I had the upr bigmouth. Got it for under 100. Didn't notice any gain but it did make more noise...

I bought mine for $22 on Ebay. It looks exactly like the brand name one you wanted in the first post. Here is a video that I found; it shows you how to install it.

I noticed a big difference in Horsepower and throttle response after I installed it in my mustang. I think you should save your money and get the cheap one on ebay. If you want you can get a K&N decal and slap it on the pipe like I did! Makes others think its expensive.

I heard some people in the thread talking about removing some silencer. What is this anyway and what does it do?

Anyway Good luck!!
