about to do my exhaust(anothe exhaust question),is it worth the extra to do stainless ,and is there any benefits in having a s/s system?
Iam looking at running pacemakers,3in cat and magnaflow muffler ,and mandrell bending all in 3in piping.

IMO S/S is a waste of money unless you plan to keep your car for 20 years or more.

I believe there are small performance advantages for s/s systems, to do with retained heat, speed of gas flow, blah blah.

I'll agree with Falcoon and say that unless your looking for the last bit of performance (ie me :s6: ) or plan on keeping your car for some time (me again), then it's probably best to lean towards mild steel.

Correct me if I'm wrong, but isn't your car an XR6? If so, unless you're gonna run some type of forced induction, 3" on a 6 cyl is overkill and will actually loose performance. I'd suggest you do it in 2 1/2" mandrel bent piping :s4. S/s would be nice, but it comes at a price.

I believe there is a noise difference between mild and stainless. I once got a s/s header pipe (from stock cast iron header to cat) and it was the worst thing I ever did - the bastard drones like mad at around 100. Plus it looks rusty, so I dunno what's going on.

How do you avoid droning in an exhaust? Mine sort of pulses between loud and really loud at about 1-3Hz depending on speed and acceleration. But I think the weather has an effect (ie. temperature) because it doesn't always do it.

Ryan is correct, a 3inch system on an XR6 is overkill.

Might be to do with the quality of your muffler. I recently got a new "cheapie" rear muffler put on my EB (stock 6cyl system) and now it drones ever so slightly, never used to with the original muffler. Maybe a reasonater might fix your problem.

thanks guys,
many of the exhaust places say mild steel but the more up market say s/s, but i would save my money and put it to my suspension upgraded ,
cheers

Simple answer. You MUST use S/S up to the cats. After that it's up to you.

If this has been covered else where then tell me, not wanting to create another long post on exhausts, but can I ask why MUST you use S/S up to the cats?

I don't mean to question you but the last quote i got was for mild steel Pacemakers. The exhaust guy at a Profix dealership said that they would be fine. I did price both.

Thanks
