[quote=AtlanticBlue99]whatcha think about me going to meineke or a muff shop and throwing out 40 bucks to get them to cut out my stock cats (4 by headers- 2 on each side) and welding in straight pipe?
i know i will have less low end backpressure and the exhaust will smell bad, but i want it to be louder than my current magnaflow cat back…[/quote]
Just have them cut out your Mufflers. You will need the cats for your OB sensors. Ohterwise you will get the service light and your Maf will not work properly. Could definitley effect the performance of your engine.
My 89 gt runs with no mufflers, just the cats. Loud !!! and I get good back pressure. I will eventually install long tube headers and eliminate 2 cats. Leaving 2 down by the H pipe. LOUDER
