I was looking at aftermarket exhausts today would it be benefical to get a whole new system or just hollow out my existing cat and bolt on 2 normal , lets say magnaflow exhausts?

if i were to get a whole new system could someone point me in the right direction of what brand to buy

 

What kind of car do you have? NA? Turbo? I'm more a fan of a whole system, but it comes down to preference.

 

88 N/a Gxl

 

i hollowed my stock cats and im running the stock mufflers on my 86 n/a and i love the way it sounds!

 

RX7.com has a great cat back for you, not to mention race pipes and high flow cats. Quality stuff.

 

i have an 88 GXL too.

my exhaust is a full RacingBeat setup (just not the headers) and i think it sounds perfect. It has a hint of the original sound, but its way more agressive (and it shoots fire )

 

has anyone here used Rotary P
erformance exh
?

 

i dont know how that came out like that

 

Economical system which offers good performance and a low, baritone sounding exhaust note. Our best selling system. Installed in cars producing up to 400WHP.

RP 50mm Cat-back - 86-91


Would this be good for my stock GXL? or could i just make my own , get a high flow cat and 2 magnaflow bottle exhausts?

 

i would go with a full racing beat set up including headers.

 

RB manifold-back.

 

SDJ header (from banzairacing)
2.5" borla xr-1 presilencer to whatever catback you like or just custom single or double sided w/ either magnaflow or borla mufflers


either that or full RB system, header > presilencer > catback or the new true dual system


I'd go the custom route myself. maybe add in a dynomax bullet presilencer into the catback if you run single sided exhaust and then some big borla or magnaflow muffler at the end

 

NODE...

Are you using a borla xr-1 muffler as a presilencer?? How do you like it??
Does it decrease that loud raspy sound from running headers and a free flow cat??

I'm thinking about running a 3" XR-1 after the cat on my single 3" cat back exhaust with magnaflow muffler. Its just too loud right now (headers and free flow cat) and I need something to quiet this bad boy down.
Was also looking at RB's 3" ID universal stainless steel muffler...

what you think?

 

Borla Stainless Catback

racing beat header

borla XR-1 in place of the cat or a high flo cat.

i can vouch for the borlas, other than that i just know people love them

 

I just ran upon an unknown (possibly shop created) full manifold back exhaust for my 90 GTU. It's 3" straight to the Y'pipe with hi-flow mufflers. It was on an s4 vert. I just so happen to work at ISC Racing, so I got it for free. Before I offer my advice, how does everyone feel about the Apex'i N1 Dual exhaust? Good, bad, decent? That was what I was going to buy for myself, but I think I found the best deal for my money. Who can argue with free? And it's about 30 pounds lighter than my stock exhaust with gutted cats.

 

buy the way, we make our headers.
