Had the Exit28 X-pipe installed a few days ago and I am not sure if I notice a difference. There may be less popping yet not at the 75% most claim. I am not sure of HP gains either. The stock H-pipe had at least a 2.5 inch hole in it.
My ? is does it matter in the 2001 if an X-pipe was present because of the larger crossover in stock H-pipe. And does it take time to notice less popping and HP gians? Also, did I lose HP by changing out the stock H-pipe since the crossover hole was larger than I expected. Thanks ahead of time for any helpful comments. :chevy
