430 Test Pipes - One better than the other?

Guys,

Is there such a thing as a best test pipe for the 430 coupe? I've been surfing around sites and can't seem to differentiate between what all the brands are offering. Tubi, Capristo, Supersprint, Novitec, Fabspeed, Agency Power etc. Is there one test pipe that stands above all in terms of build quality, sound enhancement and performance gains?

Supersprint seems to offer a straight pipe with no cats. Not sure how that'll prevent the CEL from coming on. Cheap though.

Capristo offers a flexi cat which is still basically straight through so not sure whats the point of even having one at all. Perhaps it is to reduce the flex tension stress on the stock headers.

Fabspeed has two variants. One is a cat bypass so I believe this is fundamentally a straight through, ala Supersprint. The other is a sport racen high performance cat which is a high flow cat but not straight through? Hmmm...I'm confused. Price difference of almost 1.5 grand.

Don't wish to talk about Novitec coz I simply can't afford it and somewhat I suspect they are basically Tubis underneath.

Ok, so what I am after is the highest flow, non CEL activating test pipe. Please tell me there's such a thing. It's gonna be fitted to the factory headers and capristo twin sound with remote controlled vacumm valve.

Thanks

 

Thanks for the tip. I intend to leave e headers stock but put in test pipes to give the twin sound more kick. Sports cats make lots a sense though. I'm not sure how much sound I'd be losing between test pipes and a 100 cell sports cat though but I guess not getting the CEL would be a big bonus.

 

Ssr, is that the test pipe or sports cat?

 

You must have misunderstood my intentions, never for performance, it's more for the soundtrack. But good tip on the black residue issue. I'll have to think hard about that now.

 

That's what got me thinking last night since my previous M6 was running a full race exhaust setup with race headers, no cats and basically no mufflers, no residue issue at all. Looks like Im going to get supersprint test pipes. Black residue may be the result of poor tuning hence engine runs rich.

 

So perhaps that's why test pipes are better?

 

Is it absolutely necessary to wrap the test pipes? Wouldn't it be less hot now without the cats?

 

You mean this one?

Very very nice. Even the holes for the o2 sensors are precut.

 

So my other question would be, ignoring the cel and the finish of the pipes ( ie stainless versus polished ) do test pipes offer different performance or sound levels? I'm comparing between Fabspeed, Supersprint and Capristo. Prices for Fabspeed and Supersprint are pretty close. Capristo is a tad dearer.

 

Damn...flames? Not sure what's coming out of my pipes now but it sure is loud.

 

Good stuff. I've Fabspeed headers and test pipes now, and capristo twin sound. No intention of going full scud rear ugh my grille and bumper are already on order, so is the scud fronts.

Blue flames are nice...hopefully it doesn't melt the bumper away.
