Andrew Bayley Posted April 17, 2006 Share Posted April 17, 2006 I'm looking at a set of sidepipes and keep coming across this “Patriot†sidepipe. I'm intrigued, but also concerned about the 2†inlet pipe. Does anybody know what the inner diameter is of the muffler section? Reason I’m asking this, is because I’m thinking about cutting the 2†section off and welding it to a 2.5†pipe. However, if the muffler inner diameter is only 2†(or even smaller like most exhaust manufacturers do without informing you) then there really isn’t much of a point in cutting the 2†section off. I also found a set of Dynomax sidepipes that have a 2.5†advertised inlet, but their price is almost $100 more for otherwise the same thing. Is the extra half an inch worth a hundred bucks on a 450 hp SBC or would the Patriot pipes work just as well? (Dynomax pipes with 2.5" inlet) Quote Link to comment Share on other sites More sharing options...

OlderThanMe Posted April 18, 2006 Share Posted April 18, 2006 or you could just try to get the sidepipe covers and make your own pipes to go underneath the covers with your own glasspack of choice. That would be the easiest. Quote Link to comment Share on other sites More sharing options...
Andrew Bayley Posted April 18, 2006 Author Share Posted April 18, 2006 Any ideas where I can get just the covers? Quote Link to comment Share on other sites More sharing options...
OlderThanMe Posted April 18, 2006 Share Posted April 18, 2006 you could probably get patriot to sell them to you. or you could have a shopcut them out. or you could go to www.mcmaster.com and get some material from them and bend it. Would not be as pretty but it would still be cool. go down to expanded metal down in the raw materials section. then decide what you would want.

Dudeboy Posted April 19, 2006 Share Posted April 19, 2006 Check out Dr. Gas - drgas.com (nascar exhaust specialist)on the high dollar end but you can put together a 3 inch piping to complete the patriot exhaust. Also, there is 1969-1972 Corvette competition side exhaust that may be 3-4 inches diameter from end to end as another option. Summit has them in Black, I do not know if they have it in chrome?

Dudeboy Posted April 19, 2006 Share Posted April 19, 2006 Summit or Jegs should have the covers. Check a hot-rod shop in your area that sell lake or rad-rod sidepipes. Quote Link to comment Share on other sites More sharing options...
Andrew Bayley Posted April 20, 2006 Author Share Posted April 20, 2006 OK, I just got off the phone with the manufacturers at Patriot Exhaust. The inner diameter of the muffler section goes down to 1 and 5/8th on an inch. Ouch! Gonna call up Dynomay next. If they aren't any better, I might have to go commando and make my own set.

Scottie-GNZ Posted April 25, 2006 Share Posted April 25, 2006 THE Andrew Bayley? :D Quote Link to comment Share on other sites More sharing options...
Andrew Bayley Posted April 25, 2006 Author Share Posted April 25, 2006 THE Andrew Bayley? :D Or so I'm told! Started fartin' around with the old girl again trying to jump start my enthusiasm again. So far, its working! Got the engine dropped back in last night, need to finish up the final wiring, drop in the radiator, then tackle the new exhaust project. Got a big car show in late June I'm hoping to attend (St. Ignace Michigan). The (new) wife is really looking forward to going so I don't want to disappoint.
