i think stock piping is 1 7/8", and since you already have a motor, try vivid racing for the mrt headerback, but have them take off the muffler, thats the budget route to go and should give you some nice gains

did he mean have them take off the cats? cause i am going to of course have them take off the Stock muffler to replace it with the Straight threw N1 2.5 inlet .... either way , was just looking to see if i should replace the cat or just the intermedate pipein with 2.25 pipe

He means you should order the MRT system (headers, High flow cat, mid pipe and muffler), but tell them to leave off the muffler section. This will save you some money, and let you use your N1 muffler... You will have to have an exhaust shop mate the muffler to the MRT mid pipe. Make sure they use 2.25" piping and have them put on a flange to bolt to the MRT mid pipe...

Hope this helps...
