I have a 98 Camaro SS with thunder racing throttle body, Msd wires, underdrive pulley and a thunder racing .563 lift cam.I plan on doing headers, y pipe,and lid after I get exhaust. I like the 4 inch mufflex with flowmaster muffler but i was wonder how they fit? If they have clearence over the axle? Would i loose power with the 4 inch? any information would be appreciated

Yes, it will fit.

You will most definatly lose power over a normal cat-back. The 4 inch system is for major CI or H/C systems. Even the 3.5 inch system is too big for almost all set-ups.

Also, the flowmaster muffler does not flow very well according to most people.

My best advice would be to avoid the Mufflex systems all together and just get a normal catback. I have a magnaflow and it flows very well and sounds very good IMHO.

What are the rest of the specs on your cam?

I'd go with a 3.5 system with the spintech muffler if you don't want to change mufflers, or go with either a round magnaflow race muffler, or dynomax ultraflo race muffler. IMO, me personally, I hate flowmaster, just because everyone has it, so I would pick the spintech. I just picked up a 3.5 Mufflex with single exit flowmaster and will be putting a dynomax ultraflo muffler on it in place of the flowmaster so we'll see how it works out.

4 inch is to big unless you got a big stroker engine. 3.5 max!
