I want to delete the front cats on my 138,000 mile Gen 1 mid-pipe. The L has gradually lost power and mileage over the last two years. Has anyone deleted the cats and installed tubing with a band clamp?

Any idea what the actual pipe diameter is? Magnaflow recommends a 2.5" inlet/outlet slip on cat converter. So, I assume it is possible. The only item I truly see getting in the way, would be the factory heat shield.

I am trying to save money by doing the above vs. installing a Bassani mid-pipe.

Thanks!

 

take the new high flow cats to a muffler shop and get a quote

 

I've already considered that. Local exhaust shops in my area get really antsy when you mention replacing or removing cats that haven't come apart or failed completely.

 

if you've removed the old setup, because it was defective...
