Cars and 82 rx7 gx

I plan on upgrading my stock exhaust here in a couple weeks and was searching around on teh web. and i think i gonna go with one of the racing beat hi-perf exhaust sytems.

but i dunno which exhaust to go with the normal one with teh header/collector, presilencer, and powerpulse main muffler. OR the street port exhuast system taht comes wiht teh road racer header, street port centre section, and the power pulse muffler. It says it can be used on non ported engines with good results, but will it give the same results as teh first or or better or worse? i thought i should go with this one in the event taht i wanna port the engine in teh future. Or how hard is it to port the engine/ can you just do the exhuast port? cause i not rich and can only do a couple things at a time, then ima start lookin at teh intake later and maybe port taht. If i thinkn wrong jsut yell at me so i understand

The part number on the first exhaust is 16413
And the Part Number on the second one i said is 16422

Or how do you think i should do the exhuast, ive been reading archived / older posts on exhuasts to try and enlightn myself a little more. And couple said to use the RB dual exhuast which i am assuming is the road racer header. (might be out to lunch)

Also teh muffler is a cat-back muffler correct?

thanks for helping a noob out

 

holy bad spelling on simple words

 

first of all, spelling goes a long way with getting people to help. Next, I have the full StreetPort system on my stock port/stock carb FB and it's great. I had it on my old stock port/RB Holley 465 setup and it was amazing on there. sounds nice, not too loud, and flows really well. Go with the street port system.

 

ok thanks you whitey, thats all i wanted to know was if it was good wiht teh stock ports. This way i can still port the car and not have to peel out more money to get the exhuast if it should have it.

And wow was my spelling ever wrong, i will take more time next time to make sure my words are spelt more correctly. thanks

 

Go with the streetport version. Sounds better.
