Oh yeah, and how is the sound from the high flow cat? It's not annoying right????

ALXVA8

I've been wondering about the same thing myself, but I went ahead and ordered it anyway. I figure like any other exhaust component once installed the sound will calm down over time. As soon as I know I'll write my opinions here.

ALXVA8

G8rboy, what are you using to tune your car? Are you NA or FI?

G8rboy

Still NA for now... probably going to get a supercharger in the next year (probably the Pettit kit, but maybe the Axial Flow if it's released soon enough). I'm holding off on an ECU until I make that decision... but the Interceptor looks like the best bet right now.

Looky what I got today...






Resonated/catless midpipe. Looks awesome, can't wait to put it on. For those interested it weighs approximately 10.8 pounds.

G8rboy

Damn that's purty... looks like quality craftsmanship.

ECHO1

when are you planning on doing the install? you're gonna do everything at once, right? looking forward to pics/clips should you make some

ddub

Maybe next weekend if things work out, but not totally sure yet.

Yah everything at once, OBX header, rx7store resonated/catless midpipe, rx7store catback. I'll get sound clips and pics when it's all done.

ALXVA8

What, not fair. I did not get mine yet! Well, good, I'm glad you got yours then that means that my delivery should not be far behind.

Running richer will damage your cat. Not leaner.

G8rboy

Only in extreme circumstances, like after flooding it... otherwise running lean adds heat to the exhaust gases, which can melt a cat not meant for that purpose. Running richer keeps the temps lower, which is the whole reason Mazda lowered the HP ratings when the RX-8 was released in the US... they had to ensure the OEM cat would last long enough to meet US federal regulations, and is one of the reasons we're stuck with an overly rich tune. It would have cost them a fortune to put high-temp cats on, so they detuned it instead. I think the factory tune has been slightly leaned out over the last few flashes, but nowhere near optimal.

XeRo

there is a god aweful amount of leaning through the curve that can be done on a N/A 8...so far the Interceptor is the only one..I think...that allows us to keep all the safety pieces controlled by the ECU intact and provide the ability to take over control and keep the PCM/ECU happy enough to achieve gains not possible with e-manage and the sort...

Cat Life < Leaner A/F

In another thread...although no one has stated this particular cat...some have experienced melting even the highflows including the SR cat...

XeRo

Jason...back to Epitrocoid's question earlier...is there a way or an option to have an EGT bung placed on the pipe or did i miss that answer?

Jason

We could put one in but the problem is we dont have the bungs here. They usually come with the gauge.

Wondering if anybody who has ordered one of these is retaining the OEM exhaust, or if that's even advisable. If so, please post on your results.

My credit card itches.

G8rboy

So who has installed one so far? first impressions? everything fit up good?

no brakets on these
pipes ?????

Jason

No brackets on the pipes.

Mazda-Rati

If some customers were willing to pay more, would you include a hanger?

ddub

Monkey welds? The welds look pretty nifty on my midpipe... What're you talking about exactly? And 345 is a GOOD price, look at the other high flow cat midpipe options out there. RP (rx7.com) is 395 + shipping and also DOES NOT come with a hanger, and the sr motorsports high flow cat is 399 + shipping and it can't even hold up for very long. What is your beef with the pricing? It's cheaper than anywhere else...

Jason

Are you a welder?

What is the facination with the hanger? Obviously if its not on there you dont need it, especially with a pipe that only weights 10 lbs.

ALXVA8

I can agree with that. Looks like a fine piece to me as well.

Jason

I have talked with the company that makes these and Im going to send you a new one. The first pic that you show, the one with the three bolt flange should not have extra pipe sticking out. That is supposed to be on the other end with the 2 bolt side. They made a couple of these backwards and it looks like you got one. I will have fedex pick that up on tuesday. Since you are unhappy with the welds I can refund you if you dont want it. Send me an email jason@rx7store.net and let me know your full name on the order.

Thanks
Jason
