it really sounds MUCH better then the video.. i guess my camera just really sucks...

 

Sounds nice to me

 

Can someone tell me why testpipes are in that shape? Would'nt a staight piece of pipe sufice?

Riz.

 

Sounds good

 

sounds good man. btw thos kicks are sick man!

 

Most "test pipes" are larger in the middle because they pack them with a sound dampening material (basically a muffler) to make the RX-7 slightly quieter. I don't think it sacrifices any flow or velocity compared to a straight through test pipe, if so it's minimal.

 

THNX for that info!

Riz.

 

Also, it looks like a high flow cat... So, if you get pulled over and the cop pulls out a stick w/ a mirror on it, they will see something that looks like a cat... Although we dont have emissions here in Florida, BSO does that kind of crap all of the time to pile on the tickets...

 

thanks guys.

but yeah.. it basicly is a pipe.. exept it bolts strait on and it looks like an actual cat so caops cant really give you ****.

 

no editing done.

 

Yeah, I love shooting fire.

My injectors leak like a ****, so I constantly run richer than I should. That + straight pipe = winner at backfire competitions.

 

i have the same obx exhaust but for it can fit cause it was short 2"inches so i had to make a adapter to fit the header which is a pacesetter brand.

did your's bolt on or what?

 

let us know when you get your first ticket.

 

u gota pay to play man. or in this case burn!

 

cant wait til mine does this

 

How big is the tip? 3" Looks nice, sounds good and the fire is even better.

 

mine was a little to long so i cut about 2 inches off and welded the rest back together

 

i think its 3.5inch tip

 

wait, so I am thinking of getting the RB presilencer (cause otherwise this **** will be too loud!) and this exhaust.

I read that it's supposed to delete the cat and bolt straight to the header.

You said you cut it a bit and rewelded it to fit the test pipe, right?

 

does anyone know if the OBX header bolts to the stock cat?



Its also going on a vert if that matters.

 

Be careful of what you replace on a NA exhaust, replacing some bits can make the 5th and 6th aux ports not function.

 

Decent exhaust! Really makes those flames come out.

I wonder if that test pipe would go into the racing beat system in place of the precilencer, probly not because it looks a little small.

 

yea i plan on keeping the stock mufflers on my N/A they are fairly new and not the slightest bit rusted

 

im going to make this clear for all its not a cat back its a down pipe-back exhaust

for some reason its not made right for the rx7 for it can bolt up got to make a adaption

 

ICEY? : Can you post some pics of the car from a few angles? Also, is the piping 3"? how does it fit on the Resonator? (I have the same one). Thanks.
