I'm doin a custom 2.5 exhaust on my 98 gs.....mods injen cai, header & DP, afx udp, plugs & wires(I guess a mod)also a performance muffler.....I've searched and looked at RRE for the mandrel bends but now I need to know exactly which bends I'll need and should I add a resonator if so how big??? I'm not sure but I think the inlet on the muffler is only 2.25 if so will this be a problem or will it not really matter??? Any insight would be great...thanks

if the inlet on the muffler is 2.25, then have the piping made in 2.25. Your exhaust is only as big as its smallest point.

...that, and you can also find them at ERT for like $16 a piece. They sell only the 180* bends, but you can cut them to anything in between as needed, so you can buy maybe 3 of them and have all the mandrel bend you need. Also, I would use 2.5"ID throughout, and then step it back down to meet the muffler inlet. Try to find a glass pack with the same diameter as your piping too. The length will be dependant on how much room you have in a straight line (so if you remove the cat, you could use a longer one). Not sure what kind of length is required vs. too much. It's what I'm doing here in a few weeks, so if this isn't a good idea, well, I've got some time to rethink it.
