I have been reading and looking around the forum on exhaust upgrades to the XK..So let me beat this dead horse one more time guys. While I am not in the market at this time for a new exhaust system. I would just like to understand it a little better. I love the sound of the stock XK exhaust, I also wouldn't mind if it was a bit more deeper, throatier either. I'm not really looking for HP gain, otherwise I'd be in an XKR or adding a twin screw. But I wouldn't mind helping the engine breathe better and if that adds a few ponies, that's cool.

I keep hearing of Borla, Mina Galleries, and a stock XKR set-up. I like the looks of the twin dual pipes out of the back and I believe all these would offer that. Would I need to buy a different lower rear bumper part to accomadate sp? the dual twins as I just have duals now?

I've looked at the Borla website but do not see a version offered for the 07 XK

I've looked at Mina and wonder if it really is an upgrade over a stock XKR set-up?

and is a stock XKR set-up deeper and throatier than the XK sound? I've also read about just doing a rear muffler delete, not sure I want to go that way?...also read that just changing to hi-flow cats will have a more aggresive sound?

Maybe change headers and cats in the future, mainly interested in the cat-back option...what ever input ya'll have to steer me in the right direction is much appreciated.

ya no!! i dont think eleanor roosevelt siad that!

 

changing the cat back with make the car sound deeper and it will breath better especially on the hwy. the cats will open it more and have a better growl.
