ArrivalBlue03 Posted June 19, 2005 Report Share Posted June 19, 2005 I decided to go this route because of the nice size of the factory pipe and the cost involved in a cat back system. This is not to slam Flowmaster, but be prepared before you cut off your stock muffler, there are problems with the install. I got the muffler kit part #530513, two 3" clamps and two 3.5" clamps, all 4 the Supertrapp brand band type clamp made of stainless. Three problems with my install: 1.) the Flowmaster instructions are very good about where to cut the factory exhaust, but the inlets on the muffler are WAY to big. The o/d on my factory pipes is 2.75", but the inlet on the muffler is 3"-you do the math. By this point I obviously had the factoy muffler off so I had no choice but to continue. This made my muffler install a weld in instead of a Bolt in. Luckily I have a MIG, so this didn't really cost me anything. 2.) using the muffler and the extender pipe they send you do not fit perfectly. The muffler is slightly tilted, which I don't mind, but what does bother me is the outlet location: it is impossible to get it back where it belongs, which makes it look funny. The factory tip is cut to follow the side of the body, and this puts the thing at a different angle. 3.) The Supertrapp clamps are worthless on a Flowmaster , case closed. All these things combined made my install a problem, but it is done and I will say it sounds nice, but it was a pain in the ass, and now all the joints are welded, which I didn't count on.

woodwardspecialties Posted June 25, 2005 Report Share Posted June 25, 2005 when i did mine, i went to Napa and got the adapters to go from the stock size, up to the flowmaster, this allowed for a nice fit, and i welded it all in very clean. the tailpipe extender and all fit nicely, and it looks factory unless your under the truck Link to comment Share on other sites More sharing options...
ArrivalBlue03 Posted June 26, 2005 Author Report Share Posted June 26, 2005 On my truck I could not get the tip back where it was. It looked funny because the tip was made to sit at the original angle, and it sat at a different angle from the body, so it kinda looked like you backed into something and bent the tailpipe. I just changed the tip and called it done, but it annoyed me to have to go to these lengths because I wanted the original tip in place. Link to comment Share on other sites More sharing options...
mwalls54 Posted June 27, 2005 Report Share Posted June 27, 2005 I have had that kit for 2 years now and my install was easy, clamps suck and leak, so i welded everthing. I had a exhaust shop make some couplings for the front to adapt the pipes. welded every thing up and total time took about 1 hour. that kit is actually for a HD with the 6.0 so the exhaust is a little different.

ZZZRated Posted June 27, 2005 Report Share Posted June 27, 2005 Just put the 530513 on my truck, and it fit perfectly except for having to size down the inlets, which is no big deal. Just cut a piece of pipe that slips over the stock exhaust, and slips inside the new inlet on the flowmaster. I had it all welded on for $50.00.

southsidemex23 Posted July 22, 2005 Report Share Posted July 22, 2005 Yeah i just got mine done today and it sounds really good but onw thing that really bothers me is that the tip sits at a different angle than stock but other than that i can live with it.

BmanSS Posted July 22, 2005 Report Share Posted July 22, 2005 When I had mine installed they cut the muffler to fit the pipe so its all the same size with the stock pipe in and out both ends,all welded. I went with the 70 series just right not too loud unless you gas it. Link to comment Share on other sites More sharing options...
truckin05 Posted July 23, 2005 Report Share Posted July 23, 2005 Glad you shared that!! I thought about putting one on mine, but now I think I might do some more lookin. Thanks!

oscareltemblo Posted July 23, 2005 Report Share Posted July 23, 2005 Here's something I noticed about the flowmaster 50 series that the tone changes the longeryou have it the better it sounds like if it got broken in like an engine. Link to comment Share on other sites More sharing options...
geowarr Posted July 23, 2005 Report Share Posted July 23, 2005 I had a local muffler shop put two 40 series flowmasters on mine, then back into the single tip. They had to order center in-center out mufflers to do it, and the tip was a little lower.....but all in all it sounds really good and still has the "stock" look to it. Which is what i was looking for. Link to comment Share on other sites More sharing options...
ArrivalBlue03 Posted July 24, 2005 Author Report Share Posted July 24, 2005 I am noticing a tone change too. I like it even more now. The thing sounds like pure evil. Anyway, this wasn't meant to slam Flowmaster, it fit fairly well, I just like to let others know if there are bumps in the road. Link to comment Share on other sites More sharing options...
