Hey guys, I ordered a Whipple , shooting for ~750-775 rwhp on low boost on e85. I think I will be removing the stock cats and trying to find a setup that works for me without cats because I dont want to melt them and possibly damage my motor or anything. I live in a condo and I dont want to have insane cold starts, they are already almost too loud with just the MBRP 3" catback street exhaust setup with stock cats. Also I am a bit concerned of smell. Ill be on e85 though so I hope the smell shouldnt be too bad without cats.
Current plan is to get the Mak cat delete pipes , possibly add some stainless steel exhaust flex sections, then run that into a magnaflow 12599 3" resonated x midpipe muffler then connect that to the 3" pipes that run to the MBRP street mufflers.
If this is too loud or smells too much, I think I would try to find the highest quality aftermarket cats and have those welded into the mak performance pipes, I think gesi has some ORX cats that they rate to 1000+ hp per bank , but ive heard conflicting reports about any cats surviving above 750 hp for extended runs or track sessions.
This sounds like a pretty complicated setup with a lot of custom stuff, I hope its not some abomination but I think it wont be too restrictive at all. If anyone has any other suggestions or recommendations , or any reason this setup wont work or wont last or will sound horrible etc , please let me know.
Ill post some pics of the inside of the magnaflow 12599 once I receive it, I am thinking its a good packed resonator x pipe design but couldnt find any inside views online.
