Don't go twin 3" unless got decent sized stally & short diff gears or manual.Don't go twin 3" unless got decent sized stally & short diff gears or manual.
I've had 2 daily driver vy m6 cars....otr/tune/4-1's also tri-y's extractors/100 cell cats with twin 3' x-force....last one got lost it's rego before 3.9's went in.
Honestly think they all should be like that as a starting point...
If going all those mods n/a then later decide want boost may as well start over with import iron block 5.3 or 6.0 to build up...that way can keep driving car leave it on the road as long as possible.
Yeah that makes good sense.Don't go twin 3" unless got decent sized stally & short diff gears or manual.

Love it. The Varex and 4" sizing sounds awesome. Will look into Varex. thanksAs stated above
Exhausts are tricky
A big exhaust needs thought, and big resonators and mufflers
In saying that, when my LS1 was NA I had a custom single 3.5" with Pacemaker 1 5/8 Tri Y, to a 2.5" Y pipe with 200 cell cats, but, it had a "big bodied and long" 3.5" resonator and a "big bodied and long" 3.5" rear box
Boosted I'm running 1 7/8 4:1 to a 3" Y pipe with 400 cell cats to a 4" single with the biggest and longest 4" resonator that would fit and 4" rear box
The rear box is a 4" Varex, which is handy for quite starts, and when heading into my street late at night
The Varex muffler is also great as I can close it fully if the constabulary are near
Closed it is as quiet as stock, maybe quieter
But, when closed the Varex is a pretty big restriction, but fine for cruising around at low RPM
But, with the Varex fully open, at idle, or cruising, or at WOT, the exhaust sounds epic
You really need to put thought into an exhaust or you may end up with a obnoxiously loud/droning exhaust
Right. And yes I have heard that about X Force. HmmmTwin 3" Difilipo or Magna Flow, if looking for something marginally less expensive. Both sound **** hot. DO NOT buy an X Force they sound ****.
I'll take that advice and add it to my Varex research. Custom! GreatI like to get custom exhausts made up, basically pick and choose the size and type of your pipes, cats, resonators and mufflers
Cost for a custom exhaust is usually roughly the same as a generic bolt on
Plus, you don't sound like every other car like yours with a bolt on
Support your local businesses
Be aware, like any shop, they are not all the same when it comes to quality workI'll add that advice and add it to my Varex research. Custom! Great
Yeah, I'm not surprised...Be aware, like any shop, they are not all the same when it comes to quality work
Pop into a few exhaust shops, have a chat, and look at their custom work
90% of exhaust shops just do it as quickly and cheaply as possible, it is the other 10% that you will be looking for
Some shops have people who actually know what they are doing, good fabricators, great fitment, great parts, great welds, some shops have people who just throw in pipes held together with poor welds with the cheapest parts they can scavange and poor fitment
