Has anyone replaced their mufflers with Flowmaster Delta 40 series? I'm taking BLU in on Wednesday to get them put on with Flow 4' tips. (I'll be keeping my stock parts...of course) Sound clips? Anyone? Thanks!!!!

I have the new super 40's. I had an X pipe made which replaced the center resonator. I went with 3 inch pipe all the way back and kept the stock tips. Sounds good, i love it at WOT. I dont know if it is what i will be sticking with forever though. Over all it is a big improvement and you will be satisfied, but you may want more as time goes on.

Flows or SLP

Anyone thrown Original 40's on their GTO? I'm considering either those or the SLP Loudmouth mufflers.

Any comments, opinions, suggestions?

For the 40's, what position did you get the inlet and outlets? 2.5"?

Thanks
