Tsp headers w/tsp rumbler exhaust I am planning on going with the TSP Rumbler Bullet True Dual Exhaust coupled with TSP long tube 1 3/4" headers. It states on the site that these headers and this exhaust system are made for eachother (or fit eachother), so I thought it would be a good idea to go with the same brand as they will work well with eachother.
Questions:
1. Is this a reliable/solid set up?
2. How much of HP/TQ gain shall I see?
3. Is there a better true dual/header setup within the same price range ($800-900)?
4. Should I spend the extra $140 for the TSP 1 7/8" headers as compared to the 1 3/4" headers, and if so, why? What is the extra benefit in power, durability, etc.?

I would not hesitate at all to purchase the Texas Speed headers and true duals. While I don't have their headers, I do run their true duals with their bullets. The fitment was great and the ground clearance is about as good as it's going to get considering these vehicles were not intended to run duals. With that said, I would recommend you to purchase the 1 7/8 headers over the 1 3/4. The 1 7/8 headers are going to be a much better investment, whether you stay just simple bolt-ons, or move up to heads/cam/intake. You'll see increased power regarding the mods with 1 7/8 headers over the 1 3/4 headers. In my opinion, there is no better headers/duals combo out there. Kooks has their own headers/duals, but the price is quite a bit more. As far as reliability, it's completely reliable as long as everything is installed correctly. You'll also want to get a tune after you install the headers and duals. It's also the perfect time to change plugs and wires. Hope that helps you out some.

I went with the 1 7/8" primaries. When I was looking into the exhaust i was led to believe that the 1 7/8 would be a better flowing exhaust because i was planning on going with ported 243 heads and cam.
1 3/4" is a pretty standard primary size and a lot of people run them. I just opted for a little room for improvement. now take that with a grain of salt. sometimes you just have to test it yourself. you wont gain a whole lot until you have it tuned. i know after SLP lid and bellow, 1 7/8" primary into the rumbler bullet exhaust on my camaro i saw improvement but i would have seen a lot more if i had it tuned.
just know you lose quite a bit of ground clearance with that exhaust and i tried to hang it as high up as i could under the car. I have a youtube vid of the dyno and undershot of the car driving with the setup.
iirc 427zm had 1 3/4" primaries for his 434 monster build and when he switched to the 2" primary exhaust he lost some 20hp in some of his torque curve.

Thanks so much for the response. I was hoping I wouldn't have to spend the extra 140 on the 1 and 7/8" headers, but now hearing it from multiple people on this site, that is what I will do. Also, as far as clearance goes with the true duals, how much less clearance are we talking as compared to the stock set up? What do I have to worry about?

heres the exhaust running on the car as i do some street driving
and heres my dyno runs. i never got a baseline but you can look at similar stock LS1 6speed dyno pulls. i would see a bigger improvement in numbers if i had it tuned.
I mentioned the 434 build because sometimes bigger isnt better. I think you would see an improvement later on down the line with the 1 7/8" exhaust after heads (like 243's) and cam or just cam but you have a possiblity of losing hp and torque if you go too big but like i said from my research i was led to believe that 1 7/8 was a sweet spot. but you cant go wrong with either. imo

The extra $140 will be worth it in the end, trust me. My headers are only 1 3/4 and I wish I would have known what I know now because I would not have bought anything smaller than 1 7/8. In regards to clearance, you just have to be careful driving over speed bumps and going in and out of driveways that have a peak to them. It does not impact me at all; I'm just more cognoscente of it than I was before I had duals. I would also highly recommend getting on YouTube and listen to the different setups. I still have the bullets that came with my Texas Speed duals, but to be honest, they are really quiet to me. I will be replacing them with either Dynomax bullets for Flowmaster Delta 10 single chamber mufflers.

Also, guys, I will be wanting to put these tips on the Rumbler exhaust to keep the stock look. I like the stock tips better than any aftermarket. What do you think?

youre talking about the TSP true dual right? no Y pipe? because if you are then that is where the exhaust dumps. it cuts your ground clearance and is substantially louder than stock exhaust and tips are pointless since its buried under the car. they dont go over the rear axle like the kooks do. thats why they are such a great price.
quality pieces and reliable but youre not getting a full length exhaust.

Guys, I am sorry, I was not aware that they did this. Does it state that it dumps like that on the site? Can anyone recommend a setup that is true dual and fits perfectly with the headers, AND comes out all the way to the back within the 800-900 dollar price range? I want to keep the stock look.

I will look into that. Either way, I have gotten some valuable information on the TSP's from you guys, so thank you for that. I may still go with the TSP, but I really wanted true duals that went all the way back w/o having to spend extra on fabrication from a shop to extend them.

it was more of a daily driven car for me and i liked it, drone wasnt bad IMO when i drove from VA to FL for training but everyone has their preference. its definitely loud. that can be a positive or negative but the ground clearance was my issue, it was damn near touching the car underneath and i still scraped on speed bumps. i would have never been able to install strano springs IMO and not crack header bolts.

I like the looks of them as well, but had the idea of keeping it stock. You're right about the muscle car look with the true duals dumping short of the back. Hmmm.. I have some thinking to do, because you just can't beat that price 409.99. That's insanely cheap.
