Soon-to-be owner of an 88 325is

[hello9821]

Hello,
I have spent months searching, and have finally found an affordable 325is in good shape. Naturally I have a few questions. I would like to do some performance upgrades, and assume that a tuning chip and cold air intake would be a good start. In my travels to a junkyard, I spotted an e30 318i with Magnaflow exhaust, and i was wondering if there's any chance that this could easily replace the stock exhaust on the 325.
Thanks,
Matt

from what Ive read the CAI doesn't do anything to these cars I've been searching for a chip also but I am questionable of which one to get the previous owner of my e30 put an oem bmw exhaust on which it sounds really nice not loud but not quiet headers are an easy bolt on

Would require cutting and welding...

Also If you d an intake and exhaust with a chip you'll notice a gain just a CAI wont do much I sugest a K&N drop in panel filter... Any pics of the beast

For a chip I would look at Jim Conforti (Shark), check out his website.

Dinan chip works well on premium... CAI does a bunch of nothing for the money. The BMW factory intake is a CAI and is very unrestictive even with a paper filter. Same can be said for the factory exhaust... I find that the factory exhaust has a wonderful note that is hard to improve upon without annoying loudness or drone... unless you want to spend a metric ass ton of money on one. You can strait pipe the cat and that would help a little. The chip is definitly the biggest bang for the buck and without major mechanical changes, you won't get much more out of the factory system aside from spending way more than it is worth for the few little ponies you'll get.
