A few dumb questions
hey everyone, I know these might seem like dumb questions but I am not sure of the answers.
1) Are x-straight pipes legal in all states? 2) what do high flow cats do? Thanks |
Just use google
|
not sure what you're referring to wrt "x-straight pipe"?
did you mean test pipe? or x pipe catback exhaust? |
No question is dumb, my friend...NOT asking when you have doubts is dumb! DO search before asking; otherwise, some dudes here WILL blast you!

Well... 1) Not really. Many states have noise and decibel regulations. Straight pipes are loud and often exceed those limits. 2) High flow CATS are exactly what they sound like...Catylitic converters that are designed to flow a bit better than typical stock installations.. |
There is almost nothing you can do to a car that is "legal in all states" this side of an air-freshener. No...touching the cats or any part of the exhaust is not legal.

Yah I'm usaully to lazy to google it. lol. I appreciate the answers though. Thanks everyone

2. They are much higher flowing replacements to the restrictive OEM cats. They are an EASY 10-20rwhp gain depending on the type of dyno you use. I haven't seen anyone make less than 10hp to the tire, even on the smaller VQ35HR motor. |

The most I'll probably end up modding to my engine or already have done will be: intake and exhaust. Maybe pulleys. Aside from that now I'm concentrating on my suspension. |

I was quoted to remove all OEM cats (1 in downpipe and two on exhaust i think)?? What affect do you think this will have in terms of power and noise??? |

in your case, just removing the catalytics with stock exhaust may help, and stay legal. For the cross pipes, you should probably get a tried and tested catback exhaust, then decide if you want to get rid of the front cats for louder/more powerful results.
I would say to get rid of part of the exhaust that has the most restriction or by following the Tuner threads to see which replacement part has the greatest gains and allowable for your budget and preference. And then deterimine whether or not your life/driving style will appreciate the "sound" as some will find it "awesome" and others "bothersome". Im getting the FI Catback and Hi-Flow due to it power increase and will expect it to be louder,. |
