I have been preaching this for years and proved it today. If you take the stock catback PIPE and put a straight through single in/single out muffler on it and a turn down under the bumper it flows REALLY well.
The exhaust previous pulls:
Pacesetter long tubes
Pacesetter Y pipe
Stock catback PIPE with a Bullet in the I pipe and a Magnaflow straight through muffler with a 3 inch turndown on the drivers side under the bumper.
The only changes I made were:
SLP 2OTL full catback
Cut the neckdown off the Pacesetter Y pipe.
The SLP 2OTL made 5 FIVE more rwhp than the stock pipe with the straight through muffler setup.
375 vs 380.
Also, I took and shimmed the radiator hold down up 1/8 inch and it was good for 4 rwhp and 3 in tq(hood still shuts) third pull so engine was heat soaked.
Just thought I'd share.
All dyno runs were corrected.

Point I am making on the catback is guys buy $500-600 catbacks to make 5 more rwhp that I did with the stock setup with a good muffler.
As far as the washers go, put 4 washers on the bolts the under the radiator hold down to shim up the lower airbox.
Simple, and no I am not going outside to take it all apart to take pics of that lol.

Kinda like the new 5thgen guys buying the $400 muffler delete system, that costs about $10 to replicate.
As far as the washers, I don't have a Camaro, so just whenever you get a chance to take a picture, I am interested.

Ahhh I see what you are saying and yes, been doing this instead of buying the whole catback for 15 years.
