Hi Guys this is my first post on this forum.Its fantastic to be part of this forum

Decatting the car without changing the rear silencer will it make a decent
power gain.

Thanks

Yes it will.

Expect anything around 18-20 RWHP.

We have dyno graphs if you'd like to see them.

18-20 rwhp, nice gains!

What about the noise? Does the car gets too loud only with the decats/test pipes? This is always my main concern when it comes to upgrading exhaust systems.

18-20 hp?

that seems like a lot, why isnt everyone doing it?

It does get slightly louder.

We will take some videos of some racecars that run stock rear mufflers but with complete decat and X-Pipe.

I've removed the primary cat, definitely "feels" like about +20WHP, even if it is really only +10-15WHP the mid-range torque is definitely a lot stronger.

Sound wise, normal daily driving you can't notice any difference. Going WOT the car is slightly louder with a bit more rasp. Sounds great though...

Definitely the best bang for buck mod!

Get it on a dyno.... you might be surprised by the result...
