- I dont want to spend too much time explaining the exhaust stuff since I am kinda tired right now. But it depends on the car. Going with a smaller diameter is a bad idea on a 3.8L engine because it is too big. If you email me, I can take my time in writing you a longer explanation. With the import engines, you have to remember they make 110-150HP from the factory using already ported and polished heads from the factory, tuned exhaust headers. That is the only way they can do it. That is why when an import puts a header on their car, it gains maybe 5-8HP, while a domestic engine like ours by modifying the exhaust manifolds can yield 10-15HP easy without trying hard. American engines are not tuned, dont have tuned exhaust and other misc trick the Japanese use to make more power out of their 4-cylinders. American companies have to detune their engines or else they make more power than the price bracket each car is sold in. If you have a ported and polished and all other mods that I am thinking of for the L36, you can make over 330HP and over 350-360 torque (flywheels) from these engines, but you don't want to give that to the public #1. #2 having that much power in a car costing $23,000 (new for a Bonneville SE) would sell it alot but it would probably cost a little more (for all the machine work on the engine and such). But it would kick ***. And one more question, what kind of imports do your friends drive so I get a better idea of what kind of ideas they are giving you. I know pretty much every import and domestic engine made (that'* my job) and I dont discriminate between Domestic and Import.
- Geez... I have no idea what you are talking about...
You can't do anything else for the exhaust...........
yeah.... Hint (something import guys do, see if you can guess Allmachtige). Let'* see if you know your imports.
- You can get a carsound cat off of eBay for about $50 bucks and some shipping. Those are good cats, have used them before and they work well. I get autosound cats, but all that guy does on ebay is sell carsound cats so he get'* it probably $10 dollars cheaper for each one than I do. Hope that helps.
