My new Gibson Performance exhaust. Sounds great, runs great, and looks good too.

:cool: looks cool do you have a part number or is it universal one because on gibson website they don't have nitro.:)
How loud is it? I went with a custom done Flowmaster 40 series w/ 2.5" piping from the cat back and it isn't as loud as I wanted. Wondering if different mufflers are going to make it much louder based on the design. Contemplating today of pulling out the muffler and running straight pipes or bumping up to a 3" piping. Any thoughts?
No part #...you'll have to call Gibson directly and ask them.

This one is probably not as loud as you want it. I was going for just a better sound and some performance increase.

hey how are ya heres some thing u might want to try if u were going to go straight pipe, i would run 2' pipe and no smaller than 17/8 and for back pressure use a adjustable flap inside the pipe about 6 " from end of tail pipe so u can adjust the back pressure.
really? never heard of anything like this...intruiging though. How exactly does a system like this work though? An adjustable flap though. Would something like this be able to be controlled from the drivers seat?
Official Dyno #'s were +8hp and 10lb-ft of torque.

thats cool mandd thanks it sounds good fo shoooo
How did you do that? I have been emailing them for over a month, first they said the 7th. of jan., then two more weeks, now you have one & I'm still waiting are you a test setup or something. Who did you speak with at Gibson?( sounds great)
Yes, I was the R&D project. I've had it for a while and love it.
Thanks for the reply, Just finished emailing again, hope to hear from them soon. You are on the other Nitro site also I see. dreat
mandd-

How much did this system cost? I am really interested in the full cat-back system listed by CGS but it seems pretty pricey. I want to do both air intake and exhaust systems on my 3.7L
I just heard back from a dealer this morn. ,will ck. on when can get delivery & price for sys. tomm. morn. will post after I hear from him , but betting price is going to be pretty close to CGS price & $314.00 the lowest I've been able to find for it.
I don't know how much Gibson's is going to be. Mine was R&D vehicle and I didn't pay anything except for not having my vehicle for a couple of days.
I went Magna Flow

I went with the magna flow which supposedly boasts 10 hp 14 ft/lb's will have a pic on real soon (dirty right now) 367 bones through MPD in edmonton 6 week wait

Did you just keep the stock pipes and replace the muffler only? What is the part # of your muffler? Did you decide to change it like you considered?
