What is a test pipe Evo X?

The ETS Evolution X High Flow Cat Test Pipe is a direct replacement of the factory catalytic pipe. This has been dyno tested for a 10-15whp increase over the factory catalytic pipe.

What is a racing test pipe?

They are metal pipes that replace the OEM catalytic converters. One of the largest restrictions in the exhaust system is typically the catalytic converters, and by replacing them with a straight through pipe, you can free up the exhaust flow dramatically.

What is an open dump downpipe?

This downpipe features a vent to atmosphere wastegate dump for an intimating sound at wide open throttle. This downpipe has been engineered to be one of the highest flowing downpipes on the market with a CNC tapered flange that matches the turbine outlet perfectly.

Do test pipes make your car louder?

Anyhow, the 3″ test pipe made it sound so much better, no rasp/rattle, etc, and it was actually quieter. So, if you have headers and a 2.5″ exhaust, yes, it will make it louder, even if it’s resonated.

Do you need a tune for high flow cats g37?

No, it’s not absolutely necessary to get the tune but it does help maximize the gains from your bolt ons. The Uprev tune runs around $550 so be sure you’re completely done with your mods before getting it.

Is a test pipe the same as a downpipe?

It is normal to confuse between the two. The test pipe comprises a small section in the exhaust system where the catalytic converter is located. On the other hand, the downpipe is the exhaust part that connects the turbine housing to the exhaust tip.

Are test pipes illegal?

Unless you know exactly what you’re doing and have big plans for your entire exhaust system, we’d advise you to steer clear from test pipes. Firstly, they pollute a lot, and secondly, they’re illegal to use on street cars in most locations. The way we see it, it’s just not worth it.

Will a high flow cat trigger a check engine light?

Typically when installing a higher flowing catalytic converter you will gain some extra exhaust volume, usually around about 15-20% louder without any other changes to the exhaust. The other issue to deal with is going to be a check engine light and a P0420 engine code – Catalyst efficiency below threshold.

Do test pipes make a difference?

The way we see it, a couple of ponies here and there don’t really make a difference. And besides, test pipes will just make your exhaust obnoxiously loud and the drone will drive you nuts on long drives. If you really want to make your exhaust louder, there are other, more legal ways to go about it.

How much horsepower do high flow cats add?

A stock exhaust might be restrictive to the full power of a high-flow catalytic converter. In fact, a high-flow catalytic converter is ideal for a car that’s turbocharged or supercharged. Before adding a high-flow cat, your car should be able to produce 20% more horsepower than its stock setting.

Do I need a tune after high flow cats?

No high flow cats do not require a tune. As you are well aware, they will be optimized with a tune.

Will a cat back exhaust pass inspection?

No problem installing a cat back exhaust system. The smog inspection does not inspect the muffler or exhaust system after the CAT. The catalytic converter, on the other hand, is inspected and must conform to your vehicle exact year, make, model and engine size.

Will a car with a Catback pass emissions?

It’s a “catback” exhaust, meaning it’s sitting after the catalytic converters, so it shouldn’t affect emission.

Does test pipe change sound?

Do resonated test pipes make your car louder?

End of dialog window. Test pipes will absolutely achieve louder and raspier. If you’re just wanting the power, try resonated test pipes, they are just as cheap, more/less. My friend had Berk resonated test pipes with AAM short tails.
