Thats the same set up I have except I have the pypes tips. It sound great with no drone. But If your leaving on the stock H pipe and just want some loud azle backs get the boom tubes or SLPs or even pypes muffler deletes. If your wanting an actual muffler thats pretty loud go with MAC or the magnaflow magnapacls or even stingers. The pypes mid muffler system sounds great with the stock H as well.

 

+1000 for boom tubes

 

The loudest mufflers are no mufflers......... hehehehe

I tried mine with rear muffler delete pipes and an otherwise stock system. Sounded great on the track but frankly a bit tedious on the street.

I tried no mufflers compared to boomtubes and actually got less drone. No mufflers is win.

 

Magnapacks by Magnaflow sound bitchin' on a 289, IMO


sorry, no sound clip

 

where can i find these boom tubes at and what size do i need for an 05gt? thanks

 

www.brenspeed.com sells them for $329.

But also putting on a set of high flow cats will reduce the muffling affect from the stock cats.

 

Those are all good choices. However, if you want to take a chance, Pypes has a new system very similar to the SLPs and is only $200 until February 15. Great deal.

But whatever you decide to do, a muffler delete is what it seems she wants.

 

if i went with the o/r h pipe and didnt get a tune right away, whats the worse case scenario? check engine light? and if so, would it actually mess with anything having the check engine light? also, would it affect her warranty having the o/r h pipe? thanks

 

i would just put on the series 40 flowmasters and see how she likes them, i think if you went real loud your just gonna be replacing them to something quieter in the future,i will be changing mine because its way to loud,neighbors complaning and sounds like im flooring it everywhere i go.
