Alright I am gonna continue to run my hedman long tubes along with 2.5" piping on each side with 2 spintech frame clearance pipes to go under the crossmember and then straight back into spintech cruiser mufflers which are only 2 1/4" thick.I am gonna dump them off right before the rear axle. The car isnt lowered but the setup I have now is just ridiculous for ground clearance. my setup now consists of the hedman lt's with 2" piping on each side that dips under the crossmember back into dynomax super turbo mufflers that are like 4 1/2" thick and drag the ground all the time. So what do you guys think about this setup? Should I change anything? Should I keep the frame clearance pipes or just have them go around the crossmember? Any suggestions are welcome.

 

I am trying to figure something similar to what you are doing with my 92 Z28. Are you using 68460 long tubes? I am going to use 2 1/2'' or 3'' piping back to two small 40 series delta force Flowmasters. My car is not lowered either, so I think there will be enough room for them. I am going to use turndowns in front of the axle. I have not heard any Spin-Tech mufflers, do they sound aggressive?

 

Yes My those are what hedmans I have. I have been told that they sound really agressive. I have got to change something cause my car drags on everything so i think I will be safe with a muffler thats only 2 and a quarter inchs thick.

 

Spintech can also custom make you some mufflers. I was going to go with the cruiser mufflers but was concerned with possible flow restrictions due to the reduced case size. After talkin with Ron at spintech we decided on a compromise and they built me a pair of 3" thick by 16" long mufflers. He said the wouldnt restrict flow because, although they were thinnner the 16" case length made up the difference.
