try the greddy evo... i love it, not much drone for an exhaust... did not not even notice any drone until i floored when i need it... it felt like it flowed better with a k&n drop filter just recently installed...

I am going to stick with my stock exhaust, but may go with Berk Tech HFC later on. I am keeping my car NA and been happy with the mods I have.

In future may look at different wheels.

I have a Borla on mine, and I do agree with a slight loss of low end.

In daily driving, up to 2500 feels a little sluggish with moderate throttle, but it may just be because of the hot weather.

I've noticed that the Borla is a good big louder if one is sitting in the passenger seat as opposed to the driver's seat. It's funny, but it got quite annoying sitting in my passenger seat listening to the exhaust drone for two hours as my friend took the wheel. What made me laugh was that whenever he let off the throttle I could hear and sense a slight pop. It sounds sexy, but it is a little annoying.

However, I did feel some top end power. I think from about 4500 up, especially 5000 up, it feels peppier and the tach swings to red line faster.


I don't mind the exhaust, but I will be upgrading to Motordyne when his sedan system comes out.

I would like to thank all the forum members for all your taughts on the "best" bolt-ons for our sedans. You all have made good suggestions to me. As of now, I am very happy with the mods I got, per your suggestion and comments.

I am going to now cruise and enjoy my slightly modded GGG Sedan.



Future Mods:
1) Berk Tech HFC
2) OEM Front Lip
3) Tune/Dyno

I have the Stillen Gen II, the drone @2500 was still obvious & obnoxtious.

It doesn't make much difference in power at low speed. But at high way speed,
the increase power over stock is obvious when passing etc.

I fixed the drone by adding a pair of "cc insert", Google "CC muffler insert"

I fixed the drone of gen 1 with a "b-quiet" mat, Google "b-quiet"

Do it. Enjoy the car and the little tweaks you do. It's very easy to get caught up in going to the next mod, then the next, etc. without enjoying the difference each one makes. Do all the mods too fast and you'll grow board quickly and/or you might choose mods that really aren't that good and lack data that they actually work. This is coming from someone who has been burned quite a few times hence the reason I so damn critical of aftermarket claims, both vendors and owners.

Motordyne sedan system?
