I am just looking for some exhasut suggestions to put on my newly acquired GXP. I really like the way the 5300 sounds with no mufflers, but is this good for the motor? Some motors dont like the reduced back pressure.
If not, wht combo produces a nice deep/throaty loud v8 sound?
Thanks,
Eric

itll be fine with no mufflers, but honestly id rather a nice chambered muffler on it.
02-01-2010
which would you reccommend as far as mufflers go?
02-01-2010
Can't go wrong with Flowmaster for a V8. I've always liked the way they sound. Magnaflow is good but a more mellow note.

I want loud, all the vids i have watched on youtube of magnaflow and slp, are really quiet. What about flo pro?
02-01-2010
what is with people and wanting loud cars with no tone or smooth exhaust? straight pipe the whole car and be done with it then.

I never said i didnt want a nice deep tone, thats exactly what i want just not as quiet as magnaflow and slp systems for these cars.

is this loud enough?lol YouTube - Grand Prix with flowmasters(GXP) YouTube - grand prix gxp drive by to me that is loud, i do post these vids sometimes but rather than try to explain what flowmasters sound like on the gxp i just let them listen, to me i love it and it sounds good but its not for everyone because it is pretty loud. just 2 single chamber flows with res delete and knn intake. enjoy your new gxp whatever you choose.

I personally think flowmasters are crap i going with gibson superflows. I havent seen anyone with them and think they will sound good. I'm just waiting on my doug thorley headers to get done before i do the exhaust.

man i wish i knew how to get headers i got everything else, i think flowmasters sound good in my vids but even in person they sound much better to me specially now that they are broke in ill have to get a new vid up there a little cleaner sounding.

I have noticed that the Flomasters do take a bit to get "Broken In" I had a buddy with a 5.3L and had Flowmaster 40's I believe. We drove 14 hrs straight the day after he got them installed. They kept getting louder and louder as we went. By the time we got back home they sounded completely different pretty throaty.
Has anyone tried Magnaflow on the GXP's yet? I love them on my GTP.

yeah its the only catback made for the gxp there are others for the gtp that can fit the gxp. they sound pretty good i like them with out the resonatorOriginally Posted by rynoman03

Have yo utalk to williamGt i dont know if the group buy is still going it might've closed, if thats so you might have to pay $960 on the doug thorley website

sorry dont got a grand to drop on headers, maybe 5 or 6 hundred.

We have had nothing but good things to hear from customers about the SS catback from Magnaflow. It compliments a daily driven car perfectly.
They are also on sale for the next two days
02-13-2010
they were $599 in the group buy the only reason why i bought them i still have to get money together for the rest of the exhaust. i'm thinking it will cost me another $600-$1000 for the headers back exhaust.
02-14-2010
classic chambered mufflers sounds good. I run a open cut out after the resonator.
02-16-2010
Same reason I bought them now instead of later, but because it's been long enough waiting that I've been able to get the money together. Still, the cam is the big restriction in my car (then the cat), not the exhaust manifolds. But saving $360 is worth doing things a little backwards.

What is the difference between a hogan downpipe and just cuuting the cat out of a exhaust system and replacing with a pipe?
