I was just wonderering if anyone had a 3" exhaust on their NA. If you do did you guys see a dramatic proformance drop at the lower end?

heh alright then. i had a celica for a while (gt-s 2.2L the works!) it was a POS car with everything stock and it was rusted. anyway it was slow to begin with, but i found a local who was giving a free 3 inch system away. so i picked it up and had fun with it :D
anyway for me, it worked out well. the power increases were amazing and it didn't feel slower then before thats for sure. besides, get a 3 inch, because at one point in your life you WILL want to go turbo and this will save you some :D

Yeah I am going to buy this 3" system because I am planning on going turbo in some way eventually. So for now it will go on the NA. I have actually never seen anyone on the forums with a 3" on a NA. Maybe I will be one of the first?

A friend of mine had a 3 inch on his NA. Not even really a noticable drop in lower end performance, and the thing SCREAMED up top!!

Definate improvment up above 3500 rpm! The lower end wasn't bad at all.

Get one Boris!

Cool. Now that I think about it.. why would I care about a drop in performance if there is any. NA is already slow. lol.

I think that is the general feeling among people that actually run a 3" on an N/A. I know a few others on SF have run a 3" exhaust on an N/A and I don't recall reading any complaints from them about it aside from noise levels.

99% of the opinions on the internet are not from actual experience.

Junkie had a 3" on his 5M (2.8L) and had given positive feedback.

All of the 3" testimonials I have heard were positive. The only complaints that I have heard were regarding the sound. 3" on NA is LOUD.

I'm going to test out a 3" system on my new NA swap soon, I will report if I feel any significant loss of low end.
