Damn just pickep up the phone and orderd a set of testpipes for the 348...yet another part i dont "need".. Oh well, hope they sound great with the capristo level 2 What your exprenice in sound level increase..Is it barely noticable or how?
My capristo level 2 with hyperflow sounds better than yours....because it was shipped to me via FEDEX....hahaha just kidding. Barely noticeable?? You put testpipes with capristo together and they'll get you very noticed so sure. Enjoy the sound. Cheers!
If you have the stock exhaust on it I don't expect a lot of difference in sound with just the test pipes. At least that's what I noticed with my stock duel can exhaust and test pipes.
At least in the US the cars are equipped with catalytic converters as part of the exhaust that use a chemical reaction to completely burn any excess fuel in the exhaust and convert some of the exhaust gaas to less harmful emissions. they tend to add alot of heat to the engine bay and have been known to fail causing excessive fuel to catch fire and burn the cars. A test pipe replaces the catalytic converter (presumably for a short time). Some people leave the catalytic converter out of the car and just leave the test pipe in. Less restriction and heat in the exhaust are the primary benefits, with a slight increase in low end torque and a throatier exhaust sound as additional benefits. BT
Ok so now I know. You take the cat off and weld a pipe in its place? The problem here is you have to test the car once a year. If it is younger than -89 it has to have the cat installed, otherwise heavy fines. //B//
