Jut after opions on a full exhaust system for a ba xr6 , I'm looking for a deep note should I even try a 3' turbo exhaust ?

A quick search will show results, but I'll let you know regardless.

First off, you're going to need extractors if you want it sounding nice. You can get pacemaker 4490's off ebay for about $300 brand spankers. After that, you can either go with a high flow cat, or not, it's up to you. Now this is where it becomes personal opinion... lol

I first used a single 2.5" Mild Steel Redback exhaust, with 1 muffler. It sounded nice, but was overly loud (gets annoying to be honest...)

I then swapped out, and went with Pacemaker 4495's, Venom Cat and twin 2.5" XFORCE with 2 Mufflers. It picked up more torque down low with the 4495's, and breathed a lot better up top.

The sound on the other hand, was second to none. You could barely hear it at idle, or at cruising speed as there was no drone what so ever. But give it a boot, and she growled so deeply, it put a smile on your face.

Do a youtube search to hear some systems.

I got the pacemaker 4495's and straight cat with single 2.5" xforce and same as above,
No drone no noise at idle or crushing. With the exception of a cold motor at idle, but when
You give it a boot it makes a beautiful sound!! Mild steel.

Thekrazed, how much did twin 2.5" cost you?

muffler magic are great they did me a cash job for 600 with full 2/5 wildcat and high flow cat that sounded great... so get extractors and go there they did a great job

The twin 2.5" was $600 for the catback. All up I spent around $1200 for the entire system + install.

Only issue I found with it, was that it was very tight fit around the rear axle, so it rattled a bit. Nothing a bit of extra welding or even a rubber stopper won't fix.

I've got a full Di Fillipo system on my BF, I think it sounds great.
Im in Warrnambool a fair bit if you ever want to hear it.

Pretty much anything that has two proper mufflers will sound good with out drone.

I have X-force Headers and high flow cat into a Redback 2.5'' system with 2 mufflers on my BA, and to be honest i think its a bit too quiet. It opens up a bit when you boot it but not like ye olde E series one muffler setup.
In saying that though it gives a nice bark sound on backoff Thinking about getting the rear muffler removed and seeing what thats like.
