is degrating to make it single cuz its taking away its uneakness im asking pure preformance. so what do you think is the best preformance exhaust including width of piping and all

 

If you have the cash, true duals would be pretty good. Im opting for a single (RB header/high-flo cat/CS catback) One because of cost, 2 because of weight. The duals are fairly heavy. True duals would net a broader HP and TQ range, but a good single will be very good also.

 

how much are Cork sport mufflers

 

The muffler itself....$89. The entire catback is only $289 though..

 

duals!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

duals

 

yea but i would think the preformance for price factor has to fall into that one i mean over 1G for and exhaust system thats way to much

 

haha

Well there you go. This is the best HP on a stock engine. IF you want bang for the buck then fab up some singel exhaust with a 50 dollar muffle from ebay and thats it.

 

i mean i want preformance but 1g is ediculus for an exhaust system thats all im saying

 

it comes down to $$$ duals will flow more, and adds turbulence, also 2 time as much as expensive....though a single is cheaper and allows much more straight through performance for turbos.... 3" is enough for a 60-1...............

 

seems to me that the slight HP improvement with duals would get cancelled out by the extra weight. You'd be surprised how much that tubing weighs.

 

im going with a little bit of both, i bought the RB road race header, and i bought the RB collector to bolt up straight to the header and from there on out im getting 2.5" piping all the way back to a A'PEXi N1 muffler! i hope it sounds nice, i got my header on already, just waiting for the N1.

 

Even custom Y pipe "fake" duals are heavy. I had to change the spring perch height on my rears when I went to the single. *** end was sticking up from the lighter exhaust.

 

look the reasons I bout the DUALs are:

1) They are the BEST for a stock 13B which i have
2) They have big HP numbers recorded on a dyno
3) I hate the single exhaust look
4) I wanted to get the best I could with the money I had

The results to date:

1) They are awesome
2) sound is great and not hella loud
3) It does not sound like a lawn mower like people told me
4)They look great very close to stock size)not a big grapefruit cannon tip like N1's
5) I loved the fact i did not have to fab anything up
6) Easy instalation even alone with limited tools
7) Compared to the stock exhaust the weight increase is minimal
8) I have already compensated for most if not all of the extra weight with removal of crap(radio, A/c, Emmisions)
9) I kick a lot of *** now and get respected by fast cars when I drive around(not that i care though)
10) I love them PERIOD and they DID NOT disappoint me at all.

 

I for one am a fan of dual exhausts, what are you using the car for? Is this "just" a street car or something else? Also...ANY exhaust setup is GOOD (when compared to stock) including the pacesetter exhaust.

 

True duals suck. I wouldnt recommend them to anyone. And I cant wait to get rid of mine...

 

Whats wrong w/ N1's 87. The fact that all the Japanese supercars use scare u or something? Just asking. I love the deep mellow sound of my single and it was only 500 w/ shipping.

 

well they are huge. Wankel7 tells me the tip is 4.5" that is hella huge yo. I like the Duals cuz they are not BIG like all the hondas around here. and if it is the single I have already stated my position on that many times.

 

For what reason do they suck? I would really like to know. I have not had anything go wrong with mine. Let us all know.

 

Its not the fact that hondas use them its the fact that their hondas and their slow, what about skylines that use them or silvias or RX-7s or Supras?

 

I mean I would like to separate myself from the fart cannon look.

 

then stay stock... nobody does that anymore.

 

haha You know what I mean the RB mufflers are not huge and my car is still fast without. Oh and it is quiet too and a deep rumble sound.

 

why does the N1 have to fall into the fart cannon look category? just because its big doesnt mean its a fart cannon...the N1 is definitely not a fart cannon, and not many ricers have them that i know of, because they arent willing to spend that much on sound, besides...it doesnt have the sound they are looking for, its too deep for them.

 

i have the corksport single exhaust, its a good piece, stainless all the way through, and the piping is huge. its deffinally lighter then a dual setup, but its really loud, on my car. (sometimes good, sometimes bad) =)

its all a matter if u can what it looks like from behind. and how much money you have to spend.

 

I said look. I have not heard the N1's in person but have seen videos and they are ok for sound but not my style for size. My exhaust is modestly sized. I think that 4.5" tip is crazy specially for the N1 duals there is no need for them to be that big.
