6G Celicas Forums

I was looking online for a high-flow cat for my car & I came across this... http://www.randomtechnology.com/toyota.html - If you notice, although they dont list one for the 6GC, they DO list one for the 2.2L 1994 Camry (p/n 183-25004)... 5SFE right? So that leads me to the following questions...


1. Has anyone tried bolting this thing up to their 6GC?

2. Do the 6GC/Camry use a common exhaust manifold?

3. If so, then the Camry HFC listed on RandomTechnologys website will work on a 6GC, right?

4. If not, is it possible to just swap the entire Camry/HFC combo in place of the stock 6GC components?

5. Or is the OEM 6GC exhuast manifold a higher flowing unit than the Camrys, thus negating the performance gains of the HFC in the first place?

6. Is the Magnaflow HFC ($800!!!) the only other alternative to the one from RandomTechnologies?

I have a Magnaflow HFC on mine and it wasn't anywhere near 800 bucks. I got mine installed for like 250 if I remember correctly.

crap, your right. I was looking at "msrp". Thats not too bad then.

Is there any slight performance gain with highflow cats?

The issue is whether or not it's a direct-fit catalytic converter. If it sits directly below the exhaust manifold and acts as a collector, then the Camry version will not fit on a Celica -- our manifolds are different. Since the part numbers are specific, I would expect those are direct-fit items rather than universals which can be welded into any straight pipe.

just a little advice... backpressure is not bad on a N/A car... there's potential to lose performance if your system is too free flowing
