No its not that. In CA removal of a stock CAT is grounds for a big time fine

Does not matter if you replace it with a high-flow cat. It must be broken/ and or out of warranty to be legal to replace. I am guessing you would not fail an emissions test unless they knew what to look for. I mean headers are headers.

Tony & his guys were such a big help through the whole process and just overall great to deal with, talk to, and do business with.

I wasn't really going for top HP numbers (although I'm definitely NOT complaining at the results).. I mainly wanted to get rid of that awful torque dip.... mission accomplished!

The headers & over/front pipes themselves look awesome.. great craftsmanship.. smooth shiny finish, and functional! Sound-wise, it's definitely louder than stock but not too bad.. Strangely enough it sounds a bit louder inside the car than it actually is from the outside. I love how it sounds now from the outside though.. slightly deeper tone, a bit mellowed because of the stock exhaust, but definitely better sounding than the stock setup.

header looks really close to your intake.... Prob going to heat it up quite a bit.

Na it's got plenty of room.. in fact I'd say it's the exact opposite in terms of heating up.. the header works so much better [than stock] in moving air through the engine (and intake), once you get going, the intake cools down just fine.. it's always within 2-4 degrees of the ambient air temps when I'm driving (monitored with Torque Pro app). The harder you drive, the faster it cools down.. and stays cool!

What if you could somehow fabricate something that looked like the stock heat shields to cover up your hi-flo cat? I noticed both of them are covered up that way. Not sure how closely they examine your cats, but just an idea.

Is the main advantage for the header the removal of the torque dip? Aren't there cars with e85 tunes and header back exhausts making very similar power pre and post torque dip.?

I would think that's the case.. I've seen those cars/dynos that you're talking about.. seems the one thing they all were missing was headers. But I shouldn't speculate because I'm no expert.. any combination of mods could affect the torque curve differently.. I'm just glad it worked out for me on my first attempt.

Just trying to decide which route I want to go for my next mod. Having more mid range power would be nice.

Does the factory aluminum skid plate fit with the header installed?

Is a tune required with this header? I have Visconti stage 1, im very interested in these long tube headers. It seems like everyone is jumping on this after Nameless posted their results. I know FA20 club tuned a set of P&L long tube headers, are these the same(they sure look the same)?

Yes the skid plate fits fine. You can even see it in the picture posted above on my car after the headers/pipes were installed.

Mid-range was what I was targeting as well.. I don't redline my car too often, but I drive in the 3-5K rpm quite a bit, as I'm sure alot of other people do.. I don't see how you can go wrong with these headers for the mid-range pull.

I'm still curious how a better flowing cat-back will affect the torque curve, if it does at all.. but I'm not going to be the one to find that out.. I'm satisfied with the power (and sound) I get from my stock exhaust with these mods.

I'm sure you're better off with a tune than without one.. but I'll leave that for the tuners to give a definitive answer. I think FA20club made these headers to fit their turbo kit specifically, so I don't think they're the same.

The header gives an all around completely different power band. while you can almost flatline the tq dip without the header; it seems the header creates more along the lines as a significant bump in tq throughout the same range. the car breaks loose now anytime you stomp the pedal even while cruise down the road in 2nd & 3rd gear from the bump in midrange tq.

i dont think a tune would be needed with these but imo i dont mod a car without planning a tune to maximize any part i install thats just the way I am. so generally the cars ive owned that were left stock were because there were no tuning of flash options. the headers are similar but my main intention was to use a singular unit for NA & FI purposes so the customers who kept telling me they didnt want to buy a header because they had FI dreams down the line had a viable option.

That's what I'm thinking. A heat shield like the stock one would be perfect. Freaking CA hippies!!
