Supersprint

[+49]

Ok after bit of research of the best way to get the V8 rumble and roar out of my 2002 4.6IS

First i thougth it would be a simple x-pipe mod but it seems x-pipes and straigth pipes loose torque in the mid-range which I dont want on a car where the driving style needs torque,Plus for some reason I read x pipe on a 4.6is gives hardly any noise difference..don't get me wrong I don't want it so its undrivable but I want it loud! Atleast e63/sl55 AMG standard maybe 10-20% more.

Anyhows I been looking at back boxes...Seems best way to get alot of noise and not loose performance (if anything gain a few hp) problem is I love the boxie rear style on the 4.6is tailpipes the tailpipe porn IMO ..My mechanic said he could get me some cheap backboxes of a exhaust maker he knows and cut my tips off and weld them to fit giving the same look.For around the £200 which isn't bad.

Then I looked on google.I see a supersprint backbox same style at mine on offer for under £500.Now I allways driven BMW and know supersprint have a big following.Problem is I cant find one video of one to hear the sound?

Can't even find any decent pics of it fitted?

Any help guys? I'm willing to shell out the extra bucks if it sounds great but if its too quite i'll get the custom stuff made up for half the price.
