High-Flow Cat Question....

Romanowski · 08-02-2009, 07:45 PM

Really n00b question but..

I have been reading that High Flow cats give out an unpleasant exhaust smell. How bad is it?

I know its "Illegal" for street use

. If its fun its more than likely illegal.

I plan on doing the popular bolt ons within a few weeks. IE: Stillen Intake, High Flow Cat, & Exhaust.

Suggestions??

As long as you're in your car, and not standing behind it, smells just fine.

They don't smell bad, it's the test pipes that smell bad.
I think they are a few popular bolt on's
Berk HFC
Stillen GEN 3 long tube intakes
Berk CBE or F.I. CBE
Thats whats selling

Can I piggyback on this thread? I don't want to start a new one.

Has anyone here ever gutted a HFC? I'd imagine you just end up with a resonated test pipe of sorts?

In certain states it is illegal to change the stock cat.

Humm.. good idea, what about the backpressure change? Loss of power?

Meh...

When I got busted for running an Off-Road X-pipe on my Mustang I bought two cheap cats, sliced them open, removed the guts, and JB-welded them around the O/R X. Painted my welds silver and convinced my dad I installed HFCs.
