I'm just wanting thoughts on installing a Meth-kit before getting a new exhaust system.

Will I get too much backpressure?

Max HP with stock exhaust system is.... anyone, anyone....

 

You are losing out on quite a bit of power with that stock exhaust on there. I say go with exhaust first. You won't need any tuning for that.

 

i would review this thread if i were you...

were thinking clogged cat... due to afr in the 10's on stock exhaust due to meth but were still waiting for the op to drop the DP

 

Not worried about tuning for meth since I'll be adjusting the afrs and timing where needed. Just curios about the stock exhaust system and back pressure....

 

swap the exhst then meth. you can do every mod there is and keep the stock exhst but the fact is you are missing out on good power. do the exhst

 

so true ^^^

 

Wow, y'all loves the new exhaust first.

Oh well, I've just got 250 burning a hole and Meth seemed like a good idea. I was just uncertain on how a stock exhaust would hold up and what kind of backpressure would be created because its restrictive.

I also liked the idea of running a cooler engine and maybe going with a 2.99 pulley.
