i bought a magnaflow catback system about a month or 2 ago & im back already. i bought the system 16523 & i want louder... ive been searching & searching but im wondering if there is a smaller muffler i can put on that would fit the demensions. maybe a borla? il be waiting for your reply avfrog lol. i like the system but i should have just done a custom exhaust at a shop with what i wanted.. got to learn some how...

 

Swap the muffler with a shorter muffler such as the 12198 and add extension pipe. Depending on how much louder you want your exhaust, the better thing would be to add 94106 magnaflow cats. With those cats your system would sound similar to my old system

 

Replace it with a 4" round Magnapack, screw the oval bodies. If you want to hear it, go round body, or hi-flow cats with short case mufflers ( Magnaflow 11s, 14s, Borla ProXS 14s, Borla S-type 16" ).

 

^ umm... AGREED

 

S-type are only 10" long case and 5" round.

 

Really? huh, thought I seen one that was 16" once. Guess not. That explains how they pack so much thunder though.

 

I vote for a 4" round Magnapack and high-flows........ of course only if you REALLY want to hear it!

 

ok my only concern with that is it won't work with the exhaust set up i have .. its a si/do system & all of those are si/so

 

Magnaflow Y pipe part #10778

 

Y pipe at the muffler exit to split dual out.

 

the overall length on the muffler i have is 24" right?

 

Yes the overall length outlet to outlet is 24"s. The muffler body/model itself is the 18" body.

 

exactly... thanks... im trying to figure something out that will fit as close as possible to the current muffler overall length (24") cuz i dont want the tips out to far or in to much

 

That wont effect anything, if you have to trim anything, trim the intermediate pipe down. Put the muffler in first, make inlet/mid pipe measurements and cut the midpipe to proper size.
