Default Benefit of 2" exhaust system

Hello all!

I have been lurking around this site for a while and have consistently read that installing a 2" exhaust system and new headers is the best bang for buck.

I was hoping someone here could clarify just how great an advantage this modification will yield. Any info regarding economy, performance and overall feel would be greatly appreciated.

At present my sierra is stock, but this is the first upgrade i am seriously considering.

Cheers,
Robert

I run a header and a short 2.25" exhaust system (less than 1m in length) that is dumped just in front of the rear wheel on a Samurai. I used a short connector poece to the header then a 40 cm long "blue bottle" "muffler" then a 70 degree tail pipe. I found this set up to be quite efficient with both power and mileage. I am running a 1.6L with stock gear ratios and 31" tires.

Hopfully this helps...sorry I don't have more imperical data to back up my results......but it feels good and sounds really mean!!! Like a sewing machine on steroids!!!

I too have a Samurai (1988) that I just put a Tri Mil Ceramic Coated header with two inch exhaust going though a Cherry Bomb glass pack muffler. I also put on a K & N Mega Flow Air Intake/Filter and the combo is very noticable in performance, acceleration, and a very cool rumble deep sound. Love it!

Zunken, that setup is almost exactly what i have been looking at. Does it do much for the top speed? My motivation is the dream of being able to drive uphill on a highway and not have a constant stream of traffic overtaking me.

Is the filter and exhaust enough for this or would i need further mods (new carb for example)

Default i have a dream

we all have that dream, a good beathing exhaust system is cheapest way to get a few extra horsepower but if you look at the endless stream of cars that are over taking you , you will notice that they all 3 or 4 time the size engine your suzuki has. there is no substution for cubic inches!!!
just take comfort in the fact you are driving a much funner vechicle than they are!!!!

sorry but i dont think that anything you do to the 1.3 engine (at least cheap) will ever be able to pass those long line of cars.

but i have a pacesetter header, 2 inch exhaust, flowmaster 40 series muffler, and K & N filter . and this being said, it has more pep around town - but yeah never gonna pass those cars - they almost always will pass you. BUT with this set up, you might pass one every now and then, and just be happy and wave to those people.

As squid says, there is no substitute for cubic inches. When I want to blast by the long line of cars I do it in my Dodge Ram with Turbo Cummins Diesel or my 67 Chevelle. With my Sammy set up, I also have 4.16 gears, 6 inch SPOA, 31 inch Truxus tires and it is 55 mph max on a flat road. It is fun in the sand hils, rocks, mountains, etc and it gets me to those areas when I need it to, or I tow it there with the Dodge. It is a lot of fun to drive and it turns heads. Most hard core jeepers turn up their noses and sneer, but I clear areas they can't and have spent about 1/3 of what they have to get my Sammy modified.

lol... i used to be that jeeper guy that has come into the zuk world... it is different not being able to power down but one thing you certainly can do is HAMMER down on the trails and just go up over and through stuff those guys just dont even understand how. if you took away all their lockers, lift and rubber they couldnt even make it TO the trails. i used to wheel a 99 TJ with a 31"s and go farther faster than those guys with rubi's on 35"s that would scoff at my rig. can't wait to bring the sami out on trail rides this summer

Since I have got my 'zuki I have waaaay more friends! That is because I'm the only one that can rescue them and then procede to show them how it is done!

Since I went with the 1.6L I have plenty of power, I can 60 mph empty and 55 mph towing a skidoo trailer (yes with a skidoo!). All for close to 30 mpg. Gotta love it.

Pilsner... NICE!!! what kind of exhaust did you put back on for the 1.6L? blue bottle? is the header stock?

Zuken... did you put just a K&N filter on or is the "K & N Mega Flow Air Intake/Filter" you reference an actual replacement of the stock air box?
