Swapped out the stock H for my MAC O/R H-pipe last night. I'vebeen running with it since the head replacement a couple months ago. I noticed that there was a noticable loss in low-end torque as the tires wouldn't blow off quite as easily in the cold temps. It got in the upper rpms before they would go up. Anyway, first run right off the street: 399rwhp/377rwtq SAE
Let it cool for ~10 minutes while we BS'ed about cars in general. The second run was better: 409rwhp/379rwtq SAE
Not too bad for an old K&N bigmouth filter, MAC O/R H-pipe and Mac 2 1/2" catback. :-D
My torque woes will soon be fixed witha 2.77 pulley and a Predator tune. :burnout:
BTW, drove George of MGW's E55 today. That sumbitch has some SERIOUS low-end torque! Super solid car... but no real personality. I'd still have one if I had the coinage. :coolman: :coolman:
