I just installed a k&n cold air intake in my 94 corolla. I want to see a big effect and it makes a lot of sense that the effect would be more noticeable if I had a modified exhaust system. Do I need to replace the whole thing or just a certain part, cause the one I can find for my car is like 200 dollars.Thanks in advance
I haven't been able to find anything in my reading that says you need to modify your exhaust. Probably the best thing to do would be to contact a shop that does high performance work and ask them.
Sorry I couldn't be more help.
