I just purchased the stillen y pipe today and was reading the instructions and it appears as thought the front cat stays in place. Is it this way with Cattmann's y pipe also?

Also, does the Catmann pipe have mandrel bends? Stillens does.

I'll post on the performance next week.

 

i just recently install cattman y-pipe on my 00 se cali spec...it moved the lower precat only...had it 4 days now and car pulls very good especially above 3k
