Bored/raining so time for a new exhaust Been running a hooker catback and just taking off the muffler and putting a turndown on all the way at the back. Needless to say a 3" Y-pipe going into a single 3" exhaust pipe probably isnt the optimal setup for a 650-700rwhp car but it worked. After upping the boost a couple PSI and seeing no gain I though maybe the exhaust was starting to become a restriction..
Plus the Kooks Y-pipe has a pretty crummy merge, not as bad as some but not the best by far. I was going to do a true dual/X-pipe but I hated the thought of adding the weight and having another muffler on the car on the left side. I dont care much for header mufflers hanging down plus a lot of 'street car' series muffler rules say the talipies have to be closer then 12" to the rear axle, so..
I thought I would try a 3" to 4" flowmaster collector, 4" dynomax bullet and a turn down. Cost me 68.00 in parts so its a cheap experiment. I got lucky and the hooker over the axle pipe and intermediate pipe had the perfect bends to join the flowmaster collector with the Kook's Y-pipe. Turned out pretty good, and it has a ton of ground clearance. I didnt change anything else on the car so I'm curious to see if this does any good at all over what I was using. I used to put the hooker muffler back on for street driving but with the gutted cats acting as resonators and the 4" bullet it really doesnt sound that bad cruising aroung - pretty loud at WOT though

It turned out OK, I ran out of gas for my MIG welder and it was after 5pm when I started. Ended up using some 10 year old flux cored wire I had laying around to weld it with - its like welding with a hand grenade but it worked lol.

I'm not going to really be driving the car enough anymore to worry about drone. The 3" straight pipe was kind of raspy and this is realy deep sounding - kind of like a school bus that the muffler fell of
I really need a bigger cam

Either the hooker cat back muffler is able to flow enough for nearly 700rwhp or the the pipe before it was too small - find out soon enough
Hey Kevin....nice exhaust. It's been a while since I've posted/viewed on here. It's funny, however, that I came across this thread because I was thinking of doing the same thing to my camaro. I was thinking of Kyle's and Stenod's white ws6's exhaust. Similar setup as yours. Do you have any videos of the new exhaust? I saw the video of the hooker exhaust.
Thanks
Andy
