Just searching around on eBay and I came across an OBX Cat Back exhaust. I searched and can't find any reviews. Does anyone know about or have this exhaust. Any input is appreciated. Thanks
From what I've seen, OBX stuff is actually pretty quality, especially for the price. The name doesn't carry the prestige like the bigger names do though.
Someone is gonna have to dyno the OBX: before & after. My guess is it does make more HP, 2-3WHP. The one thing that is measurable is OBX tube diameter is 2", Magnaflow is 2.25"/2.5", definitely more flow.
I put an OBX on my 325i just because i was on a budget and it sounds really good and you can see the tips come out and see the muffler if you look around. Wasn't much of a hp boost but still great for the price. Ill post pictures later
Great thread. I was considering the same. I plan on having my daughter's clutch replaced and was considering getting the OBX cat-backs installed at the same time.
i dont have any headers but my car is being repainted right now and will be done next week(will make a thread about that!) so ill get sound clips next week and post them here. Ill attach a photo of what the tips look like on my car. For the price its a good system, sounds nice and isnt too loud.
I had the OBX exhaust from the headers up to my rear AA muffler (so I basically used the OBX front x pipe and second resonator). It's a direct copy of the supersprint non-m exhaust system. I ran it for almost 70k miles, and it developed multiple cracks around the x-pipe and resonator. However, my car was making 300+ whp at the time so it was flowing much more than a regular non-m. I've also cracked the eBay headers at the collector before, and have since switched to a full legit exhaust system. For the $$ you can't beat the OBX, but if you're making any sort of power I'd just leave the stock midsection, change the rear muffler, and add headers.

Just Realized that im runnin an OBX... Had the car in the lift the other day and saw the label that was hiding from me all this time.... lol. Dont know how i missed this.. I have it on my 323ci since i bought it. I do not know HOW LONG its been on the car, but ive been running it for 3 years now and actually really like its sound. Keeps that FACTORY feel and wraps it with the performance sound.. Dont know if that makes sense, But let me just say, I AM NOT a fan of the fart can that get glued on ALOT of kids cars... As far as price, I looked mine up, and 600+ seems fair to me. Mine has a different straight pipe though. I swear im close to 3''.
Please post more pics and sound clips!
I am looking at buying this exhaust set up for my DD/Street.
I do not plan on tracking at all and think this would be a nice budget addition to looks and sound.
I have had the OBX catback on my 2001 330Ci for almost 2 years now, but only about 10-15k miles. I was very skeptical about buying an "eBay" exhaust, but it was a mid-range price so I took a chance. Very impressed and highly recommended.
THE GOOD
Looks great. Not cheap or ricey.
Direct bold-on (except possibly extended exhaust hangers)
Sounds great. Very deep rumple. No raspy-ness at all.
Almost too quiet when I first installed it, but I think it has gotten louder over time.
THE BAD (all minor stuff)
There are these thin little tabs of metal that are welded on to secure the 2 exhaust tubes together in a few places. The welds broke and the tabs started rattling. I simply pulled off all the tabs; they don't appear to be needed at all.
The exhaust tips are too high and melted my bumper. Only noticeable if you look up close or from the bottom. Extended exhaust hangers needed?
The round exhaust clamps that connect 2 sections of the exhaust seem kinda cheap, one got all bent up and had to replace it.
