can anyone tell me a good cat back for a 92 525i? ive been looking around at brands such as remus and flowmaster but i cant find any that will fit

Stebro & B&B make bolt on set ups.

I had & have both

how much hp would a system like that add? do you know of any brands that are cheaper like 400 dollar range?

nothing cheap is even going to be comparable to the stock setup. The stock setup is really the best. and its free. If your looking for power, then its gonna cost more then 400 dallars. But if you just want to hear the engine, a simple resenator delete will liven the exhuast up quite a bit. While still staying roucghly close to the stock setup. thats my .02

don't delete the resonator. unfortunately, you don't have a 540 and have less displacement and without the insulating and reflective components within the exhaust pipes and chambers, you'll just create annoying rasp.

Unfortunately, I don't think it'll add any to much hp to your car (unless you do some other mods to compliment it)

How much is it for a shop to weld new piping for a magnaflow 14815?

I did the resonator delete with magnaflow 14815, no rasp. It sounds awesome, nice and aggressive when getting on it, but almost silent just cruising down the interstate.

I was charged about $350 for them to cut the old system out and custom bend the pipes back from the cat. The magnaflow is a tight fit but I did not need to do any cutting around the rear skirt. No signs of melting plastic either.

I would just straight pipe it past the resonator. Cheapest also. You will gain a little hp no matter what route you take. Remember, anything that will restrict exhaust flow will cutdown hp. But don't expect too much gain from it.

Oh, and backpressure is BS.
