Can you use SLP High Flow Cats as the pre cats connecting to BBK X-pipe with BBK Hi-flow cats? I searched every where and i cant find another pair of high flow cats and the only thing i can find is a slp high flow cat, so just wondering if i could use two different types of high flow cats together...

SLP being the pre cats position, and the bbk hi flows are near the mufflers in the back.

Let me know, been trying to get this right and I just keep getting ripped off by mechanics and muffler shops.

Currently I have some 3rd party flow muffs, BBK X-pipe with high flow cats (still stock pre cats connected but there bad and need to be replaced) < - so thats why i want to know if I can use high flows in the pre cats spot and also if i can use SLP cus I can not find bbk high flow cats. Faling emmisons 4 times over ina row sucks.

Thanks for the replies mates!

 

Looking for a fast response and i dont think ima get it.

 

No real reason why you should not be able to. I wonder though, is there a visual inspection in GA? You should be able to eliminate all but two and still pass emissions...not sure about a '95 though, 5.0 engine?

 

No You can't use.
