    YES!! Go to ebay and type in High flow converters!!! There only $37 a piece! Choose the universal 2.5' or 3' inch option and have an exhaust shop install........DO NOT try SLP or any other name brand that will rip you off!

    Here you go bud....they work great!! You can choose either 3 or 2.5-inch.....I purchased the one's pictured below on ebay....had them welded on by exhaust shop for $30.00!!! Good luck!

    Sorry for the OP, but I was wondering Mr. Luos, if you might have you build documented anywhere online? I've got my 402 short block ready to go, and I think I've got TONS of questions. Thanks all, and let's carry on!

    Get $37.99 cats on eBay. Done!

    I have magnaflow and mine is LOUD and it resonates like hell. I hate the way mine sounds. Its at its worst in like 2nd gear between 2000-3000 rpm. It is almost to the point of being embarrasing. I bought a bullet and I'm going to have it installed right after the Y-pipe and keep the muffler also. I really hope it fixes this.

    I have the SLP PowerFlo cat back with QTP LT's and ORY and get no noticeable rasp. My car did have some exhaust odor but a better tune and some welding fixed it up.
