Test pipes have big potential for power and not all test pipes sound bad. |

1. Won't pass smog. 2. Illegal. 3. Sounds TERRIBLE 4. Makes your car smell like a gas station 5. Makes you wish you listened to me when I typed the 4 reasons above. |

I've just seen people take a screw driver and just punch the **** out of their cats just get free up the exhaust.. it ended up costing them the money anyway, plus extra headaches. |

Knock out the insides only... not just bash the **** out of it. The seals, gaskets, and outter appearence doesn't change. In essence, if you knock out all the actual converter, you have a straight pipe all the way through. People with MKIII MR2's have to do this because the material in the cat decays very fast causing egine failure... I didn't mean to sound like all you do is punch holes in your ****.. lol, not at all. Texas law prohibits any person from selling, offering for sale, leasing, or offering to lease any vehicle not equipped with all emission control systems or devices in good operable condition. Violators are subject to penalties under the Texas Clean Air Act of up to $25,000 per violation. Buyers are advised to have the vehicle checked for all required emission control devices prior to purchasing a new or used vehicle. |
but getting a straight bar is basically getting the HFCs which i dont want.
|
I have the Kinetix HFC's, sound GREAT and great wieght savings. i don't recommend Test Pipes unless you've got a Turbo or upgraded ur internals, if N/A. make sure to get a tune. you'll lose on low end and some responsivness, to gain mid/high end w/HFC's(amp'd if ya go w/test pipes).
