I removed the NA exhaust from the back flange of the catalitic converter. I then made a "Y" piece to mate the single pipe flange plate to match the twin exhaust pipes. I then cut the end off the turbo intermediate muffler and fitted the "Y" pipe to the cut off pipes. Then I just fitted the turbo exhuast in place of the single exhaust. All the rubber hangers and the like line up perfect.I started the car and was impressed by the way it idles. A bit louder than normal, deeper than normal, similar to a turbo deepness. Then I reved it. Sounds sh*t! Like a B&S ute sort of sound. I hate it. Too loud and then it crackles back through the exhaust on decel. Took the car for a run and it sounds good for a bit of fun, but I certainly couldn't live with it! At 100km/h its loudish in the car. no good. Damb I was hoping it would sound good. Here are some pictures of the exhaust at this stage but I am now going to make a "y" pipe to fit to the back of the NA intermediate muffler and just try the turbo rear muffler and tail pipe. I will get my XR sounding good yet!It certainly did seem to improve the performance of the car so that's one good thing. Seemed to realy start hauling at 4000rpm. Will keep you posted.exh1 Link to comment Share on other sites More sharing options...

Thanks to the guy who welded it all up and made it perfect so that it bolted straight up! exhaust tip was level too! Link to comment Share on other sites More sharing options...

Rodderz Member 92 Member For: 21y 6m 13d Posted 04/04/03 03:42 PM Share Posted 04/04/03 03:42 PM I guess by fiddling with the exhaust somewhat u could eliminate that droning that u mentioned at 100km's? Maybe a few nips and tucks and work on the in-line features such as muffler, resonator etc may make it sound better and run smoother? Link to comment Share on other sites More sharing options...

B) it is good working where I do and knowing the peole I do! The exhaust guys were most helpfull, as they also have NA XR6's and all versions will be tested to see if they pass interior noise limits and also possible factory exhaust upgrades for the future!we have been working flat out on the brake shudder issue, but I'm not willing to say much else. I like my job! many things are being tested as we speak! will keep you posted on future exhaust mods. A good mod for the BA standard 5.4 v8 is to fit the turbo exhaust. gives it a real nice note. better than the xr8's in my opinion! Link to comment Share on other sites More sharing options...

Have you guys at Herrods figured how to get into the ECU to release more power? As Chris has found the exhaust made no difference if no other mod to the ECU was done!
