Exhaust Opinion
 

Currently I have Kooks catless headers to stock NPP system. I just dont love it like I loved my 5th gen set up like that.

I am thinking about putting the stock manifolds and primary cats back on and switching to the Corsa extreme setup.

What do you all think of the two setups?

I have the Corsa Extreme + Catback exhaust and absolutely love it!!

You will lose power though by taking off your headers and going back to just a catback exhaust.

Im planning on installing headers to go with my exhaust and getting a tune

What do you not love? the volume, or tone?

Weld some resonators in the X pipe and you will like it a lot better.

I put on an AWE Touring catback and it's fantastic. No valves, but I never used the valves on the stock exhaust. There's a very, very small drone on the highway at 2k RPM

I have the Borla Atak with X pipe and Gesi UHO 1,000hp Cats and Stainless Works headers and just love the system. Zero, zero drone and the NPP valves on the Borla work great.

I have ZERO drone with the AWE resonated touring catback. Maybe you need resonators to eliminate that.

I have the same one, and LOVE it... but it was too loud for me even with HF cats... I ended up adding the MF X center muffler to tone it done.

I have Kooks catless headers, and I have some additional resonators in place of the smashed section by the axle. I just dont love the tone/sound like I did from my 5th gen.

Sound level is not the issue, its the sound itself. The resonators I put in did help a lot with the raspiness, but a lot of my research has led to changing the muffler setup.

Many people don't love the sound of the stock catback especially with the cats removed.

Which resonators did you go with?

I do indeed have non-resonated.

Put an AWE Touring axle-back on it and it should be fine.

I have Kooks headers WITH cats to the stock NPP and its one of the best sounding cars I have ever owned.

Big mistake to not go with cats in a performance exhaust system. I have never heard a car that was catless that did not sound like garbage.
